Abstract:
To display an image even on a projection surface having complex unevenness similarly to a flat, a projection device includes: a storage unit storing at least a pattern image for detecting distortion depending on a state of the surface, an expected image associated with a displayed image of the pattern image displayed on a flat, and a desired projection image; a projection unit projecting an image including the pattern image and the desired projection image; an image acquisition unit acquiring a displayed image of the pattern image, and extracting a distortion image; a distortion amount calculating unit calculating a distortion parameter for distortion by comparing the expected image with the distortion image; a distortion correction processing unit correcting the projected desired projection image by using the distortion parameter; and an image output unit outputting, to the projection unit, image data including the corrected desired projection image and the pattern image.

Claim (Index 8):
The projection device according to  claim 1 , further comprising\n end pixel adjusting circuitry that adjusts a display area of an image to be displayed on the projection surface, when a peripheral portion of an image to be displayed on the projection surface is lacked, wherein the projector projects a pixel of an end portion of the expected image on the projection surface, the image acquisition circuitry acquires a position of a pixel of the end portion displayed on the projection surface, the end pixel adjusting circuitry generates a shrunk expected image obtained by shrinking the expected image in such a manner as to be present within an area of an end pixel reference position to be defined from a position of a pixel of the end portion acquired by the image acquisition circuitry, the image output circuitry outputs, to the projector, the pattern image shrunk in association with the shrunk expected image, the projector projects the shrunk pattern image output by the image output circuitry, on the projection surface, and the distortion amount calculating circuitry calculates the distortion parameter by comparing the distortion image corresponding to a displayed image of the shrunk pattern image with the shrunk expected image.
