SN9C102

Preliminary SN9C102 PC Camera Controller 1. General Description The SN9C102 is a single-chip backend processor to pair with the resolution of VGA or CIF CMOS image sensor. It reads the 9 or 8 bits input raw image data ( RGB Bayer pattern) from an image capturing device and outputs through a USB port into the PC. This chip includes three individual digital color gains setting (named R, G, B gains), an image compression engine, an offset compensation, a hardware windowing with random image size selection, panning and scaling functions. Its multi-powerful functions and special architecture make this chip suitable for extra low cost USB PC camera application. 2.
