Sony has made some specification changes to its upcoming Exmor RS stacked CMOS sensors, bound for the 2013 range of Xperia handsets. The main change is that it has removed the RGBW coding function from the sensors. This feature would have captured clearer images in low light due to the inclusion of a white pixel in addition to the RGB matrix.
Sony will instead revert to the RBG method instead as RGBW coding “was found not to meet certain conditions of Sony’s image quality standards.” This change affects the 13MP (IMX135; imaging module IU135F3-Z) and 8MP (IMX134; imaging module IU134F9-Z) CMOS sensors due to land in early 2013. The move is a shame as it was touted as one of the highlights of the new sensor, however it’s good that Sony has recognised the issue and doesn’t plan to ship a half-baked component.
