A laser light based image projection apparatus and method for projecting full colour moving images comprising a plurality of colour daub components onto a remote viewing screen comprises a source of digital image data in the form of inter-related colour position co-ordinates and colour intensity values at any instant in time, which digital image data are analyzed by a colour value analyzer to derive therefrom specific red, blue, and green colour intensity components and specific red, blue, and green colour position co-ordinates. Time-based laser intensity control signals, time-based directional control signals, specific laser addresses, and projectiontiming 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 colour daub components. The colour daub components combine together in an overlapping manner to form full colour 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.
