Abstract:
A color measurement device acquires an image of a relative position calibration chart. The relative position calibration chart includes a calibration figure having a given calibration feature that has a position that is detectable along at least one of a first and a second direction. A color measurement of the relative position calibration chart is performed. Relative position relationship-related information is derived based on the calibration feature in the image of the relative position calibration chart and the calibration feature in the color measurement of the relative position calibration chart. A color of each patch of a number of patches of a color chart is measured at a position corresponding to one of the patches while correcting the position of the patch based on the position relationship-related information.
