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

摘要

An image correction device stores a plurality of correction curves for determining the amount of correction in a correction curve DB, calculates the feature value of the average luminance of an input image from the pixel value of each pixel in the input image, judges whether or not the calculated feature value is not less than a first threshold and, with respect to the input image judged to be the luminous image whose feature value is not less than the first threshold, counts the number of pixels which are not more than a second threshold in the input image. The image correction device then calculates the feature value of the average luminance from the pixel values of the counted pixels and acquires a correction curve from the correction curve DB on the basis of whether or not the calculated feature value is not less than a third threshold or whether the number of pixels which are not less than the third threshold out of the total number of the counted pixels is not less than a fourth threshold to correct the input image by using the acquired correction curve.
