 OV7670-FIFO Camera Module 

Introduction:

OV7670 image sensor, small volume, low operating voltage, providing all functions of a single chip of VGA camera and image processor. Through SCCB bus control, the sensor can output the whole frame, sampling, and various resolution 8 bits of data. The product VGA image can reach up to a maximum of 30 frames per second. Users can completely control the image quality, data format and transmission mode. All the process of image processing functions can be through the SCCB programming interface, including gamma curve, white balance, saturation and chroma . OmmiVision image sensor has been in application of unique sensor technology, by reducing or eliminating the optical or electronic defect such as fixed pattern noise, tail, floating away, etc., to improve the quality of the image, and get the clear and stable color images.
