OmniVision, a major manufacturer of mobile device imaging sensors (including the iPhone 4's), moves forward in the CMOS sensor pixel design race for smartphones with the 1/4-inch type OV8850 8-megapixel backside-illuminated sensor. (I bet you didn't even know there was a race.)
Without getting too technical, the sensor has a smaller footprint and uses a smaller 1.1-micron pixel, branded OmniBSI-2. The former allows for smaller devices while the latter improves power efficiency, but still provides similar image quality to the company's first-gen 1.4-micron OmniBSI pixel.
The OV8850 supports 8- and 10-bit raw image output … Read more
