C3038 1/4” Color Sensor Module With Digital Output General Description The C3038 is a 1/4” color sensor module with digital output. It uses OmniVision’s CMOS image sensor OV6630. Combining CMOS technology together with an easy to use digital interface makes C3038 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.
