Image Algorithmics Proposes to Extend DR in RGB-W Sensors

Seattle, WA-based Image Algorithmics comes with a way to extend DR of RGB-W sensors by eliminating the over-exposed W pixels in its demosaicing solution: "Our processing trades off overexposure performance with artifacting and can tolerate 6dB of overexposure on typical images with little artifacting. This corresponds to a 3dB increase in the dynamic range of the system and enables the RGBW CFA to equal the noise performance of a Bayer sensor with twice the pixel area."
