Abstract
The light incident upon a lenticular parallax panoramagram variable aspect display is imaged upon the object field and then distributed in part across portions of the object field outside the images. Adjustment is made for the rate at which the display changes as a function both of the rate of movement of the viewer past the display, and of the instantaneous absolute angular position of the viewer with respect thereto. Adjustments can also be made for parallax, lens circular aberration at off-center viewing angles, differential thermal expansions within the sign, and display changes due to changes in ambient conditions. Each lens element is preferably provided with its own exclusive object field.
