OV7670 image sensor, providing single-chip VGA camera and image processor for all functions
n
nThrough the SCCB bus control, outputFull frame, sub-sampling, taking a variety of windows, etc. affect the data resolution
n
nProducts 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. OmmiVision image sensor applications unique sensor technology, by reducing or eliminating optical or electronic defects such as fixed pattern noise, prop tail, floating powder, etc., to improve image quality, get a clear and stable color image.
