OV26402 MPixel product brief
world’s smallest 2 megapixel CameraChip

package
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 significant improvements in the quantum
efficiency and full well capacity resulting in a very small but highly
sensitive 2.2 micron pixel.
The OV2640 is the world’s first 1/4 inch 2 megapixel
sensor. It’s a fully integrated CameraChip™ built on
OmniVision’s latest 2.2 micron OmniPixel2™
architecture and can be assembled in the very
popular 8 x 8 mm sockets with a building height as
low as 5 mm, essentially thinner than today’s 1.3
megapixel camera modules. This optimal sensor size,
coupled with an embedded compression engine,
allows customers to use the same camera interface
bandwidth as they have used with their 1.3 mega
pixel sensors, making it very easy to upgrade their
current platforms to the OV2640’s 2 megapixel
solution without hardware or mechanical changes.
In addition to the benefits of the OmniPixel2 architecture,
OmniVision also integrated an advanced image signal processing
block (OmniQSP™), which provides high-grade picture processing
and additional features traditionally only found in digital still
cameras. This advanced imaging processor has become very
important as the camera phone continues to evolve from a simple
gadget to a full fledged digital camera.
