CAM-C3188A
Sept. 2004
1/3 ” Color Camera Module with Digital Output
The CAM-C3188A is a 1/3” color camera module with digital
output. It uses OmniVision ’s CMOS image sensor Ov7620.
Combining CMOS technology together with an easy to use
digital interface makes CAM-C3188A a low cost solution for
higher quality video image application. The digital video port
supplies a continuous 8/16 bit-wide image data stream. All
camera functions,such as exposure, gamma,gain,white
balance,color matrix,windowing,are programmable through
