Samsung Announces High-definition CMOS Imagers for Webcams


Samsung Electronics has expanded its portfolio of CMOS image sensors to include two new CMOS image sensors - the S5K6A1 and the S5K5B3 - for use in notebook computers and other devices requiring video capture.

Samsung's new 1.3Megapixel (S5K6A1) and 2.1Megapixel (S5K5B3) imagers were developed with a strong emphasis on high-performance, real-time high-definition (HD) images at up to 30 frames per second (fps) at full resolution for internet video/image sharing and high quality VGA resolution for applications requiring video conferencing.

Low-light sensitivity during real-time video capture has also challenged image sensor designers. Using Samsung's enhanced 1.75um pixel technology, new imagers have significantly improved sensitivity and reaches 70Lux of YSNR10. This is critical when the only illumination on the scene might be from the computer screen itself.

As LCD panel makers develop ever thinner panels, the space requirements for embedded camera imagers in notebook computers is shrinking dramatically. Samsung's new S5K5B3 image sensor supports camera modules with full 1080p HD at 30fps capability in a z-height less than 4.5mm. Samsung's new S5K6A1 image sensor has been designed for camera modules with 720p HD at 30fps capability in a z-height less than 3.5mm.

Samsung new S5K5B3 and S5K6A1 imager sensors support multiple platforms architectures and controllers with both parallel and MIPI interfaces. Using an embedded solid state auto focus enhanced depth of field (EDoF) function, the S5K5B3 imager is also designed to allow bar codes and business card reading without needing mechanical autofocus support, which is more costly and a larger module form factor.

Samples for both of these CMOS image sensors are currently available with mass production scheduled for the second quarter 2010, Samsung said.
