VIVID PICTURE
• PIXEL DENSITY AND PPI
• RESOLUTIONS

PIXEL
• DEFINITION-In digital imaging,a pixel is a smallest controllable elements of a picture (Building block of a picture).
• PIXEL DENSITY-Number of pixels in certain space.Usually measured in PPI.
• PPI(Pixel Per Inch)-Number of pixel per inch.

RESOLUTION
• DEFINITION-Number of distinct pixels in each dimention that can be displayed.
• AVAILABLE RESOLUTIONS- *2K *4K *8K

WORKING
15
• INCIDENT LIGHT IS SEPARATED INTO FOUR COLOR AND DIVIDED IN TO….• TWO GREEN, ONE RED, AND ONE BLUE (GGRB).• THREE-SENSOR IMAGING SYSTEM (RGB) USED IN COMMERCIAL AND BROADCAST VIDEO CAMERAS.• PRISM FOR THE FOUR-SENSOR SYSTEM CAN BE MADE AS SMALL AS THE CONVENTIONAL RGB PRISM.
Structure of the color separation prism developed for the four- sensor imaging system.

8K APPLICATIONS: TELEMEDICINE
*Recording of surgeries and medical diagnostic processes for educational purposes
-Transmissions during symposiums and conferences-High quality materials for medicine students

.
8K APPLICATIONS: SECURITY AND MONITORING
issue: face recognition in a crowd at airports, train stations and during mass events (e.g.
stadiums)
Many details on single 8K frame – the powerful source for image processing
Useful for police, border services and others security units
Constraints:
scalability,
processing

8K APPLICATIONS: CAD/CAM PROJECTS
Automotive designDesign and digital visualisation of 3D car modelsTests of safety, aerodynamics and ergonomic solutions
Architecture and urban planningDesign and visualisation of buildings and engineering constructions modelsTests of ergonomic and functionality as well as strength and safety of constructions

4K LIVE TECHNOLOGY, VIDEOCONFERENCINGAND BROADCASTING
4K/8K Public Screening

8K APPLICATIONS: VISUALISATION OF SCIENTIFIC PROCESSES
High resolution images in science:Physicis – visualisation of research on elementary particles and quantum mechanicsBiochemistry – particles and chemical reactions visualisation, genetics structures visualisationMeteorology – visualisation of complex weather processes as well as disasters (e.g. tornados, earthquakes)Astronomy and radioastronomy – presentations of sky maps, stars and planets

CONCLUSION
•More over two of the four image sensors are used for sensing green signals and one for red and blue signals, this feature enables to improve the luminance signal resolution and to chromatic aberration to obtain extremely high resolution images.•These technologies for very high resolution imaging can be used for making various shv content such as live sporting,digital cinemas and medical application.
