1. A display device comprising:
- a projection unit having a light source and a light modulator, the projection unit being configured to project an image in a display area on a display surface, the image including a first display area and a second display area;
a detector configured to detect an operation position movement in at least one of a plurality of operation areas located in the display surface outside of the display area of the image, the plurality of operation areas including a first operation area located adjacent the first display area and a second operation area located adjacent the second display area; and
a controller configured to;
perform a function in the first display area and not in the second display area when the operation position movement detected by the detector is located within the first operation area, andperform the function in the second display area and not in the first display area when the operation position movement detected by the detector is located within the second operation area,wherein the detector;
obtains periodic images of an imaging area that includes the display area and an area outside the display area including the plurality of operation areas,distinguishes, based on the periodic images of the imaging area, between movements within the display area and movements outside the display area, anddetermines that a movement outside the display area is the operation position movement, andwherein the controller performs the function in both the first display area and the second display area when the operation position movement detected by the detector straddles the first operation area and the second operation area.

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.

13. A method of controlling a display device including a projection unit having a light source and a light modulator, the method comprising:
-
causing the projection unit to project an image in a display area on a display surface, the image including a first display area and a second display area; detecting an operation position movement in at least one of a plurality of operation areas located in the display surface outside of the display area of the image, the plurality of operation areas including a first operation area located adjacent the first display area and a second operation area located adjacent the second display area; performing a function in the first display area and not in the second display area when the operation position movement detected by the detector is located within the first operation area, and performing the function in the second display area and not in the first display area when the operation position movement detected by the detector is located within the second operation area, wherein the detecting of the operation position movement includes; obtaining periodic images of an imaging area that includes the display area and an area outside the display area including the plurality of operation areas, distinguishing, based on the periodic images of the imaging area, between movements within the display area and movements outside the display area, and determining that a movement outside the display area is the operation position movement, and wherein the performing of the function includes performing the function in both the first display area and the second display area when the detected operation position movement straddles the first operation area and the second operation area. - View Dependent Claims (14)
