Compact camera sensor suits laptop use

OmniVision Technologies' OV7725 VGA CameraChip sensor delivers the light sensitivity required for the low light conditions in which most consumers use their notebook computers.

OmniVision Technologies has released its high-sensitivity OV7725 VGA CameraChip sensor for embedded notebook cameras.

The quarter-inch OV7725 is built with a 6 x 6 micron pixel to deliver the light sensitivity required for the low light conditions in which most consumers use their notebook computers.

"OmniVision has gained good traction in the notebook PC market with design wins with eight of the top 10 notebook makers", said Bruce Weyer, Vice President of Marketing at OmniVision.

"We listened to our customers and found that there was strong demand for higher quality VGA sensors to improve the performance of the video conferencing capabilities of embedded notebook cameras".

"With the OV7725, our engineers have been able to deliver our highest quality VGA sensor to date".

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.

The high chief ray angle allows for a reduction in module height, a critical element in building cameras that can fit in today's thin notebook computers.

The OV7725 can operate at 60 frames per second in VGA mode, or 120 frames a second in QVGA for optimal performance in PC multimedia and gaming applications.

All required image processing functions, including exposure control, gamma, white balance, colour 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, clean and stable colour image.

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