Image processing system, projector, program, information storage medium, and image processing method
First Claim
1. An image processing system, comprising:
- an adjustment section which generates edit image information for projecting an edit image including a content image based on input image information and a position change detection image at least partially provided outside the content image;
a sensing section which senses a projection target onto which the edit image is projected and generates sensing information indicating a sensed image;
a projection section which projects the content image based on the input image information and projects the edit image based on the edit image information; and
a determination section which determines whether or not a relative position between the projection section and the projection target has changed based on the sensing information, the determination section determining whether or not the relative position has changed by determining the presence or absence of the position change detection image in a projection target area corresponding to the projection target in the sensed image.

Abstract
A projector including: an adjustment section which generates edit image information for projecting an edit image including a content image based on input image information and a position change detection image at least partially provided outside the content image; a sensing section which senses a screen onto which the edit image is projected and generates sensing information indicating a sensed image; a projection section which projects the edit image based on the edit image information; and a determination section which determines whether or not a relative position between the projection section and the screen has changed based on the sensing information.

8. A program readable by a computer including a sensing section, a projection section, and a determination section, the program causing the computer to perform processing for:
-
the projection section to project an image including a position change detection image at least partially provided outside a content image based on input image information;
the sensing section to sense a projection target onto which the image is projected and to generate sensing information indicating a sensed image; and
the determination section to determine whether or not a relative position between the projection section and the projection target has changed based on the sensing information, the sensing section sensing the projection target in a sensing range including the projection target area; and
the determination section determining whether or not the relative position has changed by determining the presence or absence of the position change detection image in a projection target area corresponding to the projection target in the sensed image. - View Dependent Claims (9)

10. An image processing method conducted by a computer including a sensing section, a projection section, and a determination section, wherein:
-
the projection section projects an image including a position change detection image at least partially provided outside a content image based on input image information;
the sensing section senses a projection target onto which the image is projected and generates sensing information indicating a sensed image; and
the determination section determines whether or not a relative position between the projection section and the projection target has changed based on the sensing information, the sensing section senses the projection target in a sensing range including the projection target area; and
the determination section determines whether or not the relative position has changed by determining the presence or absence of the position change detection image in a projection target area corresponding to the projection target in the sensed image.
