Description :
OV7670 image sensor , small size, low voltage, providing single-chip VGA camera and image processor for all functions. By SCCB bus control , you can output the entire frame , sub-sampled , taking a variety of windows , etc. Resolution 8 affect the data . The product is VGA images up to 30 frames / sec. Users can fully control the image quality, data format and transmission. All image processing functions , including the process of gamma curves, white balance, saturation, color and so on through the SCCB interface programming.
