C3188A - 1/3" Digital Output Colour Camera Module (OV7620)

The C3188A is a 1/3" colour camera module with digital output that uses the Omnivision OV7620 highly integrated CMOS digital colour video camera chip.

The digital video port supplies a continuous 8/16 bit-wide image data stream. All camera functions, such as exposure, gamma, gain, white balance, colour matrix, windowing, are programmable through I²C interface. If combined with the OV511+ USB controller chip available from OVT it can easily form a USB camera for PC applications.

Camera is supplied as standard with an f6.0mm F1.6 lens on a 12mm screw mount allowing focal point adjustment.
