<p>A three-dimensional image display system (12) includes an array of directionally-modulated pixels or light emitting picture elements DMPs (14). Each directionally-modulated pixel DMP (14) emits light which is modulated in a manner that is not uniform in all directions, to ensure that the light emitted in each included direction is appropriate for the scene being displayed. In this manner, observers (1, 2) viewing the scene from various positions see a scene generated by the image display device IDD (10) that closely simulates the three-dimensional attributes of the real objects (4, 6, 8) located in the real scene being reproduced. In one embodiment of the invention, each directionally modulated pixel (14) expressed in terms of a modulation region (16), is provided by locating a point source of light (15) behind a microminature array of liquid crystal device (LCD) elements (18), each of which are operated by a control device (54) programmed to vary the light transmission characteristics of each element (18) at a given time for passing light through that element (18) in a manner modulating the light to reproduce the intensity of the light representative of substantially the same intensity of light emitted from the actual scene at the same coordinate position.</p> |
