C3188A 1/3” Color Camera Module With Digital Output General Description The 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 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 I2C interface. In combine with OV511+, USB controller chip, it will be easily form a USB camera for PC application.
