Abstract
A projector includes a projection section that projects first light representing an image on a projection surface, a detection section that detects whether or not an enclosure member that encloses part of an area through which the first light projected via the projection section passes has been attached to the projector, and an adjustment section that adjusts the intensity of the first light based on the result of the detection performed by the detection section.
Claims8
A projector comprising:
- a projection lens that projects first light representing an image on a projection surface, the projection lens being provided in a surface of the projector;
- a switch that detects whether or not an enclosure member that encloses part of an area through which the first light projected via the projection lens passes has been attached to the surface in which the projection lens is provided;
- a light source that emits second light;
- a light modulating section that modulates the second light in accordance with image information to produce the first light;
- and
- a processor programmed to:
- in a case where optical transmittance of the projection lens is less than a first threshold, make an adjustment in which a maximum intensity of the second light in a case where the enclosure member has not been attached is made equal to a maximum intensity of the second light in a case where the enclosure member has been attached, and
- in a case where the optical transmittance of the projection lens is greater than the first threshold, make an adjustment in which the maximum intensity of the second light in the case where the enclosure member has not been attached is made lower than the maximum intensity of the second light in the case where the enclosure member has been attached.
A method for controlling a projector that projects, from a projection lens, first light representing an image on a projection surface, the projection lens being provided in a surface of the projector, the method comprising:
- detecting whether or not an enclosure member that encloses part of an area through which the first light projected from the projector passes has been attached to the surface in which the projection lens is provided;
- emitting second light;
- modulating the second light in accordance with image information to produce the first light;
- in a case where optical transmittance of the projection lens is less than a first threshold, making an adjustment in which a maximum intensity of the second light in a case where the enclosure member has not been attached is made equal to a maximum intensity of the second light in a case where the enclosure member has been attached;
- and
- in a case where the optical transmittance of the projection lens is greater than the first threshold, making an adjustment in which the maximum intensity of the second light in the case where the enclosure member has not been attached is made lower than the maximum intensity of the second light in the case where the enclosure member has been attached.
