ABSTRACT:
An image projection system includes an image projection device for projecting a light image onto a wall, ceiling or other designated surface. The image projection device includes a housing within which is disposed separately located light sources. The housing further includes a slot for receiving several image slides. Each image slide has multiple, separated, slide image patterns thereon and each slide image pattern is in a different location on the image slide. Each of the light sources is disposed in a light chamber such that light from one of the light sources projects through only one of the separated image patterns on the image slide. Light from light sources passing through respective slide image patterns can then intersect to project multiple superimposed images on an image viewing surface. Furthermore, an electronic controller controls the light intensity and light timing of each individual light source.
