Abstract
The present invention is a calibration apparatus comprising a calibration unit configured to perform calibration for an image display apparatus; an acquiring unit configured to acquire a color deviation direction that represents a direction of deviation in a color space between a color measurement value and a theoretical value, for each of color patches of a plurality of colors after executing the calibration; and a control unit configured to determine degrees of similarity of the color deviation directions in relation to the color patches of at least some of the plurality of colors included in the plurality of colors and control whether or not the calibration unit is allowed to perform the calibration for the image display apparatus again, on the basis of a result of the determination.
Claims25
A calibration apparatus comprising:
- a processor;
- and
- a memory coupled to the processor to store instructions that cause the processor to perform operations of at least one of a plurality of steps including:
- a calibration step of performing calibration for an image display apparatus;
- an acquiring step of acquiring a color deviation direction that represents a direction of deviation in a color space between a color measurement value and a theoretical value, for each of color patches of a plurality of colors after executing the calibration;
- and
- a control step of determining degrees of similarity of the color deviation directions in relation to the color patches of at least some of the plurality of colors and controlling whether or not to repeat the calibration step for the image display apparatus, on the basis of a result of the determination.
A method for controlling a calibration apparatus, comprising:
- a calibration step of performing calibration for an image display apparatus;
- an acquiring step of acquiring a color deviation direction which represents a direction of deviation in a color space between a color measurement value and a theoretical value, for each of color patches of a plurality of colors after executing the calibration;
- and
- a control step of determining degrees of similarity of the color deviation directions in relation to the color patches of at least some of the plurality of colors and controlling whether or not to repeat the calibration step for the image display apparatus is performed again in the calibration step, on the basis of a result of the determination.
