Abstract
An image correction method performed by a projector, the method including projecting a second image onto a projection surface, the second image is acquired by reducing a first image containing a plurality of candidate points that are candidates for display position correction to a size that falls within a projection area that is the largest area over which the projector is capable of projection, accepting a first input to select a target point that is a display position correction target out of the plurality of candidate points in the state in which the second image is projected on the projection surface, projecting a third image onto the projection surface, the third image is acquired by enlarging the second image to the size of the first image after accepting the first input, accepting a second input to change the display position of the target point in the state in which the third image is projected on the projection surface, and projecting a projection image acquired by correcting the shape of an input image based on the second input onto the projection surface.
