Abstract

As pixel sizes approach the diffraction limit, optical and carrier crosstalk will increase substantially. Very high crosstalk leads to a reduction in SNR and color reproduction quality when conventional color filter arrays (CFAs) such as the Bayer patterns (RGB and CMY) are used. We present the design and analysis of new color filter array patterns for improving the color error and SNR deterioration caused by crosstalk in these sub-diffraction-limit (SDL) pixels.
