OmniVision promotes this device as the worlds first .25 inch, 2 mp camera chip. Citing zero-gap lenses and 2.2 um pixel size as the reasons the small size and an increased fill factor and well capacity for high sensitivity. Get inside the OmniVision 2Mp CMOS Image sensor to see how they continue to win sockets in small devices. This device enables camera modules that are thinner than most 1.3 megapixel camera modules and couples an embedded compression engine to allow camera manufacturers to use the same interface as the 1.3 Mp devices.
