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.
