Sony has announced that its upcoming image sensors for smartphones and mobile devices will feature a new RGBW Coding. Usually photo pixels are encoded with RGB (Red, Green and Blue) but this W component stands for White, and is apparently used to store extra information about luminance. Sony is then able to use the extra information to improve the brightness of low-light photos for example – and the company claims that it can do so without adding a lot noise to the image.On another topic, Sony's new sensors also come with an HDR Movie function.
