Abstract
A projection control apparatus is configured to control a first image projection apparatus that projects a first image and a second image projection apparatus that projects a second image so that the first image and the second image are superimposed on each other in a predetermined area. The projection control apparatus includes a corrector configured to correct an imaging characteristic for converting a received light amount into captured image data in an imaging apparatus configured to capture the first and second images, by using a pixel value of the predetermined area in the captured image data obtained from the imaging apparatus, and a controller configured to control at least one of the first and second image projection apparatuses using a corrected imaging characteristic.
