Abstract
A projection assembly and projection method for accurately reproducing animated and live characters, objects, and effects. The projection assembly uses a high precision robotic mirror system to achieve very high levels of image resolution, brightness, and contrast. The assembly includes a projector receiving an input image stream, and a mirror assembly is positioned proximate to the projector outlet. The mirror assembly uses positionable mirrors to reflect the projected images onto a display surface at positions that define an animation pattern on the display surface for the projected image or character. The assembly includes a motor controller assembly positioning the mirrors based on position data defining the animation pattern. The projected images may be provided in a projection area that is a fraction of the size of the display surface, such that the resolution and output light of the projector are concentrated on the display surface within this projection area.
