OV7670Image sensor, small size, low working voltage, single chipVGAAll functions of camera and image processor. bySCCBBus control, can output various resolutions such as whole frame, sub-sampling, window taking, etc.8Bit affects the data. this productVGAImage up to30frame/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 passedSCCBInterface programming.OmmiVisionThe image sensor uses 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, and floating.
