  • METHOD AND APPARATUS FOR GENERATING ENHANCED IMAGES
    Publication number: 20110280494
    Abstract: A method and apparatus for generating an enhanced image is provided. The method includes receiving (101) an image to be enhanced. A set of sub images is generated (103) from the image where the different sub images correspond to different spatial frequency bands for the image. A pixel value variation is determined (107) in a neighborhood region of the first pixel region for at least a first pixel region of the image. An enhanced pixel region is then generated (109) for the enhanced image by combining the first pixel region and corresponding pixel regions of sub images in response to the pixel value variation. Specifically, a weighted summation of the input image and sub images may be generated with the weights being determined in response to the luminance variance in the neighborhood region. The invention may e.g. provide improved contrast enhancement with reduced artifacts and/or noise.

  • COLOR IMAGE ENHANCEMENT
    Publication number: 20110002540
    Abstract: A color image is enhanced in the following fashion. A saturation detector (SDT) detects a degree of color saturation (LC, CC) that occurs in an image area (SP). A filter arrangement (DE1, DE2, DE3) filters at least one spatial detail in the image area to a degree that depends on the degree of color saturation. This allows an improvement of perceptual quality of color images.
