1. A projector controlling method comprising:
projecting, by a first projector, a first image onto a first region of a projection surface;
projecting, by a second projector, a second image onto a second region of the projection surface;
accepting an instruction of movement of a region where the first image is projected from the first region to a third region and movement of a region where the second image is projected from the second region to a fourth region;
upon reception of the instruction, moving the first image from the first region to the third region at a first movement speed by controlling the first projector, and moving the second image from the second region to the fourth region at a second movement speed by controlling the second projector;
setting the first movement speed based on a distance from the first region to the third region;
setting the second movement speed based on a distance from the second region to the fourth region;
setting the first movement speed at a speed greater than the second movement speed when the distance from the first region to the third region is longer than the distance from the second region to the fourth region; and
setting the first movement speed at a speed smaller than the second movement speed when the distance from the first region to the third region is shorter than the distance from the second region to the fourth region,
wherein the first image projected onto the third region and the second image projected onto the fourth region form a single image.
