"A color CMOS image sensor with the 4 x 4 White-RGB color filter array (CFA) including 50% white pixels has been developed. A transparent layer has been fabricated on the white pixel to realize over 95% transmission for visible light with wavelengths of 400-700 nm," scientists writing in the journal IEEE Transactions on Electron Devices report.
"Pixel pitch and number of the pixels were 3.3 mu m and 2 million, respectively. With the simple and low-noise color separation process, low-illumination signal-to-noise ratios of luminance signal have been increased by 6 dB, compared with those of the Bayer pattern. Moreover, by locating the pixels so that every color ...
