I. BASIC OPERATION

A. Functions

The scanner functions are divided into the following three main systems.

1. Optical System

The optical system consists of the scanning lamp, lens and mirrors. It exposes a document,

then the reflected light from the document is collected onto a light-sensitive device CCD

(charge-coupled device ) via the lens and mirrors.

2. Image Processing System

The image processing system consists mainly of the CCD, analog IC, and ASIC. It converts

analog signals from the CCD into digital signals, which is read by the host computer.

3. Control System

The control system consists mainly of ASIC, USB controller, CPU, and motor driver. The CPU

controls the whole scanning operation. The USB controller controls the interface between the

CPU and ASIC, while the CPU interprets all commands from the host computer.

image processing of the scanner. The image signals read by the CCD are converted into digital

data by analog IC. The digital data are then processed by the ASIC and output to the host

computer via USB interface.

A. Scanning Lamp

When the scanner is powered on, the scanning lamp lights to standby. The scanner is

provided with an energy saving setting which is made in the Scanner Utilities Dialog. For

example, if it is set for 30 minutes, then no scan command is sent for 30 minutes, ASIC sends

the scanning lamp off signal to turn off the lamp.

When the host computer sends a command to change scaling/resolution, the motor driver

current control signals [PA+, PA-, PB+, PB-] are changed to generate a torque for the rotating

speed. Yet, the reverse speed of the scanning unit is always constant.

The ASIC receives each command sent from the host computer via the USB interface to

control the motor by four-phase motor driver pulse signals [OUT1B, OUT1A, OUT2A, OUT2B].

1. Analog IC

Output signal from the CCD is an analog signal which cannot be used as image data. So

RGB output signal from the CCD is amplified by analog amplifier to generate analog data. The

generated data is converted into averaged analog signal by D/A converter, then got feedback to

the A/D converter to output constant digital data to the ASIC.

2. D/A Converter

D/A converter removes ununiform analog data generated by the CCD. It adjusts CCD output

to keep max. 5V of input signal to the A/D converter, to make the black level of the image

constant.

3. A/D Converter

The A/D converter converts the black-level-corrected image signal (analog signal) to a 14-bit

image data (digital signal) in the order of red, green and blue image signal.

5V is applied to the VRT terminal and reference voltage is applied to the VRB terminal. A/D

converter outputs 0 when input signal is 5V, and outputs 16383 when input signal is

reference voltage. This converts 1 pixel signal into the image data of 16384 gradations for red,

green and blue each.

Figure 2-11


32/102

CHAPTER 2


C. Calibration

Calibration can be performed to normalize the pixels of a linear CCD so that each pixel

produces the same digital output code from the scanner when presented with the same image

light intensity. This intensity ranges from black (no light) to white (maximum light intensity).

The CCDs analog output may have large pixel-to-pixel variations in their output voltage when

scanning the same white image (corresponding to errors on brighter signals). If these offsets

are subtracted from each pixel, and each pixel is given the optimum gain setting to correct for

different efficiencies, then these errors can be eliminated.

Ideally the digital output code for any pixel would be zero for a black image, and some code

near the full scale for an image with maximum brightness. This code is called the target code.

The analog IC eliminates these global and pixel-to-pixel offset and gain errors with its

Correlated Double Sampling, Offset D/A converter, Variable Gain Amplifier (VGA), and

Programmable Gain Amplifier (PGA).

Calibrating an analog IC-based system requires three steps:

1) Offset Calibration

Takes a black image and normalizes the digital output code for each pixel to a code at or near

0.

2) Boot-Gain/Coarse-Gain Stage Calibration

Finds the optimum gain setting that places the output voltage of all the pixels from x0.93 to

x9 adjustment range of these two stages.

3) Shading Correction from ASIC

Calculates the gain required for normalizing the output of each pixel to the target code.

D. Filter Processing

When converting resolution and scaling, the image quality tends to be reduced. To prevent

the image quality reduction, filter processing is performed according to the resolution. Filter

processing for this scanner includes horizontal scanning interpolation, vertical scanning

interpolation, descreen, and averaging. Table 2-2 shows the resolution for filter processing.

E. Interpolation Processing

When reading images at higher resolution, the one pixel output of the CCD is treated as two

image data in the horizontal scanning direction, and the one line output of the CCD is treated

as two image data in the vertical scanning direction, causing a reduced image quality. To

prevent the image quality reduction, interpolation processing is performed. Figure 2-12 shows

a change in image density by the interpolation processing.

F. Averaging

When reading images at lower resolution, the thinned data increases resulting in output

image deterioration. Averaging is a process in which the data to be thinned and the data to be

actually output are averaged and output, in order to suppress the image deterioration due to

the data thinning.

V. INTERFACE


Since early 1997, the Universal Serial Bus (USB) has been the standard on most PCs. TheUSB standard was developed by Compaq, IBM, Intel, Microsoft, NEC, and Northern Telecom. It

resulted from an industry-wide initiative to standardize peripheral attachments to PCs, and to

improve the speed, performance and ease of use of PC peripherals.

USB has been supported from Windows 95 (OSR 2.1), and it is now a key component of

Windows 98. In addition, USB are supported in Windows CE and Windows 2000 according to

Microsoft. USB support is currently available on the Apple platform and will be available

shortly on some other platforms.


1. True Plug & Play

Unlike the previous generation of SCSI scanners, no add-in cards are required to setup the

USB scanners. This eliminates complex procedures, such as opening the box to install a card,

or reconfiguring the system (setting DMA, IRQ, jumper cables, etc.) The USB scanners are

simply plugged in and unplugged at any time.

2. Higher Speed

USB scanner is nearly 10 times faster than a standard parallel-port scanner at bandwidth 12

Mbits/sec.

3. Multiple Devices Support

USB specification can support up to 127 devices simultaneously on a computer by using

hub terminals as additional plug-in locations.

VI. POWER SUPPLY

DC power is supplied from a supplied AC adapter. Through power regulator, three DC power

sources (+5V, +12V and +15V) are used in the circuit. +5V is supplied for the digital circuit

and linear chip, +15V is for the CCD PCB, and +12V is for the motor driver and scanning lamp.Protection circuit is used between the AC adapter and regulator to prevent over voltage, over

current or reverse polarity.

CHAPTER 5


I. INTRODUCTION

A. Initial Check

Check if the operating environment conforms to the following conditions.

* Line voltage is within 10% of the rated value.

* Ambient temperature and humidity conform to the operating environment. (Refer to

CHAPTER 1, I. SPECIFICATIONS)

* The scanner is not setup near a water faucet, boiler, humidifier, open flame, or in dusty

place.

* The scanner is not exposed to direct sunlight. If it is inevitable to setup in a sunny place,

hang a curtain to block direct sunlight.

* The scanner is setup in a well-ventilated place.

B. Others

Moving a scanner from a cold place to a warm place can cause condensation on the metal

parts, resulting in a faulty operation.

* Scan count

Set a number from 1 to 100.

* Resolution (dpi)

When the resolution for scanning an image is selected at 200, 300, 400, or 600 dpi, whole

document glass area is scanned. When selected at 1200 dpi, 10,280 pixel x 500 pixel area in

the upper side of the document glass is scanned.

* Image handling

When Read in memory (no file) is selected, the image is read into the memory, then

abandoned after readout. When Save to TIFF file is selected for handling an scanned image,

the file of img0.tif is saved in the folder of the Canon Scanner Test. When scan count is setat 2 or more, the file of img0.tif, img1.tif, img2.tif ... are saved.

File space to be saved is as follows.

200 dpi : 11.3 MB

300 dpi : 25.6 MB

400 dpi : 45.5 MB

600 dpi : 102.4 MB

1200 dpi : 14.6 MB

Note : Confirm before scanning that the available disk space on the HDD in which theCanon Scanner Test is installed exceeds above file space.
