Abstract

A projector provides plural display areas on a screen and respectively displays input images input from plural image sources in the respective display areas by a projection unit, and includes a location detection unit that detects a pointed location of a pointing tool on the screen, and an image processing unit that executes processing over the plural display areas according to the detected pointed location.

Claims

1. A display device comprising:

a display unit that provides plural display areas on a display surface and respectively displays input images input from plural image sources in the respective display areas;

a location detection unit that detects a pointed location on the display surface; and

a processing unit that executes processing over the plural display areas according to the pointed location detected by the location detection unit.

2. The display device according to claim 1, wherein the processing unit draws an image over the plural display areas according to the pointed location detected by the location detection unit, and superimposes and displays the drawn image on the input images by the display unit.

3. The display device according to claim 1, wherein the processing unit executes processing of enlarged or reduced display of the images being displayed in the plural display areas within the respective display areas according to the pointed location detected by the location detection unit.

4. A method of controlling a display device that displays an input image input from an image source on a display surface, comprising:

providing plural display areas on the display surface and respectively displaying input images input from plural image sources in the respective display areas;

detecting a pointed location on the display surface; and

executing processing over the plural display areas according to the detected pointed location.

5. A non-transitory computer-readable medium that stores a computer-executable program that controls a display device that displays an input image input from an image source on a display surface, allowing a computer to function as

a display unit that provides plural display areas on the display surface and respectively displaying input images input from plural image sources in the respective display areas;

a location detection unit that detects a pointed location on the display surface; and

a processing unit that executes processing over the plural display areas according to the pointed location detected by the location detection unit.
