Abstract: 3D-enhanced 2D motion picture sequences comprise a single channel of sequential images. Each image in the channel comprises primary image content representing a scene consisting of a plurality of elements. At least some images in the channel further include temporal shadow image content, comprising a degraded and/or partially transparent image of at least one element of said primary image content corresponding to a view of said at least one element as seen in the primary image content of at least one other image from said channel. The temporal shadow content of the images varies within a series of successive images in a cyclical manner. The enhanced motion picture sequences provide a sense of 3D depth when viewed on conventional 2D displays without artificial viewing aids. Similar techniques can also be applied to enhance the 3D perception of stereoscopic motion picture sequences.

Abstract: A stereoscopic motion picture sequence comprises a first channel of sequential images intended for viewing by one of a viewer's left and right eyes and a second channel of sequential images intended for viewing by the other one of the viewer's left and right eyes. Each image in each channel comprises primary image content representing a scene consisting of a plurality of elements and ‘temporal shadow’ image content. The temporal shadow image content in a first image comprises a degraded and/or partially transparent image of at least one element of the primary image content corresponding to a view of said at least one element as seen in the primary image content of a second image from the first or second channel. The temporal shadow images provide additional cognitive cues assisting the viewer's perception of the stereoscopic image sequence as having 3D depth.
