Summary:PROBLEM TO BE SOLVED: To provide a two-dimensional colorimeter for optionally calibrating a plurality of arbitrary colors on the same image plane and having high processing efficiency and satisfactory operability. SOLUTION: A two-dimensional image is acquired by imaging a measuring object by an imaging sensor 2. A comparator 52 (determination means) performs color determination on a pixel-by-pixel, based on whether a color is a calibrating object color, with respect to the two-dimensional image acquired by the imaging sensor 2. Based on the result of determination by the comparator 52, a multiplier 51b (arithmetic means) performs operation for causing prescribed calibration information, corresponding to the calibrating object color to be reflected in the two-dimensional image on a pixel-by-pixel basis.
