Product Summary

The OV9655 is a quarter inch, low-voltage SXGA (1.3 MegaPixel) CMOS image sensor that offers the full functionality of a camera and image processor on a single chip, making it especially suitable for mobile applications. The OV9655 is built on OmniVision’s proprietary OmniPixel architecture which is a guarantee for excellent image quality because it reduces or eliminates common sources of image contamination such as fixed pattern noise and smearing to produce a clean, fully stable color image. OmniPixel’s unique pixel architecture also offers a high signal-to-noise ratio, enabling the OV9655 to perform exceptionally well in low-light conditions. The applications of the OV9655 are cellular and picture phones, PC multimedia, toys and digital still cameras.
