    摘要: In a colorimetric apparatus including a support base configured to support a colorimetric object, a carriage including a detection unit configured to detect a detection target portion formed at the colorimetric object, the carriage supporting a colorimeter, and a movement unit configured to move the carriage, an adjustment value is calculated based on a detection position of the detection unit where the detection unit is caused to detect a detection target portion and a color measurement position of the colorimeter where the colorimeter is caused to measure a color of the detection target portion, and a position of the carriage at the time when a color of a patch is measured is adjusted based on the adjustment value.

    摘要: When relation between a color of a color chip (a patch) in a color chart and a color of a color chip in an image-captured color chart is calculated, the color chip of the image-captured color chart was manually extracted by operating a keyboard or a mouse. Such an operation had a problem that an extraction error may occur, and that it takes time to manually extract all color chips in the color chart. The present invention solved the problem by a color chart in which recognition can be easily and automatically executed. The color chart includes a plurality of patches, and an automatic recognition marker configured to automatically recognize at least one of the plurality of patches.
