Sony improves back-illuminated CMOS sensor

Sony developed next-generation “stacked” back-illuminated CMOS image sensors with RGBW coding and HDR movie functions to “realizes higher image quality and superior functionality in a more compact size.”

Sony says its RGBW coding function “allows images to be captured with low noise and high picture quality even in low-light conditions,” thanks to a white pixel added to the conventional RGB array; its HDR function “allows brilliant color to be captured even in bright settings.”

The three new sensor models, with resolutions from 8 to 13 megapixels, will begin sampling in March 2012.
