| Abstract: |
In digital image display devices, data are typically presented via a spatial subsampling procedure implemented as a color filter array, a physical construction whereby each light emitting element controls the intensity level of only a single color. In this paper, we examine the problem of color filter array design with respect to spatial resolution and human vision; in doing so we quantify the fundamental limitations of existing designs by explicitly considering the spectral wavelength representation induced by the choice of array pattern, and propose a framework for designing and analyzing alternative patterns that minimize aliasing. An empirical evaluations on standard color test image confirms our theoretical results, and indicates the potential of these patterns to significantly increase spatial resolution while at the same time improving color image fidelity. |
