ABSTRACT
The main concerns in the design of digital still cameras (DSCs) are cost, size, image quality, and operational/power efficiency [1]. To reduce cost and size, most DSCs capture images using an electronic sensor overlaid with a color filter array (CFA), sampling one of three color primaries at each pixel location. The two missing color components are then estimated to restore full-color information [2], [3], [4], [5], [6]. The process is referred to as demosaicking [7], [8], [9], [10], [11]. For additional information on the fundamentals on single-sensor color imaging refer to Chapter 1.
