Abstract
An improved method and apparatus is provided for sensing scene light and providing sampled image data in three colors in response thereto. The sampled image data is subsequently interpolated for the non-sampled colors and thereafter subtracted to provide two color difference signals. The two color difference signals, in turn, are each median filtered and subsequently reconstructed in conjunction with the originally sampled image data to provide an image of the subject with substantially reduced color fringing. The median filter preferably filters color difference signals corresponding to a select number of image sensing elements separated with respect to each other by non-select image sensing elements.
