Abstract
A position detecting device includes a light output device which outputs detection light, a detection unit, and a calibration control unit. The detection unit performs a detecting operation detecting an indication position of a first indicator on a basis of reflected light reflected by the first indicator reflecting the detection light, and a detecting operation detecting an indication position of a second indicator on a basis of light emitted by the second indicator having a light emitting function. The calibration control unit executes calibration associating the indication position of the second indicator on the basis of light emitted by the second indicator having the light emitting function with a position on a manipulation surface, and restricts output of the detection light while the calibration is executed.
