CORRECTION CONTROL DEVICE, CORRECTION METHOD, AND PROJECTOR

摘要

PROBLEM TO BE SOLVED: To provide a correction control device capable of acquiring, when a plurality of projectors project guides so that projection ranges thereof overlap with each other, information for accurately aligning projection positions of the projectors reliably from a photographed image; a correction method; and projectors.SOLUTION: A correction control device includes: a photographing control unit 151 that causes a photographing unit 143 to photograph guides 3A and 3B projected by projectors 2A and 2B on a screen SC; and an image analysis unit 152 that detects the guides 3A and 3B from an image photographed by the photographing unit 143. The photographing control unit 151, when the image analysis unit 152 cannot detect the guides 3A and 3B from the photographed image, changes settings related to photographing conditions and then causes the photographing unit 143 to perform photographing again.
