It’s a low rated rumor but according to new source of SAR website Sony A7S II successor will carry RGBW sensor. If we look at the test reports when we compare a RGB sensor with RGBW sensor, then we see increase in brightness in images by 32% in high-contrast situations and decrease color noise by 78% in low-light.
1. Huawei P8 uses the RGBW Sensor
Till now only Huawei P8 uses the RGBW Sensor developed by Sony. The P8 is world first smartphone to feature a Dual camera module on the rear side of the camera and each module of the camera have a 13MP RGBW sensor inside it.
As you can see the P8 sensor is listed at sensor product page here.
2. What is RGBW Sensor
The RGB sensor carries extra white pixel inside it and due to that we see increase in brightness in images by 32% decrease color noise by 78% in low-light compared to a traditional CMOS Sensor. The Sony High sensor RGBW actually inspired from Kodak as you can see the Kodak press release published at dpreview at 2007.
3. Sony working on a Fullframe RGBW Sensor
