Camera Module (OV7670) โมดูลกล้องสำหรับ Arduino

OV7670 image sensor, small volume, low work voltage, providing a single piece of VGA camera and image processor all functions. Can be output by SCCB bus control, the whole frame, sampling, take the way such as window of various resolution 8 bits of data. The product VGA image to a maximum of 30 frames per second. Users can complete control of image quality, data format and transmission mode. All the process of image processing functions, including gamma curve, white balance, saturation and chroma can be through the SCCB programming interface. OmmiVision image sensor application of sensor technology, unique to reduce or eliminate the optical or electronic defect such as fixed pattern noise, tail, float away, etc., improve the quality of the image, get clear and stable color images.
