1. A position detecting device, comprising:
- a camera which captures an image of a manipulation surface;
a processor configured to;
detect a manipulation position on the basis of the captured image obtained by the camera; and
execute a first calibration relevant to a manipulation position of a first indicator performing a manipulation on the manipulation surface, and a second calibration relevant to a manipulation position of a second indicator performing a manipulation on the manipulation surface,wherein, in response to completion of the first calibration, the processor provides a user interface for receiving an indication for determining whether or not the second calibration is to be executed.

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.

8. A position detecting system, comprising:
-
a position detecting device which detects a manipulation position of a first indicator and a second indicator performing a manipulation on a manipulation surface; and a light output device which outputs detection light along the manipulation surface, wherein the position detecting device includes; a camera which captures the manipulation surface, and a processor configured to; detect a manipulation position by detecting an image of light emitted by the first indicator and an image of reflected light obtained by the detection light of the light output device being reflected by the second indicator from a captured image of the camera, and execute a first calibration relevant to the manipulation position of the first indicator, and a second calibration relevant to the manipulation position of the second indicator, and in response to completion of the first calibration, the processor provides a user interface allowing indication of whether or not the second calibration is to be executed after the first calibration is executed.
