Abstract
An image projection apparatus includes a projection unit that projects a pattern image on a projection surface; an image capturing unit that captures the projected pattern image; and a corrector that corrects the captured image so that an imaging distortion caused due to image capturing and a projection distortion caused due to projection are corrected. The projection unit projects the corrected captured image at a predetermined position on the projection surface.
Claims8
An image projection apparatus comprising
- a projection unit that projects a pattern image on a projection surface;
- an image capturing unit that captures the projected pattern image;
- and
- a corrector that corrects the captured image so that an imaging distortion caused due to image capturing and a projection distortion caused due to projection are corrected, wherein
- the projection unit projects the corrected captured image at a predetermined position on the projection surface.
An image projection method comprising:
- projecting a pattern image on a projection surface;
- capturing the projected pattern image;
- correcting the captured image so that an imaging distortion caused due to image capturing and a projection distortion caused due to projection are corrected;
- and
- projecting the corrected captured image at a predetermined position on the projection surface.
A non-transitory computer-readable storage medium with an executable program stored thereon, wherein the program instructs a computer to execute:
- projecting a pattern image on a projection surface;
- capturing the projected pattern image;
- correcting the captured image so that an imaging distortion caused due to image capturing and a projection distortion caused due to projection are corrected;
- and
- projecting the corrected captured image at a predetermined position on the projection surface.
