Abstract:
A projector includes a position detection unit and a calibration control unit. The calibration control unit executes first calibration relevant to a manipulation position of an indicator performing a manipulation on a screen, and second calibration relevant to a manipulation position of an indicator performing a manipulation on the screen. Then, the calibration control unit provides a user interface allowing indication of whether or not the second calibration is to be executed after the first calibration is executed.
