OV7725 VGA product brief high performance, all-digital VGA camera solution available in a lead-free package The OV7725 CameraChip™ sensor is a highperformance 1/4 inch, single-chip VGA camera and image processor in a small footprint package. Operating at full functionality, the OV7725 meets all pc multimedia and cameraphone market requirements in terms of performance, quality and reliability. The lowpower OV7725 excels in low light conditions and can operate in a wide temperature range, from -20ºC to +70ºC. The OV7725 incorporates a 640 x 480 image array, capable of operating at 60 frames per second in VGA mode with complete user control over image quality, formatting and output data transfer. The OV7725 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 OV7725 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.
