Sony Officially Announces Exmor RS Sensor
Sony announces that it is working on a new type of backside-illuminated image technology that can reduce the sensor area while keeping the photodiode area at the same size. Alternatively, phone makers can retain the normal sensor size to improve noise characteristics and camera sensitivity. Given the greater push for an ever-slimmer smartphone, both approaches are of great importance for any phone manufacturer. It could be more sensible to take the middle ground, by reducing the sensor area somewhat, while still making the pixel size higher.
As of now, no official release date has been given for the technology and it could eventually be commercialized next year. An image sensor model codenamed ISX014 will be the first to arrive, offering 8Mp effective resolution. It can record 720p (1280×720) clips at 60 fps and full-HD (1920×1080) videos at 30 fps. Another image sensor model called IMX135 has a diagonal of 5.9mm and an effective resolution of 13Mp with similar video recording performance as the lower end model.
