摘要：
A projection system includes a projector and a light emitting device that emits detection light in a direction in response to a screen. The projector detects an operation to the screen based on detection light of the light emitting device by a position detection section and switches the light emitting device between an emission mode and a non-emission mode thereof in response to state of the projector.
