System for displaying moving images pseudostereoscopically
First Claim
1. A system for displaying moving images pseudo stereoscopically, comprising:
- (a) a single source of sequential image information, comprising a series of source image frames adapted to be displayed sequentially over a period of time and not containing stereoscopic information captured at the origin of said series of image frames by virtue of not having been captured from two or more angles;
(b) a first means, for sequentially displaying a first series of display image frames to one of the two eyes of an observer; and
(c) a second means, for sequentially displaying a second series of display image frames to the other of the two eyes of an observer; and
(d) means for generating from said single source of sequential image information for simultaneous sequential display an image frame A of said first series of display image frames and an image frame B of said second series of display image frames, wherein said image frame A is derived from a frame F1 of said series of source image frames and said image frame B is derived from a frame F2 of said series of source image frames, wherein said frame F2 is positioned in said single source of sequential image information to be displayed after said frame F1 by an amount of time T, the amount of time T being selected such that a typical observer experiences the display as a scene having depth.

Abstract
A system for displaying moving images from image information, e.g. on videotape or disk, in the form of a series of image frames to be displayed sequentially over a period of time. The image information does not contain stereoscopic information captured at the origin. As in conventional stereoscopic display, at any particular point in time, two image frames, A and B, are displayed simultaneously, one to each of the observer'"'"'s eyes. However image frames A and B are generated from a single source of sequential image information. Image frame A is derived from a frame F1 and frame B is derived from a frame F2 of the series of source image frames. Frame F2 is positioned to be conventionally displayed after frame F1 by about 0.0167 and about 0.033 seconds. The system may include a screen on which the images are projected or otherwise displayed, the screen being at a distance D from an observer, wherein the image that is perceived by an observer upon binocular fusion of image frame A and B when their content is identical appears to be at a distance from the observer that is different from said distance D. Further detection and manipulation of the images may be performed, creating the perception that different elements within the scene appear at different depths.

13. A method for pseudo stereoscopically displaying moving images from a single source of sequential image information comprising the steps of:
-
(a) providing a series of source image frames adapted to be displayed sequentially over a period of time and not containing stereoscopic information captured at the origin of said series of image frames by virtue of not having been captured from two or more angles;
(b) sequentially displaying a first series of display image frames to one of the two eyes of an observer;
(c) sequentially displaying a second series of display image frames to the other of the two eyes of an observer; and
(d) generating from said series of source information frames for simultaneous sequential display an image frame A of said first series of display image frames and an image frame B of said second series of display image frames, wherein said image frame A is derived from a frame F1 of said series of source image frames and said image frame B is derived from a frame F2 of said series of source image frames, wherein said frame F2 is positioned in said single source of sequential image information to be displayed after said frame F1 by an amount of time T, the amount of time T being selected such that a typical observer experiences the display as a scene having depth. - View Dependent Claims (14, 15, 16, 17)
(f) continually detecting an object in successive source image frames;
(g) continually detecting a change in a property of said object in successive source image frames; and
(h) continually adjusting the display of image frame A and image frame B responsive to the detected change in said property of said object.

15. The method of claim 14, wherein:
said property is vertical position that has changed between frame F1 and frame F2 and said adjustment is modifying said image frame B derived from F2 of said series of source image frames such that said change in vertical position of said object is eliminated.
-
16. The method of claim 14, wherein:
said property is vertical position that has changed between frame F1 and frame F2 and said adjustment is modifying the value of time T to zero.
-
17. The method of claim 14, wherein:
said property is horizontal position that has changed between frame F1 and frame F2 and said adjustment reversing polarity when the change in horizontal position would result in a typical observer experiencing the display as a scene having unrealistic depth.
-
18. A three-dimensional viewing system capable of displaying a three-dimensional image to be seen by an observer, comprising the steps of:
-
taking a sequence of images not originally containing stereoscopic information by virtue of not having been captured from two or more angles;
storing at least one image in a buffer;
displaying a buffer stored image on the screen at the same time the current frame is displayed wherein two images are coded such that one image is directed to each eye of the observer, creating binocular fusion for the observer of all objects that have moved in time and space between the frames that are being simultaneously shown to the observer as well as those objects that have not.
