Abstract
Abstract A method and apparatus for improving the quality and viewing comfort of three dimensional movies and other video systems that utilize two stereoscopically related pictures by shifting corresponding object images in one or both of the pictures to positions that more nearly coincide when stereoscopically viewed such that all corresponding stereo object images in the pictures are within a viewer's limit of binocular fusion.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
76 words
A method for improving the quality and viewing comfort of stereoscopic image projection and viewing systems that utilize two pictures which have at least foreground and midground object images, comprising shifting corresponding object images in the two pictures which images are not within a viewer's limit of binocular fusion to positions that more nearly coincide when stereoscopically viewed such that all corresponding stereo object images in the pictures are within a viewer's limit of binocular fusion.
Claim 2
Independent Claim
76 words
A method for improving the quality and viewing comfort of stereoscopic image projection and viewing systems that utilize two pictures which have at least foreground and midground object images, comprising shifting corresponding object images in the two pictures which images are not within a viewer's limit of binocular fusion to positions that more nearly coincide when stereoscopically viewed such that all corresponding stereo object images in the pictures are within a viewer's limit of binocular fusion.
Claim 3
Dependent Claim
40 words
The method in accordance with claim 1 further comprising the step of filling voids caused by shifting of foreground or midground object images in one of the two pictures with appropriate picture elements from the other of the two pictures.
Claim 4
Independent Claim
128 words
A method for improving the quality and viewing comfort of stereoscopic image projection and viewing systems that utilize two pictures which have at least foreground and midground object images, comprising the steps of recordation of analog information about a picture scene having at least foreground and midground objects utilizing two stereoscopically positioned cameras; digitizing such analog information; processing such digitized information by shifting corresponding object images in the two pictures which images are not within a viewer's limit of binocular fusion to positions that nearly coincide when stereoscopically viewed so that all corresponding stereo object images in the pictures are within a viewer's limit of binocular fusion; converting the resulting processed information to analog form; and projecting the processed analog information by means of a stereo viewing system.
Claim 5
Independent Claim
128 words
A method for improving the quality and viewing comfort of stereoscopic image projection and viewing systems that utilize two pictures which have at least foreground and midground object images, comprising the steps of recordation of analog information about a picture scene having at least foreground and midground objects utilizing two stereoscopically positioned cameras; digitizing such analog information; processing such digitized information by shifting corresponding object images in the two pictures which images are not within a viewer's limit of binocular fusion to positions that nearly coincide when stereoscopically viewed so that all corresponding stereo object images in the pictures are within a viewer's limit of binocular fusion; converting the resulting processed information to analog form; and projecting the processed analog information by means of a stereo viewing system.
Claim 6
Dependent Claim
22 words
The method in accordance with claim 3 further comprising the step of utilizing motion picture cameras for said analog information recordation step.
Claim 7
Dependent Claim
21 words
The method in accordance with claim 3 further comprising the step of utilizing television cameras for said analog information recordation step.
Claim 8
Dependent Claim
174 words
An improved apparatus for providing stereoscopic image projections, comprising: a. a pair of stereoscopic cameras positioned to view a scene containing as least foreground and midground objects and to create two pictures of the scene containing object images; b. a picture digitizing system for receiving images from the stereoscopic cameras and digitizing such images; c. a digital computer picture processing system for receiving the digitized images from the picture digitizing system and processing such digital information by shifting corresponding object images in the two pictures which images are not within a viewer's limit of binocular fusion to positions that more nearly coincide when stereoscopically viewed so that all corresponding stereo object images in the picture are within a viewer's limit of binocular fusion; d. a digital to picture conversion system for receiving the processed digital data from the digital computer picture processing system and converting such data to analog image form; and e. a stereo viewing system for receiving the analog image data from the digital picture conversion system and providing visible stereo images.
Claim 9
Dependent Claim
174 words
An improved apparatus for providing stereoscopic image projections, comprising: a. a pair of stereoscopic cameras positioned to view a scene containing as least foreground and midground objects and to create two pictures of the scene containing object images; b. a picture digitizing system for receiving images from the stereoscopic cameras and digitizing such images; c. a digital computer picture processing system for receiving the digitized images from the picture digitizing system and processing such digital information by shifting corresponding object images in the two pictures which images are not within a viewer's limit of binocular fusion to positions that more nearly coincide when stereoscopically viewed so that all corresponding stereo object images in the picture are within a viewer's limit of binocular fusion; d. a digital to picture conversion system for receiving the processed digital data from the digital computer picture processing system and converting such data to analog image form; and e. a stereo viewing system for receiving the analog image data from the digital picture conversion system and providing visible stereo images.
Claim 10
Dependent Claim
47 words
The apparatus in accordance with claim 6 wherein said digital computer picture processing system is further utilized for filling picture voids caused by shifting of foreground or midground object images in one of the two pictures with appropriate picture elements from the other of the two pictures.
