IMAGE CORRECTION DEVICE, IMAGE CORRECTION PROGRAM, AND IMAGE CORRECTION METHOD

摘要

An image correction device calculates a feature value indicating the average brightness of an input image from the pixel value of each pixel in the input image and determines a pixel value which is the boundary to correct the pixels of the input image to be brighter or darker on the basis of the calculated feature value of the input image. The image correction device then calculates the area in which the amount of contrast correction is determined so that a pixel value smaller than the determined pixel value which is the boundary is darker and the area in which the amount of the contrast correction is determined so that a pixel value larger than the determined pixel value which is the boundary is brighter in the pixel values of the pixels in the input image and corrects the contrast of the input image on the basis of the calculated areas.
