OmniVision Technologies Inc. has introduced the OV7740, its latest solution for notebook Web cams. Developed specifically to address the low-light sensitivity demands of the fast-growing notebook PC market, the low-power, small profile OV7740 delivers 6,800mV/lux-sec sensitivity to optimize performance and dramatically improve image quality. Featuring a 4.2?pixel based on OmniPixel3-HS technology, the OV7740 provides the functionality of a single-chip camera in a 1/5-inch optical format, ideal for helping today's leading-edge notebook PC manufacturers meet constrained space requirements.

"Web cams are most often used in home and office environments with poor lighting. Therefore, light- sensitivity performance is paramount," said Todd Koelling, senior director of notebook, automotive and security marketing at OmniVision. "Our latest OV7740 sensor delivers the best of both worldsa smaller profile form factor and nearly double the light sensitivity of our previous generation sensors."

The OV7740 is capable of operating at 60fps in VGA resolution and 120fps in QVGA resolution with complete user control over image quality, formatting and output data transfer. It supports a digital video parallel port, and provides full-frame, sub-sampled, windowed or scaled 8bit/10bit images in RAW RGB and YUV formats.

The OV7740 is expected to further strengthen the Omnivision's position in the fast-growing notebook PC market. In addition to notebooks, the ultra-low light sensitivity of the OV7740 offers an ideal solution for security, surveillance, automotive, and games and toy applications.

The OV7740 is immediately available for sampling with volume production slated within the Q1 09.
