Keywords:OmniVision? VGA sensor OV7725? sensitivity high?

OmniVision Technologies Inc. introduces the high sensitivity OV7725 VGA CameraChip sensor for embedded notebook cameras. The 1/4-inch OV7725 is built with a 6 x 6 micron pixel to deliver the ultra-high-light sensitivity required for low-light conditions.

The OV7725 is a highly integrated CMOS CameraChip sensor that provides the full functionality of a VGA camera and image processor on a single chip. A unique feature of the OV7725 is its high chief ray angle, which allows for a reduction in module height, a critical element in building cameras that can fit in today's thin notebook computers, said OmniVision. The OV7725 operates at 60 frames per second (fps) in VGA mode, or 120fps in QVGA for optimal performance in PC multimedia and gaming applications.

All required image-processing functions including exposure control, gamma, white balance, color saturation and hue control can be programmed through the OV7725's serial camera control bus (SCCB) interface. The OV7725 uses proprietary sensor technology to improve image quality by reducing or eliminating common lighting and electrical sources of image contamination such as fixed pattern noise, smearing and blooming to produce a crisp and fully stable color image.

The OV7725 comes in a lead-free, 28pin CSP2 package.
