  • determining first characteristic values, without storing pixel values of pixels, respectively of a plurality of regions of a first image by sequentially calculating, for each of the plurality of regions, characteristic values corresponding to each of the pixel values of the pixels included in each of the plurality of regions while sequentially receiving the pixel values of the pixels;

    obtaining, based on the determined first characteristic values, an illumination image related to a second image that is a following image of the first image; and

    modifying, based on the obtained illumination image, the second image,wherein the modifying comprises;

    determining whether at least a predetermined proportion of the pixel values of the pixels included in each of the plurality of regions of the first image are within a predetermined range; and
