Abstract :
A multimedia-use color camera has been developed which provides not only an analog video output but also digital images of various formats such as a CIF (common intermediate format) YC video image and an RGB (red, green, blue) still image with square pixels. In order to generate many image formats flexibly, the following technologies have been developed: (1) programmable CCD (charge coupled device) scanning, (2) programmable interpolation, and (3) programmable color matrix
