Patent number: 12078543Abstract: 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.Type: GrantFiled: June 15, 2021Date of Patent: September 3, 2024Assignee: DIC CorporationInventors: Masato Takahashi, Yasuhiro Morihara, Norimichi Tsumura, Ryo Takahashi, Keiko Ogawa, Isseki Kin
