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.

Claims

1. A moving mirror projection method, comprising:

positioning a moving mirror projection assembly proximate to a projection surface, the moving mirror projection assembly comprising a projector, an X-axis mirror and a Y-axis mirror each being rotatable about an axis and positioned to receive output light from the projector, and comprising a pair of drive motors for selectively rotating the mirrors;

operating the projector to project a stream of images including an animated object, wherein the projected stream of images is reflected from both of the mirrors and onto a projection area on the projection surface;

concurrently with the projector operating, controlling the drive motors to move the projection area to a plurality of X-Y coordinates defining an animation pattern for the animated object, whereby the animated object is animated within the projection area and is moved along with the projection area about the projection surface;

positioning a second moving mirror projection assembly proximate to the projection surface;

operating a projector of the second moving mirror projection assembly to project a second stream of images including a second animated object on a second projection area on the projection surface; and

controlling a second pair of drive motors to move a second pair of X-axis and Y-axis mirrors to move the second projection area to a plurality of X-Y coordinates defining a second animation pattern, whereby the animated object and the second animated object move independently from each other and interact on the projection surface based on the animation patterns.

2. The method of claim 1, further comprising processing a source media to obtain the stream of images and to determine a set of positions for the mirrors to provide the plurality of X-Y coordinates for the projection area based on a position of the animated object within the source media.

3. The method of claim 1, wherein the projection area has a size that is less than about one tenth of the projection surface and wherein substantially no light from the projector is projected on portions of the projection surface outside of the projection area.

4. The method of claim 1, further comprising positioning a mechanically animated element adjacent the projection surface, wherein the animation pattern is defined to cause the animated object to be positioned proximate to the mechanically animated element, and the method further comprising operating the mechanically animated element when the animated object is in the proximate position.
