PROBLEM TO BE SOLVED: To provide a technique capable of highly accurately performing the colorimetry of the narrow range of a test pattern.SOLUTION: A colorimetric device includes an imaging part (area sensor U1) for imaging a test pattern TP and acquiring the imaging information DT1 of the test pattern TP, a reference colorimetric part (colorimetric sensor U2) for performing the colorimetry of the test pattern TP and acquiring the reference colorimetric value DT2 of the test pattern TP, and a calibration part U4 for acquiring the colorimetric result DT3 of the test pattern TP in a range (raster RA) narrower than a colorimetric range R2 for acquiring the reference colorimetric value DT2 by the reference colorimetric part (U2), in at least one direction on the basis of at least the imaging information DT1 and the reference colorimetric value DT2.SELECTED DRAWING: Figure 1 |
