Nikkei: Sony presented its new RGB-IR solution at Infrared Array Sensor Forum 2015 on July 31, 2015. Sony has replaced a half of G color in Bayer CFA with white (W). By using data of the three primary colors in addition to W to perform data processing, it becomes possible to remove only near-infrared light signals, Sony said. As a result, a color image can be taken by without an IR-cut filter. The new technology is said to enable existing image sensors to take an image using not only visible light but near-infrared light just by replacing a color filter and image processing software. The color filter is supplied by Fujifilm.
