Abstract
A projection image adjustment method includes acquiring a captured image produced by capturing an image of a range containing a first and second region in a situation wherein a first projector projects a first image having uniform luminance toward a first region and a second projector projects a second image having uniform luminance toward a second region overlapping part of the first region, identifying based on the captured image the brightness at a third region where the first region and the second region overlap each other, and the brightness at a fourth region that is part of the first region and does not overlap with the second region, adjusting the first image when the fourth region is darker than the third region, and not performing correction that adjusts the first image to increase the highest brightness at the fourth region when the fourth region is brighter than the third region.
