Abstract
Abstract A stereoscopic graphics display system (10) has a stereoscopic window controller (18) that generates multiple windows (72 and 74) within which multiple images (76 and 78) are formed. The stereoscopic window controller directs the graphics displays system to render around each window a border (80 and 82) representing an outline of the window. Each of the borders is rendered with zero binocular disparity to assist an observer to perceive the three-dimensional qualities of stereoscopic images. Depth cue contradictions between stacked windows are reduced by rendering with zero binocular disparity the images in occluded windows.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
158 words
In a stereoscopic graphics display system having a display screen upon which an image is formed in accordance with stereoscopic image data representing right- and left-eye views of an object, the right- and left-eye views differing by a preselected amount of binocular disparity that is established by a binocular viewing model, a method of forming on the display screen plural windows within which plural images are formed, comprising: designating for each one of the windows a corresponding region of the display screen, each region including a marginal peripheral portion; assigning to each window a first binocular viewing model by which images are rendered within the region corresponding to the window and a second binocular viewing model by which a border is rendered with zero binocular disparity within the marginal peripheral portion; and rendering within the marginal peripheral portions of the regions borders that represent outlines of the corresponding windows, whereby each border is rendered with zero binocular disparity.
Claim 2
Dependent Claim
158 words
In a stereoscopic graphics display system having a display screen upon which an image is formed in accordance with stereoscopic image data representing right- and left-eye views of an object, the right- and left-eye views differing by a preselected amount of binocular disparity that is established by a binocular viewing model, a method of forming on the display screen plural windows within which plural images are formed, comprising: designating for each one of the windows a corresponding region of the display screen, each region including a marginal peripheral portion; assigning to each window a first binocular viewing model by which images are rendered within the region corresponding to the window and a second binocular viewing model by which a border is rendered with zero binocular disparity within the marginal peripheral portion; and rendering within the marginal peripheral portions of the regions borders that represent outlines of the corresponding windows, whereby each border is rendered with zero binocular disparity.
Claim 3
Dependent Claim
89 words
The method of claim 1, further comprising: detecting each region that corresponds to multiple ones of the windows; assigning a display priority to each one of the windows to which the detected region corresponds, the display priorities ranging from a highest display priority to a lowest display priority; and rendering about each detected region the border of the window that has a higher display priority that the display priority of any other window to which the region corresponds, thereby occluding in the region each window of lower display priority.
Claim 4
Dependent Claim
57 words
The method of claim 2 in which a window of lower display priority is occluded by a window of higher display priority, the method further comprising assigning to the window of lower display priority a binocular viewing model having zero binocular disparity, thereby to reduce depth cue contradictions between the windows of higher and lower display priorities.
Claim 5
Dependent Claim
89 words
The method of claim 2 in which a window of lower display priority is occluded by window of higher display priority and in which the binocular viewing models are capable of establishing either negative binocular disparity of positive binocular disparity so that images appear to be, respectively, in front of or behind the display screen, the method further comprising assigning the window of lower display priority a binocular viewing model having positive binocular disparity, thereby to reduce depth cue contradictions between the windows of higher and lower display priorities.
Claim 6
Dependent Claim
103 words
A stereoscopic graphics display system, comprising: a display screen upon which an image is formed in accordance with stereoscopic image data representing right- and left-eye views of an object, the right- and left-eye views differing by a preselected amount of binocular disparity that is established by a binocular viewing model; and stereoscopic window controlling means for forming on the display screen plural windows in corresponding display screen regions that include marginal peripheral portions and for rendering borders defining the marginal peripheral portions in accordance with binocular viewing models with zero disparity and images within the windows in accordance with preassigned binocular viewing models.
Claim 7
Dependent Claim
103 words
A stereoscopic graphics display system, comprising: a display screen upon which an image is formed in accordance with stereoscopic image data representing right- and left-eye views of an object, the right- and left-eye views differing by a preselected amount of binocular disparity that is established by a binocular viewing model; and stereoscopic window controlling means for forming on the display screen plural windows in corresponding display screen regions that include marginal peripheral portions and for rendering borders defining the marginal peripheral portions in accordance with binocular viewing models with zero disparity and images within the windows in accordance with preassigned binocular viewing models.
Claim 8
Dependent Claim
105 words
The system of claim 5 in which the stereoscopic window controlling means further comprises means for detecting each region that corresponds to multiple ones of the windows; for assigning a display priority to each one of the windows to which the detected region corresponds, the display priorities ranging from a highest display priority to a lowest display priority; and for directing the display system to render about each detected region the border of the window that has a higher display priority than the display priority of any other window to which the region corresponds, thereby occluding in the region each window of lower display priority.
Claim 9
Dependent Claim
62 words
The system of claim 6 in which a window of lower display priority is occluded by a window of higher display priority, the stereoscopic window controlling means further comprising means for assigning to the window of lower display priority a binocular viewing model having zero binocular disparity, thereby to reduce depth cue contradictions between the windows of higher and lower display priorities.
Claim 10
Dependent Claim
94 words
The system of claim 6 in which a window of lower display priority is occluded by window of higher display priority and in which the binocular viewing models are capable of establishing either negative binocular disparity or positive binocular disparity so that images appear to be, respectively, in front of or behind the display screen, the stereoscopic window controlling means further comprising means for assigning the window of lower display priority a binocular viewing model having positive binocular disparity, thereby to reduce depth cue contradictions between the windows of higher and lower display priorities.
