Paper Abstract

Recent developments in spatio-spectral sampling theory for color imaging devices show that the choice of color filter array largely determines the spatial resolution of color images achievable by subsequent processing schemes such as demosaicking and image denoising. This paper highlights the cost-effectiveness of a new breed of color filter array patterns based on this sampling theory by detailing an implementation of the demosaicking method consisting of entirely linear elements and comprising a total of only ten add operations per full-pixel reconstruction. With color fidelity that rivals the state-of-the-art interpolation methods and an order of complexity near to that of the bilinear interpolation, this joint sensor-demosaicking solution to digital camera architectures can fulfill the image quality and complexity needs of future digital multimedia simultaneously.
