Abstract
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.
Claims12
A projector that projects an image on a projection surface, the projector comprising:
- a detection section that detects an operation to the projection surface;
- and
- an emission control section that switches a mode of a light emitting section, which emits detection light that is used for detection by the detection section, between an emission mode and a non-emission mode in response to a state of the projector.
A projection system comprising:
- a projector that projects an image on a projection surface;
- and
- a light emitting device that is connected to the projector and emits detection light in a direction toward the projection surface,
- wherein the projector includes
- a detection section that detects an operation to the projection surface based on the detection light of the light emitting device, and
- an emission control section that switches a mode of the light emitting device between an emission mode and a non-emission mode in response to the state of the projector.
3 more elements
A method of controlling a projector projecting an image on a projection surface, the method comprising:
- detecting an operation to the projection surface, based on detection light emitted in a direction toward the projection surface by a light emitting section;
- and
- switching a mode of the light emitting section between an emission mode and a non-emission mode in response to a state of the projector.
