HD Video Sensor
Feb 2010Omnivision Technologies Inc.Request Info
A high-definition (HD) video sensor has been unveiled by OmniVision Technologies Inc. The compact OV9726 delivers 720-pixel HD video at 30 fps and is suitable for use in notebooks, netbooks, webcams, mobile phones, portable media players and other mobile entertainment devices. Built on a proprietary 1.75-µm back-side illumination pixel architecture, it achieves low-light sensitivity of 1480 mV/lx-sec in a 1/6.5 form factor. Because the image sensor receives light through the back of the chip, there is no metal wiring to block the image light, and the entire back of the sensor can be photosensitive. The front of the chip surface area is devoted entirely to processing, increasing the number of metal layers. Capturing light on the back of the sensor reduces the distance that the light has to travel to the pixels and provides a wider angle of light acceptance.
