Abstract
A three-dimensional image display system, based on a novel depth concept referred to as Double-D-Depth, includes a first display device (3) and at least a second display device (4) which, viewed along the system axis (9-91), are offset with respect to each other and are each intended to partially display the same two-dimensional image of a scene, while parameters which are relevant to depth representation are included in the form of an additional dedicated intensity gradation in at least one of the displayed images, and all images, together with the axial distance (.quadrature.L) in between, evoke a depth effect with a viewer (10).
