Sony redesigns back-lit CMOS for improved smartphone cameras

Sony has developed CMOS designs to offer improved performance on small sensors and is planning three such sensors for smartphones and similar devices. The 'Stacked CMOS' design builds on the backlit CMOS idea by building the light-sensitive photo element on top of the processing circuitry, rather than combining them in a single layer. This creates a greater light-sensitive area while also making more space for processing circuitry. The company has also demonstrated two feaures that use the extra circuitry space of the design.
The first of these features is what Sony is calling RGBW Coding, which appears to be another attempt at including clear (white) pixels in the sensor's color filter arra... »read more
