Patent ID: 6906736

Claim:
A system for enhancing a color image as perceived by a human viewer, said image being composed of a plurality of superimposed dot-patterns upon a portion of a movable curved surface having two orthogonal spatial dimensions and having curvature in only one of said dimensions, the direction of motion of said surface being in said one of said dimensions, each one of said patterns being monochromatic and different in color from color of each other of said patterns, said system comprising: means for intentionally misregistering the dots of at least one of said dot patterns with respect to the dots of at least one of said other of said patterns in directions both parallel to and perpendicular to said direction of motion to obtain a misregistration pattern; wherein said dot patterns are comprised of a plurality of dots being randomly spaced on said surface in said only one of said dimensions and being regularly spaced on said surface along the other of said dimensions; and means for controlling said misregistration pattern to obtain a particular misregistration having the property of said enhancing said color image while said particular misregistration is not perceptible to said viewer.
