Abstract
A projector moves a first imaging lens and a second imaging lens in a direction that intersects the optical axis of an imaging section to adjust the imaging range of the imaging section and moves the first imaging lens and the second imaging lens in the direction that intersects the optical axis of the imaging section to switch the imaging lens located in a position corresponding to the imaging section from one to another.
Claims10
A projector comprising:
- a projection section that projects image light;
- a first imaging lens;
- a second imaging lens;
- an imaging section that captures an image of a displayed image formed of the projected image light via the first imaging lens or the second imaging lens;
- and
- an imaging lens moving mechanism that moves the first imaging lens and the second imaging lens in a direction that intersects optical axes of the imaging lenses,
- wherein the imaging lens moving mechanism performs a lens switch action of switching the first imaging lens or the second imaging lens used by the imaging section to perform the imaging from one to another and a lens shift action of shifting the first imaging lens or the second imaging lens in a position corresponding to the imaging section.

A method for controlling a projector, the method comprising:
- moving a first imaging lens and the second imaging lens in a direction that intersects an optical axis of an imaging section that captures an image of a displayed image to adjust an imaging range of the imaging section;
- and
- moving the first imaging lens and the second imaging lens in the direction that intersects the optical axis of the imaging section to switch the first imaging lens or the second imaging lens located in a position corresponding to the imaging section from one to another.
