1. An image processing apparatus, comprising:
one or more processors; and
one or more memories containing instructions that, when executed by the one or more processors, cause the one or more processors to function as:
a specification unit configured to, based on a parameter of an image capturing apparatus, specify a region captured by the image capturing apparatus in a display screen in which display panels are arrayed, and
a correction unit configured to calculate an angle formed by a vector from a pixel in the region to the image capturing apparatus and a normal vector of the display screen, obtain a correction amount corresponding to the angle as a correction amount of a luminance value of the pixel, and correct the correction amount by multiplying a correction coefficient for correcting an individual difference regarding a luminance of a display panel with the correction amount of the luminance value of the pixel.
