OmniVision 8 megapixel Imaging Sensor

OmniVision’s latest 8 megapixel imaging sensor will probably make its way into cell phones sometime in the near future, as this CMOS image sensor apparently solves the pixel size problem thanks to a workaround using backside illumination (BSI) technology. BSI maximizes photon collection by “circumventing obstructive metal and dielectric layers on the top-side of the sensor die”, resulting in improved light absorption, thinner overall camera modules, and increased sensitivity as well as F stops with reduced crosstalk. While BSI is not new technology, OmniVision seems to be the first out of the stables to make this technology available to the masses. Just how many megapixels does a phone camera need, anyways?
