Abstract

This is an update from our ongoing studies on a biologically inspired, digital color image representation presented here before. It has evolved into a technology named Chromaplex^TM, with practical applications for both static (still pictures) and dynamic (digital video and motion pictures) images in three areas: (1) Simplification of processing, storage, compression, and transmission of digital color images. (2) Economical full-color upgrading of black and white (gray scale) image capturing systems. (3) Increase up to 4X of spatial resolution in high-quality digital image capturing systems currently designed for triplane color capture (three separate CCDs or three scans). Sample images of these applications are available on a world wide web site. In this paper we present data showing that spatial blur artifacts are worse when produced by conventional techniques of color interpolation than those produced by Chromaplex decoding. We also show that Chromaplex color decoding of CCD outputs, first demonstrated for CCDs with relatively narrow-band RGB filters, is equally applicable to digital imaging systems having CCDs with broad band subtractive color filters (like cyan, yellow, and magenta), but the often necessary color transformation from subtractive color to RGB brings in different tradeoffs.
