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 I
2
C interface.
In combine with OV511+, USB controller chip, it will be easily form a USB camera for PC application.
