Abstract
An image processing apparatus comprises a specification unit configured to, from a multi-screen display corresponding to multi-screen displays performed by a plurality of projection apparatuses, specify an overlapping region in which first and second projection regions for first and second projection apparatuses overlap; a determination unit configured to, based on the positions of the overlapping regions in the first and second projection regions, determine luminance correction coefficients corresponding to the overlapping region such that the luminance correction coefficient at a coordinate corresponding to a first vertex in the overlapping region and a luminance correction coefficient at a coordinate corresponding to a second vertex located diagonally opposite to the first vertex in the overlapping region are different; and a correction unit configured to correct luminance of image data for the multi-screen display, based on the determined correction coefficients.
