OV7670 image sensor which is small size and low operating voltage, providing single-chip VGA camera and image processor for all functions. Controlled by SCCB bus, 8-bit image data of various resolutions can be output by whole frame, sub-sampling, window fetching, etc. Products VGA images up to 30 frames / sec. Users can fully control the image quality, data formats and transmission. All image processing functions including gamma curve process, white balance, saturation, hue and so on through the SCCB interface programming.
