The OV7670 image sensor is small in size and low in operating voltage, and provides all the functions of a single-chip VGA camera and image processor. Through SCCB bus control, various resolution 8-bit impact data can be output in the form of full frame, sub-sampling, windowing, etc. The VGA image of this product reaches a maximum of 30 frames/second. Users have complete control over image quality, data format and transfer method. All image processing functions including gamma curve, white balance, saturation, color, etc. can be programmed through the SCCB interface. The OmmiVision image sensor applies unique sensor technology to improve image quality and obtain clear and stable color images by reducing or eliminating optical or electronic defects such as fixed pattern noise, tailing, floating, etc.
