Description
The CS7654 is a low-power Digital Color-Space Proces-
sor for CCD cameras. It provides all the necessary digital
image processing for standard four-color interline trans-
fer CCD imagers. The CS7654 processes the magenta,
yellow, cyan, and green (MYCG) CCD imager data into
YCrCb formatted component digital video and into ana-
log PAL or NTSC. Internal processing includes color
separation, automatic white balance, user programma-
ble
gamma
correction,
(interpolation), digital output formatting and encoding
function for analog output. Also, a special "Chroma Kill"
circuit eliminates false colors during saturation. Video
output can be formatted to be compatible with NTSC-M,
NTSC-J, PAL-B,D,G,H,I,M,N, and Combination N sys-
tems. Closed Caption is supported in NTSC. Three 10-
bit DACs provide two channels for an S-Video output
port and one composite video outputs.A High-speed I

compatible control interface is provided for in system design.
A general purpose I/O port is also available to help con-
serve valuable board space and to provide up to eight
“boot” configurations.The CS7654 is designed to work
directly with the CS7615 CCD Imager Analog Processor.
