Paper Abstract

Dispersive filtering has been shown to be an effective means to prevent color aliasing in digital images from sensors supplied with a mosaic filter pattern. Sensors with mosaic color filters typically measure only a portion of the color information for each pixel. To record full color information requires the information from several laterally displaced pixels. Dispersive filtering introduces a similar lateral displacement in the optical image. When sensed with the corresponding laterally displaced pixels, a color registered data set is produced. Limitations of available optical materials, and color sensors restrict the exact registration to an approximation. This paper quantifies the residual errors of dispersively registered images for two current mosaic sensor types.
