Patent ID: 8878801

Claim:
A display device comprising: a display unit that displays a display image on a display surface based on image data; a location detection unit that detects a pointed location with respect to the display image on the display surface; a coordinate calculation unit that calculates first coordinates as coordinates of the pointed location in a displayable area within the display surface; a coordinate conversion unit that converts the first coordinates calculated by the coordinate calculation unit into second coordinates as coordinates in the image data; and an output unit that outputs the second coordinates obtained by the coordinate conversion unit, wherein the coordinate conversion unit converts the first coordinates calculated by the coordinate calculation unit into the second coordinates based on image location information as information indicating a location of the display image with respect to the displayable area, and when image processing is executed on the image data and a display mode of the display image on the display surface is changed, the coordinate conversion unit converts the first coordinates into the second coordinates based on the image location information changed in response to the display mode.
