Abstract:
1. A projector comprising: a projection unit which projects a projection image of a projection target image on a projection surface; a projection control unit which causes the projection unit to project a second image when a first image is projected on the projection surface by an other projector, the first image including a first pattern which represents positions of a plurality of measurement patterns, the second image including a second pattern which represents positions of a plurality of measurement points and is different from the first pattern; an imaging unit which images the projection surface and creates a captured image; an image analysis unit which detects the first and second patterns from the captured image which is acquired from the imaging unit; and a correction processing unit which corrects the projection target image such that the projection image projected by the projection unit and the projection image projected by the other projector are in a desired relationship based on a detection result of the image analysis unit.
