Title:
COLOR CHART
Document Type and Number:
WIPO Patent Application WO/2021/256458
Kind Code:
A1
Abstract:
In the prior art, when the relationship between the color of a color chip (patch) in a color chart and the color of a color chip in an imaged color chart is computed, extraction of the color chip of the imaged color chart has been performed manually by operating a keyboard and a mouse. Such work has presented a problem in that, if there is a possibility that an error has occurred in extraction, manually extracting all color chips in the color chart takes time. The present invention addresses this problem by means of a color chart having a plurality of patches and an automatic recognition marker for automatically recognizing at least one of the plurality of patches, the color chart making it possible to easily carry out automatic recognition.
