Projection image adjustment method, information processing apparatus, and non-transitory computer-readable storage medium storing program

Abstract

A projection image adjustment method includes acquiring first captured image by capturing image of first image projected at first position on projection surface and second image projected at second position on projection surface and at least partially overlapping with first image, acquiring first amount of shift between first image and second image based on first captured image, moving first image from first position to third position separate therefrom in first direction, acquiring second captured image by capturing image of first image projected at third position and second image projected at second position, acquiring second amount of shift between first image and second image based on second captured image, and moving second image from second position to a fourth position separate therefrom in a second direction that is the opposite direction of the first direction when the second amount of shift is smaller than the first amount of shift.
