Abstract
A projection system includes a projector body including a projection lens that projects image light, a color wheel located in a position downstream of the projection lens, a lens moving section that moves the projection lens from an initial position in at least one of an X direction and a Y direction, a movement amount detection unit that detects the amount of movement of the projection lens and the position to which the projection lens has been moved, an adjustment section that changes the position and the attitude of the color wheel, and an adjustment controller that controls the adjustment section in accordance with a detection result from the movement amount detection unit to adjust at least one of the position and the attitude of the color wheel.
Claims11
A projection system comprising:
- a projector body including a projection lens that projects an image;
- an optical filter located in a position downstream of the projection lens;
- a lens moving section that moves the projection lens from an initial position in a first direction perpendicular to the optical axis of the projection lens;
- a movement amount detector that detects at least one of the amount of movement of the projection lens from the initial position and the position to which the projection lens has been moved from the initial position;
- a filter adjuster that changes at least one of the position and the attitude of the optical filter;
- and
- an adjustment controller that controls the filter adjuster in accordance with a detection result from the movement amount detector to adjust at least one of the position and the attitude of the optical filter.
A projection system comprising:
- a projector body including a projection lens that projects an image, the projection lens including a zoom lens that moves from an initial position along an optical axis of the projection lens to enlarge/reduce the projected image;
- an optical filter located in a position downstream of the projection lens;
- a movement amount detector that detects at least one of the amount of movement of the zoom lens from the initial position and the position to which the zoom lens has been moved from the initial position;
- a filter adjuster that changes at least one of the position and the attitude of the optical filter;
- and an adjustment controller that controls the filter adjuster in accordance with a detection result from the movement amount detector to adjust at least one of the position and the attitude of the optical filter.
