  • Patent number: 8111937
    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.

  • Patent number: 7995853
    Abstract: An image processing system includes a wavefront coding element that codes a wavefront forming an optical image, a detector for converting the optical image to a data stream and an image processor for processing the data stream with a reduced set filter kernel to reverse effects of wavefront coding and generate a final image. The reduced set filter kernel may include a reduced set distributive filter kernel. 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 reduced set filter kernel to reverse effects of wavefront coding and generate a final image. The processing consists of processing the image, for each pixel, with filter tap logic consisting of a shifter.

  • Patent number: 7379613
    Abstract: An image processing method includes the steps of wavefront coding a wavefront that forms an optical image, converting the optical image to a data stream, and processing the data stream with a filter kernel to reverse effects of wavefront coding and generate a final image. By example, the filter set kernel may be a reduced filter set kernel, or a color-specific kernel. Methods and systems are also disclosed for processing color images, such as by separating color and spatial information into separate channels. Methods and systems herein are for example useful in forming electronic devices with reduced opto-mechanical, opto-electronic and processing complexity or cost.
