1. A display device that displays, on a display surface, an image based on image data supplied from an image supply section, the display device comprising:

  • at least one processor that executes one or more programs to realize one or more functions of;

    a position detection unit adapted to detect an operation with a pointing body to the display surface;

    an output device adapted to output a position where the operation is performed as a pointed position when the operation is detected by the position detection unit;

    an image processing unit adapted to receive the pointed position from the output device and draw a figure so as to be superimposed on the image based on the pointed position; and

    a control section adapted to stop output of the pointed position by the output device when the operation detected by the position detection unit is an operation satisfying a condition set in advance, wherein,when the operation detected by the position detection unit is the operation satisfying the condition, the control section performs an image moving function of translating a position of the image from an original position to a translated position in accordance with a moving direction and a moving amount of the pointing body, the moving amount comprising a distance of a movement of the pointing body while the operation satisfying the condition is performed,translating a position of the figure in accordance with the moving direction and the moving amount of the pointing body such that the figure is superimposed on the image at a same position relative to the image both before and after the translating of the position of the image, andkeeping the image and the figure at their respective translated positions after the operation satisfying the condition is no longer detected, andafter performing the image moving function, the control section resumes the output of the pointed position and the image processing unit draws an additional figure based on the pointed position so as to be superimposed on the figure and the image displayed at their translated positions displayed by the display device after performing the image moving function.
