Abstract
A projector includes: an image projection unit which projects an image corresponding to image information; an image pickup unit which shoots the image projected from the image projection unit; an image switching unit which switches state of the image based on a predetermined phenomenon; and a projection condition control unit which allows the image projection unit to project a predetermined test image at the time when the image switching unit switches state of the image, and allows the image pickup unit to shoot the projected test image to control projection condition of the image based on the picked-up image result.
Claims13
A projector comprising:
- a plurality of image information input terminals to which image information is inputted, each of the plurality of information input terminals being configured to receive image information from a separate external device;
- an image projection unit which projects an image corresponding to image information received by a selected one of the plurality of image information input terminals;
- an image pickup unit which shoots the image projected from the image projection unit;
- an operation input unit which receives operation input;
- an image switching unit which switches the image projected from the image projection unit by switching which one of the plural image information input terminals is selected based on the operation input received by the operation input unit;
- and
- a projection condition control unit which allows the image projection unit to project a predetermined test image at the time when the image switching unit switches which one of the plural image information input terminals is selected, and allows the image pickup unit to shoot the projected test image to control projection condition of the image based on the picked-up image result.
A control method of a projector which has an image pickup unit and a plurality of image information input terminals to which image information is inputted, each of the plurality of information input terminals being configured to receive image information from a separate external device, the control method comprising:
- projecting an image corresponding to image information received by a selected one of the plurality of image information input terminals;
- shooting the projected image;
- receiving operation input;
- switching the image projected from the image projection unit by switching which one of the plural image information input terminals is selected based on the received operation input;
- and
- allowing a predetermined test image to be projected at the time of switching which one of the plural image information input terminals is selected, and allowing the projected test image to be shot to control projection condition of the image based on the picked-up image result.
