Abstract: A digital camera 1 comprises a degree-of-color similarity determiner 104, a gain setter 105 and a gradation corrector 106. Degree-of-color similarity determiner 104 determines, based on color information on all pixels of each of a plurality of block areas of an image whose gradation is to be corrected, a degree of similarity of the hue of that block area to a specified reference color. Correction factor setter 105 sets, for each pixel, a correction factor corresponding to the degree of similarity of a hue of the block area determined by the determiner. Gradation corrector 106 corrects the brightness of that pixel based on the correction factor set for that pixel by the setter.
