Abstract
An image processing method includes wavefront coding a wavefront that forms an optical image, converting the optical image to a data stream and processing the data stream with a color-specific filter kernel to reverse effects of wavefront coding and generate a final image. Another image processing method includes wavefront coding a wavefront that forms an optical image, converting the optical image to a data stream and colorspace converting the data stream. The method separates spatial information and color information of the colorspace converted data stream into one or more separate channels and deblurs one or both of the spatial information and the color information. The method recombines the channels to recombine deblurred spatial information with deblurred color information, and colorspace converts the recombined deblurred spatial and color information to generate an output image.
