Panasonic has developed technology for highly sensitive image sensors that effectively doubles the brightness of color photography. It uses micro color splitters instead of conventional color filters in the image sensor.
Conventional image sensors produce color pictures by using red, green and blue filters for each pixel. The filters unfortunately account for a 50-70% light lost. Since Panasonic’s new technology does not use color filters, there is no light loss, resulting in an approximately double of the sensitivity. The technology can be produced using current semiconductor fabrication processes and can be applied to a CCD, CMOS, or BSI sensor.
