Abstract

An image correction apparatus which improves the accuracy of color matching between image pickup apparatuses. The image correction apparatus performs color matching between the image pickup apparatuses using picked-up images generated by displaying a display image on a display screen and causing the plurality of image pickup apparatuses to shoot the display image. In the image correction apparatus, viewing angle correction values for use in correcting viewing angle characteristics resulting from positions of the plurality of image pickup apparatuses with respect to the display screen to a predetermined viewing angle characteristics are stored in memory, corrected images are generated by subjecting the display image in the picked-up images to correction using the viewing angle correction values, and color correction values for use in color matching between the plurality of corrected images are calculated.
