Description

The CS7666 is a low-power Digital Color-Space Processor for CCD cameras. It provides all necessary digital image processing for standard four-color interline transfer CCD imagers. The CS7666 processes the magenta, yellow, cyan, and green (MYCG) CCD imager data into YCrCb formatted component digital video. Internal processing includes color separation, automatic white balance, user programmable gamma correction, programmable scaling (interpolation), and output formatting. Also, a special "Color Killer" circuit eliminates false colors during saturation.

The digital output of the CS7666 can be configured to comply with the ITU-601, ITU-656 and SMPTE-125/M standards. Additionally, HREF and VREF (or HSYNC and VSYNC) output pins are provided to support older analog video encoders and the current ZV-Port definition. The CS7666 is designed to work directly with the CS7615 CCD Imager Analog Processor, and is a drop in replacement for the CS7665.
