Claim One:
1. A color measurement device comprising: a color measuring sensor that measures a color; an imaging sensor that acquires images; an image acquisition processing circuit that causes the imaging sensor to obtain an image of a color chart, wherein the color chart comprises a plurality of patches, wherein each of the plurality of patches comprises a region of a given color; an edge information processing circuit that obtains edge information based on an edge of the image of the color chart; an edge statistic processing circuit that obtains edge statistic information of the edge by statistically processing the edge information; a patch position processing circuit that obtains position information of each of the plurality of patches based on the edge information and the edge statistic information; and a color measurement processing circuit that causes the color measuring sensor to measure the given color of each of the plurality of patches at a position of each of the plurality of patches of the color chart using the position information.
