Important Safety Precautions

Prior to shipment from the factory, JVC products are strictly inspected to conform with the recognized product safety and electrical codesof the countries in which they are to be sold. However, in order to maintain such compliance, it is equally important to implement thefollowing precautions when a set is being serviced.

Fig.1

1. Locations requiring special caution are denoted by labels andinscriptions on the cabinet, chassis and certain parts of theproduct. When performing service, be sure to read and com-ply with these and other cautionary notices appearing in theoperation and service manuals.

2. Parts identified by the symbol and shaded ( ) parts arecritical for safety.Replace only with specified part numbers.Note: Parts in this category also include those specified to com-

ply with X-ray emission standards for products usingcathode ray tubes and those specified for compliancewith various regulations regarding spurious radiationemission.

3. Fuse replacement caution notice.Caution for continued protection against fire hazard.Replace only with same type and rated fuse(s) as specified.

4. Use specified internal wiring. Note especially:1) Wires covered with PVC tubing2) Double insulated wires3) High voltage leads

5. Use specified insulating materials for hazardous live parts.Note especially:1) Insulation Tape 3) Spacers 5) Barrier2) PVC tubing 4) Insulation sheets for transistors

6. When replacing AC primary side components (transformers,power cords, noise blocking capacitors, etc.) wrap ends ofwires securely about the terminals before soldering.

Power cord

Fig.2

10. Also check areas surrounding repaired locations.

11. Products using cathode ray tubes (CRTs)In regard to such products, the cathode ray tubes themselves,the high voltage circuits, and related circuits are specified forcompliance with recognized codes pertaining to X-ray emission.Consequently, when servicing these products, replace the cath-ode ray tubes and other parts with only the specified parts.Under no circumstances attempt to modify these circuits.Unauthorized modification can increase the high voltage valueand cause X-ray emission from the cathode ray tube.

12. Crimp type wire connectorIn such cases as when replacing the power transformer in setswhere the connections between the power cord and powertransformer primary lead wires are performed using crimp typeconnectors, if replacing the connectors is unavoidable, in or-der to prevent safety hazards, perform carefully and preciselyaccording to the following steps.

1) Connector part number : E03830-0012) Required tool : Connector crimping tool of the proper type

which will not damage insulated parts.3) Replacement procedure

(1) Remove the old connector by cutting the wires at a pointclose to the connector.Important : Do not reuse a connector (discard it).

Fig.7

cut close to connector

Fig.3

(2) Strip about 15 mm of the insulation from the ends ofthe wires. If the wires are stranded, twist the strands toavoid frayed conductors.

15 mm

Fig.4

(3) Align the lengths of the wires to be connected. Insertthe wires fully into the connector.

Precautions during Servicing

7. Observe that wires do not contact heat producing parts(heatsinks, oxide metal film resistors, fusible resistors, etc.)

8. Check that replaced wires do not contact sharp edged orpointed parts.

9. When a power cord has been replaced, check that 10-15 kg offorce in any direction will not loosen it.

Safety Check after ServicingExamine the area surrounding the repaired location for damage or deterioration. Observe that screws, parts and wires have beenreturned to original positions, Afterwards, perform the following tests and confirm the specified values in order to verify compli-ance with safety standards.

1. Insulation resistance testConfirm the specified insulation resistance or greater between power cord plug prongs andexternally exposed parts of the set (RF terminals, antenna terminals, video and audio inputand output terminals, microphone jacks, earphone jacks, etc.). See table 1 below.

2. Dielectric strength testConfirm specified dielectric strength or greater between power cord plug prongs and exposedaccessible parts of the set (RF terminals, antenna terminals, video and audio input and outputterminals, microphone jacks, earphone jacks, etc.). See table 1 below.

3. Clearance distanceWhen replacing primary circuit components, confirm specified clearance distance (d), (d’) be-tween soldered terminals, and between terminals and surrounding metallic parts. See table 1below.

4. Leakage current testConfirm specified or lower leakage current between earth ground/power cord plug prongsand externally exposed accessible parts (RF terminals, antenna terminals, video and audioinput and output terminals, microphone jacks, earphone jacks, etc.).Measuring Method : (Power ON)Insert load Z between earth ground/power cord plug prongs and externally exposed accessi-ble parts. Use an AC voltmeter to measure across both terminals of load Z. See figure 9 andfollowing table 2.

5. Grounding (Class 1 model only)Confirm specified or lower grounding impedance between earth pin in AC inlet and externally exposed accessible parts (Video in,Video out, Audio in, Audio out or Fixing screw etc.).Measuring Method:Connect milli ohm meter between earth pin in AC inlet and exposed accessible parts. See figure 10 and grounding specifications.

1.8 HOW TO TAKE OUT THE CASSETTE TAPE IN AN

EMERGENCY

When the cassette tape cannot be ejected due to a failure inthe electrical circuitry, take out the cassette manually as de-scribed below.Note that the following method is not applicable if the mecha-nism itself is fractured and becomes stuck as a result of this.

(1) Remove the left side cover from the main body. (See "1.1.1Removing the left side cover".)

(2) Apply 3 V DC to the terminals on the top of the loading mo-tor (Red wire: +. Brown wire: -) to perform the unloadingoperation little by little. Perform the unloading operation lit-tle by little for the tape may be slackened or damaged ifunloading is attempted all at once.

Fig. 1-8-1

(3) If there is any tape slack, wind the tape up by inserting apointed tool (such as a chip IC replacement tool) into theshaft above the capstan motor and turning it in the directionof the arrow.

(4) Repeat the operations in steps (2) and (3) until the tape iswound up completely inside the cassette. Take care not todamage the tape during the operation.

(5) Ensure that the tape has been wound up completely, pushdown the release lever of the cassette housing and take outthe cassette.

PB CLOG LEVEL

REC CLOG LEVEL

109 Threshold AD value of the temperature that forces the long pause period to 3 minutes

(Initial : 30 minutes) under low temperatures (0 – 255). The following table shows the relationship

between the set internal temperature and the threshold value.

80 The threshold AD value of the temperature sensor that lowers the dew threshold at low temperatures

(0 - 255). (The setting value of 80 corresponds to about 10°C.)

26 The threshold level of the playback head clog error indication (0 - 31).

The relationship between the threshold value and the error rate is as shown below.

Error rate = Threshold x 10 (tracks) x 30 (frames)

When the threshold setting is 26, the error rate is:

26 x 10 (PAL: 12) x 30 (PAL: 25) = 7800

1 The threshold level of the recording head clog error (detected during short playback in continuous

recording) (0 – 7). The relationship between the threshold value and error rate is as shown below.

Error rate = The value of PB CLOG LEVEL error rate x the setting of REC CLOG LEVEL.

When the threshold setting is 1, the error rate is : 7800 x 1 = 7800

1.11 REAL-TIME CLOCK

IC405 (RS5C314) on the A/L/S board is the real-time clock IC, which transfers the time and calendar data to the CPU by means of serialtransfer. BT401 is the secondary battery that backs up IC405 while external power is not supplied. It supplies a voltage of 3 V and iscapable of backing up for about 3 months after it has been recharged for 4 hours. When external power is supplied, the AL 3 V poweris sent through D401 to pin 8 of IC405, then through D402 to BT401 for recharging it. When the power supply stops, the AL 3 V powerdisappears so BT401 starts discharging power, which is sent through D401 to pin 8 of IC405 for backing up the clock.

1.10 EEPROMS

(1) EEPROMs and stored data

After replacement of a board or EEPROM, the EEPROM contains no data at all. But it is initialized automatically when the power isturned on. As the adjustment data, menu data and IEEE1394 are reset, it is required to readjust them.

(2) IEEE1394 ID setting methodA device equipped with IEEE1394 contains the ID prescribed in the IEEE1394 standard in its EEPROM. The ID assigned for eachdevice is written in the memory at the time of production and the ID label indicating it is attached to the side of the mechanism.After replacing the EEPROM or A/L/S board, be sure to re-set the ID in the EEPROM.

IEEE1394 ID Setting Procedure

The ID is an 8-digit hex code, composed of the model code in the highest byte and the individual code in the 3 lower bytes.As the model code is initialized automatically, it is required to set the individual code in the 3 lower bytes.In the OTHERS Menu, select “MEM.EDIT” (Memory Edit), select the addresses for the ID data and set it directly. Theaddresses of the 3 lower bytes are as shown below. Set the ID data by referring to the label (ID: 41xxxxxx) attached on theside of the GY-DV300 mechanism.

MECHANICAL ADJUSTMENTS

2.1 BEFORE ADJUSTMENTS

2.1.1 Precautions

1) Be sure to apply a screw securing torque when attaching apart.The securing torque should be 0.04 N-m (0.4 kgf-cm) unlessotherwise specified.

2) Always unplug the power cord of the set before attaching,removing or soldering a part.

3) When unplugging a connector, do not pull the wire but graspthe connector body.

4) Do not make an adjustment or rotate a potentiometer blindlywhile the source of trouble is not identified.

5) Before adjusting electrical circuitry, be sure to wait for morethan 10 minutes after turning the power on.

2.1.2 Regarding LP mode [IMPORTANT]

The GY-DV300 is equipped with the LP mode. Although the trackwidth of DVC SP mode is 10µ , in the LP mode this is reduced totwo-thirds, so even with the slightest change in condition it maybecome impossible for the head to go on-track. As explained in theinstruction manual, block noise and sound errors may be generatedin the LP mode depending on the tape being used or the usageenvironment. Please be especially aware of the following points.1) Compatibility of tapes recorded on other unit

Playback is possible only with tapes recorded on the sameunit. (Self-recorded playback only.) Block noise and sounderrors may occur when playing a tape that has been recordedusing another unit.

2) Compatibility with environmental conditionsWhen playing back at normal temperature a tape that hasbeen recorded in a low temperature (or high temperature)environment, block noise and sound errors may occur. Thesame may occur in the opposite situation as well.

3) 80-minute tapeIf an 80-minute tape is used, block noise may occur duringplayback even when playing a tape that has been recordedusing the same unit. Therefore 80-minute tapes cannotbe used.

Regarding Head Drum Change

1) When the head drum is exchanged, compatibility with tapesthat were previously recorded using that unit will be lost,and block noise may occur during tape playback. When per-forming a head drum exchange, be sure to explain this tothe customer beforehand, and encourage the customer totake appropriate steps as necessary such as dubbing record-ings in SP mode.

2) On maintaining compatibility

Although there are restrictions as outlined above, as a partof your service efforts to maintain compatibility after headdrum exchange, we recommend the following measures:

1 First, record in LP mode before carrying out the headdrum exchange.

2 Carry out drum exchange and perform compatibilityadjustment.

3 Play the tape recorded in 1 and check to see if the RFwaveform is good. If there is a severe drop in the wavedue to mistracking, please fine-tune the RF waveformwithin the limits of the adjustment specification to bringit closer to the track pattern prior to head drum exchange.

2.4 MAINTENANCE AND INSPECTION OF MAJOR PARTS

Periodical inspection and maintenance are requisite to maintainthe initial performance and reliability of the product. Table 2-4-1(Maintenance & Inspection List) has been compiled assumingstandard operating conditions, and the specifications in the ta-ble are greatly variable depending on the actual operating envi-ronment and conditions. Remember that, if the maintenanceand inspection are not enforced properly, the operating hours of

2.4.1 Layout of major parts

the product will not only reduce considerably but otherunfavorable influences may produce.Rubber parts may deform or degrade after long period of stor-age even if they are not used in this period.The service life of the drum is variable depending on the tapeused and operating environment.

2.4.2 Maintenance and inspection list

1) The 6000 H maintenance consists of a replacement of the entire mechanism assembly.2) When mounting the capstan motor on the main deck, control of the verticality is required. Therefore, when the capstan motor

reaches the end of its service life, the entire mechanism assembly should be replaced.

Table 2-4-1

Page 28: JVC GY DV300U UZ E Service Training Manual

2-7

2.4.4 Oiling and greasing

Table 2-4-2 shows the oil and greases used with the set.

1) Oiling should be performed periodically. Oil the shafts byreferring to the maintenance table.

2) After replacing a part, grease the required points. For theparts to be greased see the exploded diagram in chapter 5,“DISASSEMBLY DRAWINGS AND PARTS LIST”.

3) As Hanal separates over time, be sure to mix it (shake) wellbefore use.

4) Take care not to leave grease or oil on the tape transportparts which come into contact with the tape or on the brakepads.

5) Take care not to apply too much oil or grease. The standardoiling quantity is one drop and the standard greasing quan-tity is the quantity with which the grease does not overflow.

2.4.3 Cleaning

The mechanism incorporates a video head cleaner that is effec-tive for the removal of magnetic dust, etc. However, tape lubri-cant adhering to the head surface produces a spacing loss, it isrecommended to polish the heads using a head cleaning tape.When the video heads become soiled an increase in the errorrate results. Eventually, when the error rate increase is too muchto be corrected by the error correction circuit, block noise willbe observed in the picture.

1) Cleaning the video headsUse the DVC cleaning cassette for cleaning the video heads.Always be sure to use the cleaning cassette, Part No. M-DV12CLAUX.The video heads should be cleaned periodically. Moreover,care should be taken about the operating environment asthe tape running time standard varies accordingly. Pleaserefer to “Precautions for Use of Head Cleaning Tape” in theinstructions.

Caution

As the DVC cleaning tape has a much higher lap-

ping effect than VHS cleaning tapes, frequent use

of the DVC cleaning tape will reduce the head serv-

ice life. Do not play the DVC cleaning tape for more

than 10 seconds per run or for more than 4 times

per cleaning session.

The cleaning tape can be used effectively for up to

about 4 passes. It cannot improve the cleaning ef-

fect even if it is run for more than 4 times.

2) Cleaning the upper/lower drumsUse a cleaning cloth or high-quality paper sheet to clean theupper drum. Moisten the cloth or paper sheet with a smallamount of ethyl alcohol, apply it lightly against the upperdrum while turning it by hand.After this operation, wipe it with a dry cloth or paper sheetwithout alcohol. Be sure to play the cleaning tape to its end.The lower drum tends to gather magnetic dust, etc. in itslead section, and linearity cannot be achieved if this becomesexcessively dirty. The tape inlet and outlet areas are con-taminated particularly easily, causing trouble such as drop-out in FM signal reproduction, block noise on one side of amonitored picture, absence of audio output or incapability oftime code readout. To clean the lead section, use a tooth-pick and rub lightly along the lead section. Be careful not toscratch the video head when this is done.

Fig. 2-4-1

3) Cleaning the tape transport systemMoisten the tip of a cotton swab with alcohol and use it toclean the tape transport parts. Take special care of the TU/SUP guide roller flanges and the rear sides of the inclinedpoles, as these are the parts that most frequently collectmagnetic dust.

Caution

Do not wipe the capstan shafts using alcohol. Other-

wise, the oil in the bearings may be diluted by the

alcohol and become attached to the tape.

REPLACING SURFACE MOUNT “CHIP” COMPONENTS

• Some resistors, shorting jumpers (0 resistance), ceramiccapacitors, transistors, and diodes are chip parts. These chipparts cannot be reused after they are once removed.

• Chip resistors used in some circuits are of high precisiontype having little error in resistance.To demonstrate the full capacity of this set, place an orderfor proper parts referring to the diagrams and parts lists inthe section 5.

• Soldering cautions:1) Do not apply heat for more than 3 seconds.2) Avoid using a rubbing stroke when soldering.3) Discard removed chips; do not reuse them.4) Supplementary cementing is not required.5) Use care not to scratch or otherwise damage the chips.

DESCRIPTION OF CIRCUITRY

8.1 CAMERA BLOCK CIRCUIT DESCRIPTION

8.1.1 IS board

The CCDs of 1/3" IT, 380,000-pixel (NTSC), 440,000-pixel (PAL)CCDs. Vsub is adjustment-free.ISB, ISG and ISR are connected through FPCs, which cannot bedisconnected from the circuit boards.The CCDs are soldered directly onto the board. Therefore, sol-dering should be removed when replacing the CCD block as-sembly.

Fig. 8-1-1

The S/H circuit, which in the previous models has been locatedon the IS board, is located in the AFE block on the Main boardthat is located after the IS board. This has resulted in a simplifi-cation of the IS board.

The main block can be divided into the three functional compo-nents of the AFE, PLD and DBE blocks.(1) AFE (Analog Front End) block

IC501, 502 and 503 are the CCD signal processor ICs. Theyperform S/H, AGC and A/D conversions. It converts the ana-log output signals from the CCDs (pixel charge signals) into12-bit digital signals and outputs them. The handling dynamicrange is 400%.ICs 504, 505 and 506 form the V-driver circuit, which sup-plies the vertical drive pulses to the CCDs.

(2) PLD (Program Logic Driver) blockIC561 is the PLD IC, which can be divided functionally intothe AFE-IF, TG, CLK-CTL, ZEBRA-ZONE, DV-REC-IF and DV-PB-IF sections.

1 AFE-IF:The 12-bit RGB digital signals output from the AFE blockare input to the MUX (multiplexer) in this section andoutput to the DBE block by sequential switching usingthe 3x clock (52 MHz). At the same time, this sectionalso generates the Y(AFY) signal for use in the lensautofocusing from the RGB signals, and output the Y(AFY)signal to the lens.The LINE REVERSE circuitry inverts (by mirror image in-version) the Bch signal, which has been inverted by thegapless prism (see section 8.2, “New prism optics”) toreturn it to the normal signal.

2 TG (Timing Generator):This section generates the H-drive pulse and sends it tothe CCDs through ICs 510 and 512 in the AFE block.

3 CLK-CTL:This section switches the 2x and 3x clocks, used in sig-nal processing, based on the 14 MHz reference clock.

4 ZEBRA-ZONE:This section outputs the zebra signal for use in displayon the LCD monitor and viewfinder.

5 DV-REC-IF:The DV-Y (8-bit) and DV-C (8-bit) signals, which are out-put from the DV/IF circuit in IC621 in the DBE block us-

Fig. 8-1-3

ing the 27 MHz clock, are input to the LPF & Down-sam-pling circuit and output from it at 13.5 MHz. This signal isthe Data Formatter (DV) signal. It is output in 4-bit widthsby switching the LSB (4-bit) and MSB (4-bit) using the 2xclock (Fig. 8-1-3), and the signals obtained by this are the4-bit Y and C (Cb/Cr) signals. These signals are sent tothe VCR as the recorded signals.The COLOR-BAR-GEN circuit generates the color bar sig-nal for use in recording. Apart from this, the color bar sig-nal displayed on the LCD monitor and VIDEO output isgenerated by the encoder circuit in the DBE IC (IC621).When “BARS” is selected, both of the color bar signalsare switched ON.

6 DV-PB-IF:The 27 MHz, 4-bit wide Y and C (Cb/Cr) playback signalsfrom the VCR are input to the Data Formatter (DV) cir-cuit, and output as the DV signals including Y: 13.5 MHz,Cb: 6.75 MHz and Cr: 6.75 MHz (this is the reverse op-eration to 5).The Data Formatter (DVE) converts the Y/Cb/Cr signalsrespectively into 8-bit signals, switches them using the3x clock in MUX and sends them to the DBE blockthrough the PB switch. As the interface to the DBE blockhas a width of 12 bits, the signal width is adjusted byadding 4 bits (all “0”) at the top of each 8-bit signal.

sideration of the ease of signal processing and rate con-version, it is more convenient to handle the RGB signalsat the same timing. Therefore, their timing is returned tothe same timing in an early stage in the DSP. It is also inthis stage that the 14 MHz sampled RGB signals areoversampled for their processing in 28 MHz.

d) RGB gamma circuit“RGB Gamma” compresses the dynamic range of thesignals while they are still in the RGB format. The RGBsignals change from 12-bit to 10-bit signals from the out-put of this circuit.The gamma processing method is the “table method”in place of the “polygonal line approximation Method”.The “table method” is also adopted in other circuits suchas “Detail” and “Y-Gamma”. The table data for use inthe processing is handed from the camera’s CPU to theDMA block in the DSP.

e) Y/Cb/Cr conversionThe signals that have been in the RGB format until “RGBGamma” are converted into the Y/Cb/Cr format in thiscircuit block. However, the sampling rate is still 28 MHz(4:4:4) at this stage.

f) Y-gamma processing blockThis circuit block applies gamma processing to the Y signal,which changes from a 10-bit to an 8-bit signal in this stage.(The Cb/Cr signals are still 10-bit signals in this stage.)

(3) DBE (Digital Back End) block1 Circuit blocks in the DBE IC (IC621):

IC621 is composed of the camera DSP and mainly han-dles camera process signals. The DSP IC is adopted forthe first time with this model. Its internal functions areas described below.

a) Input signalsThe 12-bit RGB digital signals, obtained by A/D conversion inthe AFE block, are input to the PLD (IC561), rearranged (us-ing the 3x clock) by the internal MUX (multiplexer) and sentto the DSP.

b) White blemish compensationThis is the first circuit block that the input signals enter.The pixels are corrected in real time “Blemish Compen-sation” in the figure and the blemish is detected by“Blemish Detect” in the next stage.The position data of the detected blemish is stored in-side the EEPROM (IC406), loaded every time the poweris turned on and applied as a correction by “Blemish Com-pensation”.

c) Shifted pixel correctionTo prevent false signals and in consideration of the pro-duction tools, the CCDs are bonded by adopting the 1/2pixel shifting technique. However, the VCR of DVC (4:1:1/NTSC, 4:2:0/PAL ) digital camcorders do not need as highsignal resolution as multipurpose cameras. Also in con-

g) 4:4:4 → 4:2:2 conversionThis circuit block converts the Cb/Cr signals from 14 MHzto 7 MHz (4:4:4 → 4:2:2) and from 10-bit to 8-bit signals.

h) Rate conversion blockWhile the signals have been processed based on the 14MHz and 18 MHz sampling clock rates, this circuit blockconverts them into 27 MHz-based signals.

i) EncoderAfter completion of the camera input signal processing,the signals are divided into those for use by the mainrecording circuitry (those sent to the DVC VCR) and thosefor use by the LCD monitor.This circuit block generates the composite signal usingthe NTSC/PAL timing generator and digital encoder inthe DSP.It is also in this circuit block that the sync signal is added.However, as simple addition of the sync signal causesthe number of bits assigned to the effective video to bereduced, the total number of signal bits is increased to10 bits at the time of sync addition.

(4) Other circuits1 Input to the KA-DV300 network pack:

The input signals from the VCR (PLAYBACK or EE) arebranched on the Main board and output to the KA-DV300based on the drive by ICs 565 and 567. As a result, boththe recorded EE signals and playback signals can be con-verted into MPEG4 by the KA-DV300.

In consequence, the D/A block for the analog output em-ploys a 10-bit encoder.This circuit block also generates the color bar signal foruse in display on the LCD monitor and the viewfinder(the color bar signal for recording is generated in the PLCIC (IC561)).

j) DMA blockThis circuit block mainly handles the data exchange withthe camera CPU and the storage of DSP parameters (ta-ble data).

2 Analog video amplifier:IC625 is the analog video amp. It generates the compos-ite signal and the Y/C signals from the analog Y/C sig-nals, which are output from the encoder of the DBE IC(IC621), and outputs them at the connectors. For the sig-nal level adjustments, the DBE IC adjusts the overall Ysignal level and the analog video amp adjusts the C sig-nal level.

As the use of gap-less prism optics results in the impossibil-ity of reflections from the opposite directions inside the prismoptics, the Bch signal is reflected only once (In the previousprism optic systems, a signal corresponding to Rch was re-flected twice by the internal prisms. See Figure 8-2-1). Thismakes the Bch image an inverted one (the left and right ofwhich are inverted like a mirror image). To deal with this, theBch video signal from the CCD is inverted (returned to a

8.2 NEW PRISM OPTICS

The GY-DV300 adopts a new, 1/3" three-CCD prism optics(gapless prism technique) featuring a compact size and lightweight. The new prism optics incorporates new technologiesthat are different from those used in previous models.

(1) Gapless prismsThe light is divided into the three primary colors of light, R, Gand B, by the combination of three color-spectral prisms.Each of these prisms has special surface treatment to re-flect the light of specific wavelengths. These prisms havebeen bonded by reserving air gaps of 2/1000 mm in order toreflect the light using these air gaps. However, the difficultyin combining the prisms by providing these gaps uniformlyand in parallel has become a factor for increasing the pro-duction costs.But the new gapless prism technique makes it possible tocombine the prisms without leaving the air gaps. This hasimproved productivity and decreased the production costs.As this technique also allows the prism size to be reduced,it contributes to a reduction in both size and costs.

Previous prism optics

New gapless prism optics

Fig. 8-2-2 Parts Required in Previous Bonding Techniques

On the other hand, the direct bonding technique of the newoptics bonds the CCD packages and prisms directly using aspecial adhesive agent that hardens under the irradiation ofUV rays. Because of this property, the adhesive agent doesnot harden at the register alignment stage but is hardenedwhen the UV rays are irradiated after the alignment. Theadhesive agent can be used to bond the ceramic-made CCDpackages and glass-made prisms without additional metal-lic parts. This feature makes it possible to implement thewhole CCD block featuring a compact size and a light weight.However, the use of an adhesive agent for bonding the CCDsmakes it impossible to peel the CCDs once they are fixed. Incase of CCD trouble, it is not possible to replace only thefaulty CCD. As a result, the CCD block of this model cannotbe serviced even at the factory. If CCD faults are discoveredduring a store servicing, the whole CCD block assemblyshould be replaced.

normal image) by an electrical circuit. In addition, the arrangement of the RGB colors of the new optics is also differentfrom the previous optics.

(2) Direct bondingPrevious optics attached the CCDs to the prisms by meansof sheet metal soldering technique (solder bonding). As theCCD packages themselves are not made of a soldering-com-patible material (or treatment), each CCD had to be fixed ona sheet metal plate (made of soldering-compatible metallicmaterial), which was then soldered on the soldering section(copper-plated area) of the prism optics. With this technique,the CCDs can be replaced individually because they can beremoved easily by melting the solder. (Nevertheless, bond-ing is possible only in the production line because it requiresspecial tools and technologies for achieving register accu-racy of the micrometric order.)The disadvantages of the previous optics included high costsdue to an increase in the number of parts, such as the sheetmetal plates used in the soldering process. An increase inthe CCD block size for incorporating these parts was also aproblem.

8.3 LENS CONTROL SYSTEM

OutlineThe lens assembly used with this model incorporates automaticcontrol functions such as autofocusing and OIS (Optical ImageStabilizer) in addition to the auto iris control that has also beenavailable with previous model. In order to provide compatibilitywith them, the Lens CPU (IC905 on the Main board) is providedfor exclusive use in the lens control. This chapter gives a de-scription of this control system.

(1) Autofocusing controlIn general, autofocusing is performed by adopting one ofthe following three techniques.1) Active autofocusing:

Triangulation using IR rays or ultrasound waves2) Passive autofocusing:

Phase error detection using an optical focus sensor.3) TTL (Through The Lens) autofocusing

Electrical signal processing of an image incident throughthe lens

The autofocusing of the lens in this model is controlled withthe TTL method.

The video signals obtained from the three RGB CCDs are A/D converted and input to the PLD (IC561) in the digital signalprocessor block.The PLD generates the 9-bit Y signal for use in autofocusing(AFY) apart from the processing of the signals to be sup-plied to the main camcorder circuitry.The AFY signal data is subjected to the internal computationby the autofocusing DSP (IC906) and the results are sent tothe lens CPU.The lens CPU outputs the data as serial data to the focus/zoom driver IC (IC901) to drive the focusing motor of thelens using the DC voltages output from the D/A output ports.The factors deciding the autofocusing effect is the compu-tation inside the DSP and the program processed by thelens CPU.

Autofocusing control consists of moving the focusing lens alittle beyond the AFY modulation peak and then returning itslightly so that the focusing lens stops at the peak position.The modulation peak point is defined as the optimum focuspoint. Due to the principles themselves, focusing may some-times be difficult when the object has little contrast.

It goes beyond the peak, goes back to the peak and stops there.

(2) OIS (Optical Image Stabilizer) controlThe lens of this model incorporates the OIS function for cor-recting blurring due to a slight movement of the hands. Theoptical correction employs the shifting technique, the detailof which is described in section 8.4. This section deals onlywith the flow of control signals.Blurring is detected via the information from the gyro sen-sors provided on the lens. Two gyro sensors for horizontaland vertical directions are used to detect the lens blurringdirections. The information output from the gyro sensors isinput to the CAM CPU circuit block on the Main board. Thiscircuit block obtains information such as the displacementand velocity (acceleration) of the lens, detects the blurringsituation based on it, and sends the result signals (GYRO_X,GYRO_Y) to the lens CPU. The CPU performs software-basedcomputations of the optimum correction amount based onthe obtained information and outputs the results to the OISD/A driver IC (IC902) (serial data).The OIS driver IC (IC902) outputs the pulse signal for drivingthe motor of the blurring correction shift lens.One of the important factors deciding the effects of OIS isthe software program. We have performed a large numberof experiments to investigate this point, and the best possi-ble correction program has been developed and incorporatedin the CPU.

(3) Countermeasures against MalfunctionsWith both autofocusing and OIS control, the key is the dig-ital data and the software program incorporated in the lensCPU. Even when the signal lines can be observed in servic-ing, it is difficult to analyze the operations. When analyzingmalfunctions in stores, one should observe the changes inthe analog signals (including voltage) at the input from andthe output to the lens.CN901 is the point of concentration of all information ex-changes between the lens and Main board. To check theoperations and determine their availability, it is necessary toobserve the signal pins of this connector.However, note that the lens is an assembly part. This meansthat it should be replaced as a whole assembly except forsome parts.

Fig. 8-4-1 Electronic Image Stabilizer System

(In Cases when Camera Shake Occurs)

(3) Optical image stabilizerThe optical image stabilizer device is more complicated thanthe electronic image stabilizer device. However, the advan-tage of the optical technique, which is the absence of reso-lution degradation causes the technique to be applied in high-end type consumer-oriented camcorders as well as inhandheld professional camcorders.

When the camera (the whole camera including the lens) isdeviated from the intended light axis due to a slight move-ment of the hand, optical image stabilizer corrects the lightaxis error optically using the lens. Its correction method canroughly be divided into “shift correction” and VAP (Vari-An-gle Prism)” methods.

The lens used with the GY-DV300 incorporates the opticalimage stabilizer system of the shift correction type.

The shift type image stabilizer corrects the light axis errorfrom the object due to slight movements of hands by dis-placing the position of the built-in correction optics. It is calledthe shift type technique because it shifts the correction op-tics in the up-down and left-right directions.

Image without correction Image after correction

Entire effective image area of CCD

Area usually usedAssuming that the camera is vibrated toward the bottom left of the object, the area capturing the object accurately in the entire imaging area of the CCDs is only the area shown by this figure. Therefore, this area is trimmed and enlarged to correct the image stabilization due to any slight shake of the camera.

The center area of the CCD imaging area is used when camera shake does not occur.Write of the entire image in memory

Trimming and readout

If camera shake occurs, the image data of the area to be corrected is trimmed and enlarged.

8.4 CONCEPT OF IMAGE STABILIZER SYSTEM

8.4.1 Image stabilizer system function

The new lens assembly used in this model incorporates an op-tical image stabilizer system. Compared to the electronic imagestabilizer system used frequently in other camcorders that arecommercially available, the system is better suited to lessenthe video quality degradation and is therefore suitable for pro-fessional applications. In the following, the differences betweenelectronic and optical image stabilizer and models of correctionmethod will be described.

(1) Comparison table of electronic and optical techniques

Electronic OpticalCost Low High

Mainapplications

(2) Electronic image stabilizerIn general, electronic image stabilizer loads the video sig-nals from the CCDs into memory, compares the current andthe next images and determines whether the camera ispanned/tilted or has been shaken by assessing the qualityof the image. This technique trims the image area to be used(the image containing the intended object) from the originalimage that is captured in a larger size than required. (This ispossible because the CCDs receive the images through thelight reflected from their whole surface). The enlarged im-age is then output (because the trimmed image is slightlysmaller than required).As a result, the image resolution may be degraded slightlycompared to that of the image before trimming.

Thanks to the implementation of corrections using an elec-tronic circuit and control software without the need of ex-pensive, optically complex devices, this technique featureslow cost and compact size, which makes it suitable for usein consumer-oriented camcorders.

Resolution is degradedbecause trimmedimages are enlarged inthe display.Suitable for compactconsumer camcorders.

Little degradation inresolution thanks tooptical correctioninside the lens.Suitable for profes-sional camcorders.

Fig. 8-4-2 Concept of Shift Correction

For instance, when the lens (and the whole camera) is ori-ented downward by a slight movement of the hands, anerror of the light axis from the object causes the image atthe CCD input to be deviated downward. In this case, thecorrection optics should be shifted downward to refract thelight for returning the object image to the intended position(center). As slight movements in the actual camera opera-tion occur both in the up-down and left-right directions, thecorrection optics should be shifted in parallel in all of the up-down and left-right directions on a plane that is orthogonalto the light axis.

Fig. 8-4-5 Operation When Camera Shake Occurs

When the optics (including the camera) is tilted, the lightaxis is corrected by controlling the prism so that the bellowsstructure is varied and the light axis is refracted in the de-sired direction as shown in Fig. 8-4-5.

The advantage that the VAP method presents is that it doesnot require the space for allowing the correction optics shift-ing (space for the up-down and left-right shifting).It is said that the correction effects of the shift and VAP meth-ods are almost identical. In consequence, they are usuallyselected according to the type of the lenses (optics) in use.

As described above, the optical image stabilizer method cor-rects the light axis errors by refraction in the optical lenses(in a manner than can be called an analog correction). Thus itcan deal with slight movements of a wide range of frequen-cies and uses the entire optical image received by the CCDswithout quality degradation. It is therefore regarded to besuitable for use in professional-oriented cameras.

Fig. 8-4-4 Cross-Section of a Vari-Angle Prism

Fig. 8-4-3

Electronic image stabilizer detects camera shake fromchanges (correlations) in the images written in memory, de-termining the movement direction, movement amount andwhether each change is due to a slight movement of thehands or panning/tilting of the camera. Meanwhile, opticalimage stabilizer uses gyro sensors incorporated in the lensand corrects the changes in the X/Y directions of the imageby controlling two motors for shifting the correction lensesbased on the direction and acceleration information obtainedfrom the gyro sensors.

Another optical correction method, though not employed inthe GY-DV300, is the VAP method. While the shift correc-tion refracts the light axis by shifting the correction optics(lenses), this method refracts and modifies the light axis using

a prism that can vary the refraction direction by varying itsown thickness (vari-angle prism).

The prism thickness is changed instantaneously by a vari-angle prism, in which two sheets of glass are connected bya bellows made of a special film and a high-refractivity fluidis contained inside it.

8.5.3 Correction

At the moment power is turned on, the blemish position datastored in the EEPROM (IC406) is sent to the blemish correctionblock in the DSP through the SD RAM (IC622) for real-time blem-ish correction.Since blemish correction is performed in the LoLux mode, cor-rection is always applied on a per-pair basis covering two pixelsat a time.As shown in Fig. 8.5.3, for the pixel with blemish (P2) and theadjacent one located at its left or right, the average value of thepixels two positions down of each pixel is calculated and ap-plied as the correction signal to each pixel.

8.5 BLEMISH COMPENSATION

8.5.1 Outline

The GY-DV300 adopts a new blemish compensation techniqueto improve the correction accuracy.This function corrects blemish (spots caused by high signal lev-els) produced in CCDs in a digitally, using a memory. This func-tion is used only after replacement of the optical block assem-bly or when a CCD produces new blemish, and is not used usu-ally. Detection of the blemish to be corrected can be performedusing a service menu (see section 1.8).

8.5.2 Detection

Blemish is detected by the DSP (IC621) and PLD (IC561) on theMain board.A pixel on which blemish is produced outputs the signal evenwhen no light is irradiated on it (dark current) so the level of thecorresponding area becomes permanently high. The DSP setsa detection level and corrects the blemish exceeding that level.The maximum number of correctable blemish errors is 32 in-cluding all of the RGB channels (16 in the case where there ismore than one on a single line). Blemish with composite outputlevels higher than 50 mV is corrected in priority.When the detected number exceeds 32, blemish detection isperformed again by setting a higher detection level.The detected positions are reset every time detection is per-formed (ERROR DETECT EXECUTE). The blemish position datais stored in the SDRAM in the DSP and the CPU read in it andstored in the EEPROM (IC406). The CPU sends the addressdata of the positions to the DSP every time the power is turnedon.The blemish detection area is equal to the effective video pixelarea but 8 pixels on the left and right are not corrected with anyline. The correction effect is reduced in the case of successiveblemish (blemish errors on adjacent pixels).

Caution

The camera enters the LoLux mode and the lens iris is forcedto close during detection. If the iris is not closed and light isincident on the CCDs, the message “LENS NOT CLOSED ?”is displayed on the LCD or viewfinder screen and the opera-tion terminates in a detection error.

After addi-tion of error correction codes to all of these signals, they arecoded for tape formatting and recording, and sent as theREC data to the PRE-REC processor (IC1).In tape playback, the played analog signal is input from thePRE-REC amp (IC1) and supplied via the A/D, waveformequalizer, clock reproduction, Viterbi decoding, and then goesthrough the error correction circuits to output the video, au-dio, sub-code, and AUX data. This DSP also has a built-inIEEE1394 bus.The DVC DSP (JCY0176) is composed of the following blocks.Its block diagram is shown in Fig. 8-6-3.

8.6.3 Audio Circuitry

(1) Signal flowThe input microphone signals include the MIC1, MIC2 andbuilt-in MIC. The reference input level of MIC1/MIC2 is -56dBs and built-in MIC is -40 dBs. The MIC1 and MIC2 inputsare phantom microphone compatible so that +48 V DC canbe supplied. The MIC signal inputs are sent to amplifiers forlevel boosting to -25 dB. Then, the built-in MIC and MIC1are input to IC708 to be selected. After this, the signal issent through the channel switch IC708 and input to ALC/VRs 701 and 702. VRs 701 and 702 are audio recording levelcontrols that are effective in Manual mode. ICs 706 and 707are the ALC circuit that are effective in Auto mode. The sig-nal is then sent through the ATT for level attenuation to -32dB, and input to pins 54 and 59 of IC711 (AK4560AVQ), whichamplifies the signal to the reference recording level of -12dB. The signal is then A/D converted and output at pin 29 tobecome the REC DATA signal.In playback, the digital data is input from pin 30, D/A con-verted and output at pins 19 and 21. The signal is then am-plified from -12 dB to -8 dB before going to the camera out-put terminal.IC711 uses MCLK, LRCLK and BCLK as clocks. They are notsynchronized with the video signal so the GY-DV300 doesnot have the audio lock function.

The color filters are coded in a delta arrengement. Theareas masked in the figure are not displayed.

2 Description of LCD panel Operatins• A vertical driver, which consists of vertical shift regis-

ters, enable-gates and buffers, applies a selected pulseto each of 228 line electrodes sequentially one line elec-trode at a time in a single horizontal scanning period.

• The selected pulse is output when the enable pin goesto high level. PAL signal pulse elimination display and16:9 mode pulse elimination display are possibly by us-ing the enable pin and simultaneously controlling VCK.

• A horizontal driver, which consists of horizontal shiftregisters, gates and CMOS sample-and-hold circuitry,applies selected pulses to each of 880 signal electrodessequentially in a single horizontal scanning period.These pulses are used to supply the sampled videosignal to the row signal lines.

• The scanning direction of the horizontal shift registerscan be switched with the RGT pin. The scanning direc-tion is left to right (right scan) for RGT pin at high level(2.6 to 5.5 V), and right to left (left scan) for RGT pin at

low level (0 V). In addition, the scanning direction ofthe vertical shift registers can be switched with theDWN pin. The scanning direction is top to bottom forDWN pin at high level (2.6 to 5.5 V), and bottom to topfor DWN pin at low level (0 V). (These scanning direc-tions are from a front view.)

• The vertical and horizontal drivers address one pixel,and then thin film transistors (TFTs ; two TFTs for onepixel) turn on to apply a video signal to the pixel. Thesame procedures lead to the entire 228 x 880 pixels todisplay a picture in a signal vertical scanning period.

• Pixel are arranged in a delta pattern, where sets ofRGB pixels are positioned shifted by 1.5 dots againstadjacent horizontal lines. The horizontal driver outputpulse must be shifted by 1.5 dots for each horizontalline against the horizontal sync signal to apply a videosignal to each pixel properly.

• The video signal is input with the polarity-inverted everyhorizontal cycle.

8.8.2 LCD viewfinder

(1) OutlineThe LCD viewfinder is an active matrix panel with a diagonalsize of 1.1 cm incorporating built-in drivers, which are madeusing polycrystalline silicon thin film transistors. It is capableof full-color display in both NTSC and PAL formats. It em-ploys the delta array and provides even pictures, which donot present fixed color patterns as in the other arrangementsthat use the vertical stripe and mosaic arrangements.

Features

• 180,000 display dots, diagonal size 1.115 cm (0.44”)• Horizontal resolution 400 lines• Light transmittance 4.0% (typical)• High contrast ratio of 200 (typical) thanks to the normally

white mode• H and V drivers built in (with input level converter circuit,

TTL drive possible)• Smooth picture thanks to the RGB delta array• Full-color display• NTSC/PAL compatibility• 4:3 and 16:9 aspect ratio switching function• LCD VF has Up-down and left-right inverted display func-

tion. Those functions, however, are not used with GY-DV300.

Device structure

• Number of pixelsTotal number of dots: 827(H) x 228(V) = 188,556Number of display dots: 800(H) x 225(V) = 180,000

• Active matrix panel with built-in drivers, usingpolycrystalline silicon thin-film transistors
