OV7670 VGA Camera Module for Arduino

OV7670 is a low CMOS image sensor and a VGA camera with a low operating voltage that provides the full functionality of a single-chip VGA camera and image processor in a small package. Through an SCCB (Serial Camera Control Bus) control, It provides full-frame, sub-sampled, and windowed 8-bit images in a wide range of formats. This camera module has an image array that can reach up to a maximum of 30 frames per second in VGA with complete user control over image quality, formatting, and output data transfer. All the functions or processes of image processing like exposure control, white balance, gamma, color saturation, hue, chroma, etc can be controlled and programmed through SCCB control. 

OV7670 VGA Camera Module uses proprietary sensor technology to improve image quality by reducing lighting/electrical sources of image contamination, such as fixed pattern noise, smearing blooming, etc and capable to produce a clean and fully stable color image.
