Sony’s Stacked, RGBW CMOS Image Sensor for Smartphones

DL Cade, PetPixel: The Sony LT29i codenamed Hayabusa will sport a 13 megapixel CMOS image sensor with stacked RGBW pixels and HDR movie capture. By stacking pixels you get larger pixels without making the sensor bigger—a good thing when space is a premium. RGBW adds a white pixel for better low light performance, but getting accurate colors might be tricky.
