Color adjustment apparatus used for color matching between image capturing apparatuses, color adjustment method, and storage medium storing color adjustment program

A color adjustment method comprising:

• obtaining a first captured image by capturing a color chart for color matching including patches by a first image capturing apparatus serving as a reference;
• obtaining a second captured image by capturing the color chart with a second image capturing apparatus serving as a correction target;
• obtaining correction information for the color matching;
• generating a third captured image by applying the correction information to the second captured image;
• outputting color difference signals of the first captured image and color difference signals of the third captured image;
• and
• generating first and second images, the first image being generated based on the color difference signals of the first captured image and first positional information indicating areas corresponding to the patches in the color chart of the first captured image by extracting the area indicated by the first positional information from the first captured image, and the second image being generated based on the color difference signals of the third captured image and second positional information indicating areas corresponding to the patches in the color chart a of the second captured image by extracting the area indicated by the second positional information from the third captured image.

A non-transitory computer-readable storage medium storing a color adjustment program causing a computer to execute a color adjustment method comprising:

• obtaining a first captured image by capturing a color chart for color matching including patches by a first image capturing apparatus serving as a reference;
• obtaining a second captured image by capturing the color chart with a second image capturing apparatus serving as a correction target;
• obtaining correction information for the color matching;
• generating a third captured image by applying the correction information to the second captured image;
• outputting color difference signals of the first captured image and color difference signals of the third captured image;
• and
• generating first and second images, the first image being generated based on the color difference signals of the first captured image and first positional information indicating areas corresponding to the patches in the color chart of the first captured image by extracting the area indicated by the first positional information from the first captured image, and the second image being generated based on the color difference signals of the third captured image and second positional information indicating areas corresponding to the patches in the color chart a of the second captured image by extracting the area indicated by the second positional information from the third captured image.
