  • Color motion depth effect system
    Patent number: 5751397
    Abstract: A method for creating the perception of visual depth in two dimensional displays. A filter or lens of one color (for example red) covers the left eye of a viewer and a lens of another color (for example green) covers the right eye. Objects moving in either lateral direction can be made to appear closer to or farther away from the viewer depending upon the color of the objects and surrounds. Objects that appear brighter to the left eye appear closer to the viewer when they are moving from left to right. These left eye bright objects appear farther away from the viewer when they are moving from right to left. The effect is reversed for objects that appear brighter to the right eye. Objects that appear brighter to the right eye appear closer to the viewer when they are moving from right to left. These right eye bright objects appear farther away from the viewer when they are moving from left to right. The colors of the areas surrounding moving objects can produce or contribute to the depth effect.
