发明名称 Projector and control method for the projector
摘要 A projector includes a projecting unit configured to project an image on a projection surface, a projection control unit configured to cause the projecting unit to project a correction pattern including a first pattern and a second pattern, and a correction control unit configured to detect the first pattern and the second pattern included in the projected correction pattern and correct distortion of the projected image. The correction control unit detects the second pattern projected on a screen and detects the position of the first pattern on the basis of the position of the detected second pattern.

主权项 1. A projector comprising: a projecting unit configured to project an image on a projection surface; a control unit configured to cause the projecting unit to project an image for adjustment including a first pattern and a second pattern; a correcting unit configured to detect the first pattern and the second pattern included in the image for adjustment projected by the projecting unit and correct distortion of the projected image; and an image pickup unit configured to photograph the projection surface, wherein the correcting unit detects the first pattern from a photographed image of the image pickup unit and corrects the distortion of the projected image, wherein the correcting unit detects the second pattern projected on the projection surface and detects the position of the first pattern on the basis of the position of the detected second pattern, and the image for adjustment includes, as the second pattern, a figure having a predetermined shape arranged to be reflected on an epipolar line in a projecting direction of the image for adjustment or in a vicinity of the epipolar line on the photographed image of the image pickup unit.
