The camera is tested before leaving our factory. The purpose is to ensure the quality to prevent problems from causing various troubles to both parties. We only explains the related problems of the c8051 driver. If customer chooses the mcu by themself , we do not know the hardware situation and cannot explain it!

OV7670 image sensor, small size, low working voltage, provides all the functions of a single-chip VGA camera and image processor. Through SCCB bus control, it can output 8-bit impact data with various resolutions such as whole frame, sub-sampling, and windowing. The VGA image of this product reaches 30 frames per second. Users can fully control the image quality, data format and transmission method. All image processing functions including gamma curve, white balance, saturation, chroma, etc. can be programmed through the SCCB interface.
