OV7720 VGA product brief high-performance, all-digital security camera solution available in a lead-free package The OV7720 CameraChip™ sensor is a high-performance 1/4 inch, single-chip VGA camera and image processor that performs under low voltage conditions. Operating at full functionality in a small footprint package, the OV7720 meets all security and surveillance market requirements in terms of performance, quality and reliability. The OV7720 excels in low light conditions and can operate within a wide temperature range from -20°C to +70°C. It provides full-frame, sub-sampled or windowed 8-bit/ 10-bit images in a wide range of formats, controlled through the Serial Camera Control Bus (SCCB) interface. The OV7720 incorporates a 640 x 480 image array capable of operating at up to 60 frames per second (fps) in VGA with complete user control over image quality, formatting and output data transfer. The OV7720 possesses all required camera processing functions including exposure control, gamma, white balance, color saturation, hue control and more. These functions are also programmable through the SCCB interface.
