20110317936 | Image Processing Method and Computer Program - To obtain an output image where contrast relating to the luminance of an input image has been adjusted. In an image processing method for adjusting the luminance value of each pixel contained in an input image, first, a closed region β(x, y) made up of a plurality of pixels in the input image is demarcated as a target region, and the target region is moved within the input image by predetermined pixel units. At this point, a maximum value and a minimum value of luminance energy defined as a luminance arrangement in the target region are calculated, and difference data of the luminance energy is calculated (step S | 12-29-2011 |
