DEFINITION

Classification: 353/30

(under the class definition) Subject matter including at least one image projector to project a plurality of images on a screen in superimposed or in mosaic relationship so that the images each contribute a part of the composite image.

(1) Note. One of the images may merely be projected on the screen at intervals while the other is steadily projected. However, if one image is faded in while the other is faded out with no cooperation of the images, classification is not here but in one of subclasses 83, 86, 90 or 93, below.
