  • Image enhancement using hardware-based deconvolution
    Patent number: 8154636
    Abstract: An image enhancement circuit (26, 60, 190, 260) includes an input interface (64, 262), which is operative to accept a stream of input pixel values belonging to pixels (32) of an input image. The input image includes a plurality of different input sub-images including respective subsets of the pixels, such that the input pixel values of the pixels in the different input sub-images are interleaved in the stream. A plurality of filter cells (92, 144, 206, 222, 238, 364) are connected in a two-dimensional array configuration and are arranged to separately filter the input pixel values of each of the input sub-images with respective two-dimensional deconvolution kernels so as produce respective output sub-images that include output pixel values. A multiplexer (88, 332) is coupled to multiplex together the output pixel values of the output sub-images so as to produce a filtered output image.
