Abstract
A conversion table is generated from an average luminance value, a histogram, and a peak luminance value of an input image, and is used for conversion of the input image to generate an output image, for display at an image display. The conversion table has a feature by which, when the input gradation value is equal to the peak luminance value, the gradation value of the output image is made to be also equal to the peak luminance value, and, in at least part of a range in which the input gradation value is lower than the peak luminance value, the output gradation value is made to be smaller than the gradation value of the input image.
