Highly accurate color correction is conducted so that color information also matches on different side surfaces of the same tooth such as the buccal surface and the occlusal surface. Provided is a dental image processor (5) comprising: a memory (8) for storing position information of a reference region having a color correlation with standard color information, which is the color information acquired in another region of either the occlusal surface or the buccal surface, the reference region being a region on an image (G1) constituting a correction target acquired for either the occlusal surface or the buccal surface of the tooth; a reference color information extraction unit (9) for extracting the reference color information, which is the color information in the reference region of the image (G1); a correction coefficient calculation unit (10) for calculating the correction coefficients which match the reference color information extracted by the reference color information extraction unit (9) to the standard color information; and a color information correction unit (11) for correcting the color information of the image (G1) by using the correction coefficients calculated by the correction coefficient calculation unit (10).
