Abstract

A display device includes a projection unit adapted to display an image on a screen, a position detection unit adapted to detect a pointed position of a pointing body in the screen, and a control section adapted to perform a function related to an operation corresponding to an operation area in a case in which the operation area is disposed outside a display area of the image in the screen, and the pointed position detected by the position detection section is located within the operation area.

Claims

1. A display device comprising:

a display adapted to display an image on a display surface;

a detector adapted to detect an operation position in the display surface; and

a controller adapted to perform a function related to an operation corresponding to an operation area in a case in which the operation area is disposed outside a display area of the image in the display surface, and the operation position detected by the detector is located within the operation area.

2. The display device according to claim 1, further comprising:

a display controller adapted to display image data supplied from a plurality of image supply sections including an external device respectively in a plurality of display areas disposed in the display surface using the display,

wherein a plurality of the operation areas is set so as to correspond to each of the display areas.

3. The display device according to claim 1, wherein

in a case in which a plurality of the operation areas is set, and the detector detects an operation straddling two or more of the operation areas, the function corresponding to the operation straddling the two or more of the operation areas is performed.

4. The display device according to claim 1, further comprising:

an imaging device adapted to shoot a range including the display area,

wherein the detector detects the operation position based on a shot image of the imaging device, and

the operation area is set within a shootable area of the imaging device.

5. The display device according to claim 1, further comprising:

a recognition device adapted to recognize a pattern displayed in the operation area; and

a setting device adapted to make function information, which corresponds to the pattern recognized by the recognition device, correspond to the operation area,

wherein the controller performs a function based on the function information corresponding to the operation area in a case in which the operation position is located within the operation area.

6. The display device according to claim 5, wherein

the recognition device includes

a pattern detector adapted to detect the pattern displayed in the operation area,

a function storage adapted to store the function information corresponding to the pattern, and

a function acquisition device adapted to obtain the function information, which corresponds to the pattern detected by the pattern detector, from the function storage.

7. The display device according to claim 6, wherein

in a case in which the operation position is located within the operation area where the pattern fails to be detected by the pattern detector, the controller avoids performing any function.

8. The display device according to claim 1, wherein

in a case in which an operation to the operation area is detected by the detector, the controller performs at least either one of

a switching function adapted to switch an image displayed in the display area to another image,

a freeze function adapted to stop an image displayed, a mute function adapted to stop displaying an image,

a zoom function adapted to magnify or contract an image displayed,

a function adapted to change a display position of an image displayed in the display area, and

a function adapted to switch between a mode of processing information representing the operation position detected by the detector inside the display device and a mode of outputting the information to an outside.

9. A method of controlling a display device adapted to display an image on a display surface, the method comprising:

detecting an operation position in the display surface; and

performing a function related to an operation corresponding to an operation area in a case in which the operation area is disposed outside a display area of the image in the display surface, and the operation position detected in the detecting of an operation position is located within the operation area.

10. The method of controlling a display device according to claim 9, further comprising:

recognizing a pattern displayed in the operation area; and

making function information, which corresponds to the pattern recognized in the recognizing of a pattern, correspond to the operation area,

wherein in the performing a function, a function based on the function information corresponding to the operation area is performed in a case in which the operation position is located within the operation area.
