A display device includes a generation unit that generates image data according to a position of a pointer, a communication unit that communicates with an information processing device that generates image data according to the position of the pointer, and a control unit that causes the communication unit to perform a transmission operation of transmitting image information corresponding to an image including an image indicated by the image data generated by the generation unit in a first state in which the generation unit generates the image data according to the position of the pointer, to the information processing device, when a state is switched from the first state to a second state in which the information processing device generates the image data according to the position of the pointer.

Display device, display system, and method of controlling display device

A display device includes: an input unit which has image data inputted from an image supply device; a detection unit which detects a position of an indicator and generates indicator information including information about the detected position; a setting unit which sets a mode for processing the indicator information to a first mode or a second mode; a drawing unit which draws a second image generated on the basis of the indicator information and superimposes the second image on a first image generated on the basis of the inputted image data; a selection unit which outputs the indicator information to the drawing unit if the first mode is set and outputs the indicator information to the image supply device if the second mode is set; and a drawing control unit which erases the second image if a switching from the first mode to the second mode is carried out.
