Patent Images

1. In a stereoscopic projection system which includes the projection of left and right images on a screen, a method of providing uniform illumination of both images across the entire field of the screen comprising the steps of:

  • projecting a complementary first color on the screen to define the left image;

    projecting a second, different complementary color on the screen to define the right image in a manner such that the combination of the left and right images generate a third color; and

    adjusting the illumination intensity of portions of the left and right image fields to produce uniformity of the third color over the field thereby achieving uniform illumination intensity of both left and right images across the field.
