Abstract: A dentition image capturing system includes: illumination devices to radiate light; an imaging device to capture first and second dentition images in a predetermined exposure period; a high luminance region extraction unit to extract a high luminance region for the first and second dentition images; a high luminance region comparison unit to calculate a degree of similarity between the high luminance region of the first dentition image and the second dentition image; a halation region specification unit to specify the high luminance region of the first dentition image as a halation region in a case where the similarity degree is smaller than a predetermined threshold; an image synthesis processing unit executing image synthesis processing of extracting a trimming region in the second dentition image corresponding to the halation region and replacing the halation region with the trimming region; and a dentition image output unit to output the first dentition image.
