1. A projector comprising:
- an image input unit that receives image data from an image supply device;
a light modulator that modulates light generated by a light source;
an image forming unit that forms a display image in the light modulator based on the image data;
a projection unit that projects the display image formed by the image forming unit on a projection surface;
a location detection unit that detects a pointed location with respect to the display image on the projection surface;
a coordinate calculation unit that calculates first coordinates as coordinates of the pointed location in a projection area on the projection surface;
a drawing unit that draws an image based on the first coordinates calculated by the coordinate calculation unit; and
an output unit that outputs coordinates to the image supply device based on the first coordinates.

Abstract
A display device include 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.
