ABSTRACT:
A means and method of generating disparate information for imparting depth perception to an image. An image is formed with a shadow from a plurality of energy sources. The energy sources each having a different locus. In one embodiment, using only two energy sources the image is detected by an image detector which permits the portion of the shadow formed by one energy source to be distinguished from the portion of the shadow formed by another source. In either a static-imaging system such a still photograph or a dynamic system, such as television, means are provided for optically segregating the shadows viewed by each eye. In a monocular version of the dynamic imaging system, such as a motion picture film, a three-dimensional perception is created by successively displaying images formed with different shadows.
In a particular embodiment (of the present invention), a filter is provided for a conventional camera flash system. The filter comprises two light transmitting segments separated by an opaque segment. One light transmitting segment comprises a red filter while the other comprises a cyan filter. Thus, light from the flash source takes the form of two essentially complimentary wave bands eminating from distinct and separate sources. An image of an object taken before a screen using such system is formed with a separate shadow created by each of these sources. When viewed with the naked eye, the image has a substantially conventional appearance, but when viewed through a red filter in front of one eye and a cyan filter in front of the other, the image gives rise to a three dimensional effect.
