摘要
The apparatus calculates a first relation representing a relation of mapping from an image capturing coordinate system of a camera to a shading correction coordinate system of a display apparatus, by using a first captured image acquired by capturing a first display image, and calculates a second relation by removing, from the first relation, a part corresponding to an object located between the first display image and the camera. The apparatus calculates a first gradation value in the shading correction coordinate system by performing a mapping transformation using the second relation on a second captured image acquired by capturing a second display image, calculates from the first gradation value a first correction value for the shading correction coordinate system, and calculates through an interpolation using the first correction value a second correction value for a part thereof where the first gradation value is not calculated.
