ABSTRACT:
A laser light based image projection apparatus and method for projecting full color moving images comprising a plurality of color daub components onto a remote viewing screen comprises a source of digital image data in the form of inter-related color position co-ordinates and color intensity values at any instant in time, which digital image data are analyzed by a color value analyzer to derive therefrom specific red, blue, and green color intensity components and specific red, blue, and green color position co-ordinates. Time-based laser intensity control signals, time-based directional control signals, specific laser addresses, and projection timing parameters are calculated, and are used to produce laser actuation signals that control narrow diameter beam red, blue, and green lasers, to control optically adjusted wide diameter beam red, blue, and green lasers, and to control optically adjusted very wide diameter beam red, blue, and green lasers. The time-based directional control signals are received by a laser beam deflector and are used to direct each beam of laser light to its intended location on the remote viewing screen, so as to form corresponding color daub components. The color daub components combine together in an overlapping manner to form full color moving images. The apparatus and method of the present invention also provide the versatility of projecting an image of virtually any type onto a viewing screen that may be either a flat, curved or spherical, and be of virtually any size.
