OmniVisionImage Sensor from OmniVision for Mobile Cameras : OmniVision Technologies, the world's leading supplier of CMOS image sensors, today unveiled the world's first fully integrated 1/4 inch 2 megapixel CameraChip, the OmniVision OV2640. This new image sensor is based on OmniVision's latest 2.2 micron OmniPixel2 architecture, allowing it to be assembled in the very popular 8 x 8 mm sockets with a building height of about 6.5 mm. This is essentially the same size as today's standard 1.3 megapixel camera modules, giving mobile handset and device designers, for the first time, the ability to easily upgrade and implement a high volume mainstream 2 megapixel mobile camera solution.

The OV2640 takes advantage of the many process and design improvements of the new OmniPixel2 architecture, including more vibrant color, a zero-gap micro lens structure, an increased fill factor as well as new significant improvements in the quantum efficiency and "full well" capacity resulting in a very small but highly sensitive 2.2 micron pixel. "Most of our competitors are now just releasing their first 1/4 inch 1.3 megapixel sensors, something that we have provided for over 2 years," said Per Rosdahl, Senior Product Marketing Manager at OmniVision. "We are particularly proud to once again take the lead in camera miniaturization for the mid to high-end segment of the camera phone market."

OmniPixel2 architecture for Camphones
"We are experiencing very early success with the OV2640 with several design wins already secured," Rosdahl continued. "We believe the advantages of its size and features make it the clear choice for those customers wanting to take an early lead in the pixel race for mid to high-end camera phones." In addition to the benefits of the OmniPixel2 architecture, OmniVision also integrated an advanced image signal processor called OmniQSP. OmniQSP provides high-grade picture processing and features traditionally only found in digital still cameras (DSC). This advanced imaging processor has become very important as the camera phone continues to evolve from a simple gadget to a full fledged DSC.

OmniVision OV2640
The OV2640 is powered with an integrated compression engine, a major benefit to customers because it allows them to use the same camera interface bandwidth as the 1.3 megapixel sensor. Combined with the same form factor as a 1.3 megapixel sensor, customers adopting the OV2640 can easily upgrade their platforms to 2 megapixels without hardware or mechanical changes. The OV2640 is currently available for general sampling.
