Abstract: A method for sharpening of an image. The method combines edge sharpening and noise reduction on image and video data to eliminated artifacts, thereby creating natural looking output images and video without increased noise. The algorithm uses one dimensional look-up tables not requiring complex spatial frequency processing of input image and video data. The look-up tables reduce differences for small input differences which are likely noise, increase differences for mid-level input differences to increase edge slope and sharpness, and maintain high-level input differences to maintain sharp edges without noise increase on those edges that are already sharp. A device for sharpening an image is also disclosed, comprising of a processor in communication with a non-transitory computer readable medium storing the sharpening algorithm communicable to and executable by the processor.

Abstract: Methods of producing an output image with enhanced contrast are disclosed. A first set of methods is adaptive and region-based and comprises dividing a digital input image comprised of input image luma pixels into a plurality of blocks, and for each of the blocks, applying certain statistical analyses and computations to produce output image pixel data, communicating the output image pixel data to an image display device, and displaying the output image. A second set of methods is adaptive and uses human vision basis functions. A device for producing an output image with enhanced contrast is also disclosed.
