  • Image correction device, image correction method, and image correction program
    Patent number: 10346711
    Abstract: A color gamma processing unit subjects an input image to gamma correction for color on a pixel by pixel basis. A GSDF processing unit subjects the input image to gamma correction for monochrome on a pixel by pixel basis. A mixer mixes a gamma corrected value for color provided by the color gamma processing unit with a gamma corrected value for monochrome provided by the GSDF processing unit at a mixing ratio based on a pixel-by-pixel saturation value of the input image, and outputs a gamma corrected value of a pixel in the input image.
    Type: Grant
