COLOR ADJUSTMENT APPARATUS, COLOR ADJUSTMENT METHOD, AND PROGRAM

PROBLEM TO BE SOLVED: To display color matching accuracy in a visually intelligible manner.SOLUTION: A color adjustment apparatus (102) includes means for obtaining a first captured image by capturing a color chart (105) including patches (301C, 302C, 303C) with a reference camera (100), means (400) for obtaining a second captured image by capturing the color chart with a target camera (101), for obtaining information for color matching, and for generating a third captured image by applying the information to the second captured image, means (401) for outputting color difference signals of the first and third captured images, and means (402) for generating a first image based on color difference signals in areas corresponding to the patches among the color difference signals of the first captured image and a second image based on color difference signals in the areas among the color difference signals of the third captured image.
