IMAGE PROJECTION APPARATUS AND METHOD FOR CONTROLLING THE SAME
First Claim
1. An image projection apparatus comprising:
- a measuring unit that measures a distance from the image projection apparatus to a projection surface;
a generating unit that generates a first operation image if the measured distance is less than a threshold value and generates a second operation image if the measured distance is not less than the threshold value, wherein the first operation image is an image with respect to which an operation can be input by pointing on the first operation image that is being projected with a body part of a user, and the second operation image is an image with respect to which an operation can be input by operating a cursor displayed in the second operation image that is being projected using a predetermined operating unit; and
a projecting unit that projects an operation image generated by the generating unit onto the projection surface.

Abstract
There is provided an image projection apparatus comprising: a measuring unit that measures a distance from the image projection apparatus to a projection surface; a generating unit that generates a first operation image if the measured distance is less than a threshold value and generates a second operation image if the measured distance is not less than the threshold value, wherein the first operation image is an image with respect to which an operation can be input by pointing on the first operation image that is being projected with a body part of a user, and the second operation image is an image with respect to which an operation can be input by operating a cursor displayed in the second operation image that is being projected using a predetermined operating unit; and a projecting unit that projects an operation image generated by the generating unit onto the projection surface.

6. A method for controlling an image projection apparatus, comprising:
-
a measuring step of measuring a distance from the image projection apparatus to a projection surface; a generating step of generating a first operation image if the measured distance is less than a threshold value and generating a second operation image if the measured distance is not less than the threshold value, wherein the first operation image is an image with respect to which an operation can be input by pointing on the first operation image that is being projected with a body part of a user, and the second operation image is an image with respect to which an operation can be input by operating a cursor displayed in the second operation image that is being projected using a predetermined operating unit; and a projecting step of projecting an operation image generated in the generating step onto the projection surface. - View Dependent Claims (7, 8, 9, 10)

11. An image projection apparatus that is capable of projecting an image and a GUI and that, if a GUI is being projected, allows the GUI to be operated using an operating unit that is capable of operating the GUI, the apparatus comprising:
-
a measuring unit that measures a distance from the image projection apparatus to a projection surface; and a control unit that, if the distance measured by the measuring unit is less than a threshold value, performs control so as to change the GUI so that the user can operate the GUI by touching the projection surface instead of operating using the operating unit and also to execute a recognition function for recognizing a touch operation by the user. - View Dependent Claims (12)
