Abstract
A system for producing a composite image in a multiple projection system includes at least two projectors, a dynamic image shifting mechanism, associated with at least one of the two projectors, and a controller, connected to control each projector and the image shifting mechanism. Each projector is configured to project a component image to a projection surface at an image refresh rate, and the dynamic image shifting mechanism is configured to shift a projection path of the component image of the at least one projector. The controller is configured to modify image data sent to the at least one projector and to shift the dynamic image shifting device to produce a single composite image comprising the at least two component images.

11. A method for producing a composite image in a projection system having an image refresh rate, comprising the steps of:
-
projecting at least two component images to a projection surface, the component images combining to create the composite image; shifting a position on the projection surface of at least one of the at least two component images; and dynamically recalculating image data corresponding to the at least two component images, to (1) compensate for shifting of the position of the at least one component image while (2) retaining the composite image in a substantially constant position on the projection surface. - View Dependent Claims (12, 13, 14, 15, 18, 19, 20)

16. A method for combining component images in a multiple projection system, comprising the steps of:
-
projecting at least two component images to a projection surface, the component images having an overlap region and combining to create a single composite image; shifting a position on the projection surface of the at least two component images; and dynamically recalculating image data corresponding to the at least two component images, so as to compensate for shifting of position of the component images. - View Dependent Claims (17)
