<p>An object is to represent the difference of colors of a vital tooth and a tooth sample in a highly precise manner and to compare the colors in a relatively easy manner. The invention provides a dental colorimetry apparatus including a shade-guide-information storage unit configured to store acquired image data of a tooth sample and colorimetric information of each pixel acquired on the basis of the acquired image data; a pixel extracting unit configured to acquire reference colorimetric information used as a reference when carrying out a comparison with the vital tooth, to compare the reference colorimetric information and the colorimetric information for each pixel of the tooth sample, and to extract pixels whose comparison results satisfy a predetermined condition; an image-generating unit configured to create a sample comparison image in which a third pixel group including pixels extracted by the pixel extracting unit and a fourth pixel group including pixels that are not extracted are represented by different colors; and a display device configured to display the sample comparison image created by the image-generating unit.</p> |
