1. A projector controlling method comprising:
acquiring first imaging information obtained by capturing a first image projected from a projector at a first timing, wherein first characteristic information representing characteristics of the first image is generated based on the first imaging information, wherein the projector is fixed at an installation position via two or more installers;
acquiring second imaging information obtained by capturing a second image projected from the projector at a second timing, wherein second characteristic information representing characteristics of the second image is generated based on the second imaging information;
evaluating whether or not a change in a posture of the projector satisfies a certain criterion based on the first imaging information and the second imaging information, wherein the evaluation is further based on the first characteristic information and the second characteristic information; and
outputting information based on a result of the evaluating, the information including information on an installer out of the two or more installers that affects the change in the posture of the projector.
