描述 Description

The 1/6-inch OV9770 is an advanced CMOS image sensor designed for high performance 720p/30 fps high definition (HD) video applications for the notebook, tablet and entertainment markets. It is the first HD image sensor to use the new 1.75-micron OmniBSI™-2 pixel, delivering the best low-light performance (SNR10) and the highest sensitivity and dynamic range in its class. The new OmniBSI™-2 pixel architecture brings a 20 percent improvement in peak quantum efficiency, a 50 percent increase in full well capacity, and a 20 percent improvement in low-light performance, elevating the OV9770 to a new quality standard for HD video capture in 720p resolution.

A native 720p HD sensor, the OV9770 captures 30 frames per second (fps) in full 1280 x 720 resolution without losing image quality from degradation or image artifacts due to scaling or cropping. Image quality is further improved by minimizing lighting and electrical sources of contamination such as fixed pattern noise and smearing to produce a clean, stable color image. All required image processing functions including exposure control and defective pixel canceling are programmable through the Serial Camera Control Bus (SCCB) interface. The sensor also provides full-frame, sub-sampled or windowed 8-bit/10-bit images in RAW through the SCCB interface.

The OV9770 supports multiple platform architectures and controllers with both parallel and MIPI interfaces, significantly reducing product development time.
