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.

• 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: 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

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.
