Abstract

Recently, color filter array patterns based on optimal design by reducing interchannel aliasing have been developed. Although these optimally subsampled patterns produce less degradation of resolution for the images in daylight about 6500 K, aliasing and grid effect become more prominent under the different lighting conditions. Moreover, the color interpolation (CI) for Bayer pattern cannot be utilized for these patterns. Since it is impossible to change coated patterns according to various conditions, CI algorithms have to compensate for light variations. In this letter, a method for generating intermediate quincuncial pattern is proposed for two patterns. Also, edge adaptive interpolation for the quincuncial pattern is carried out. Experimental results show that the proposed method reduces aliasing and grid effect.
