Definitions

  • the present invention relates to a method and system for zooming a stereoscopic image appearing on an electronic display. More particularly, the present invention relates to a method and system for adjusting the disparity of a stereoscopic image appearing on an electronic display when a user zoom request is received.
  • the perception of depth in the planar stereo image pairs of a stereoscopic image appearing on an electronic display differs from a human's stereoscopic perception of depth in the natural world.
  • Human stereoscopic depth perception in the natural world occurs when the left and right eyes converge their visual axes to fixate on a point while simultaneously adjusting their accommodation state through muscular action changing the focal length of the lens of each eye so that points in space at and around the fixation point come into focus.
  • the fixation point projects to identical positions on each retina and therefore has zero retinal disparity. Points in front of or behind the fixation point project to different positions on the left and right retina.
  • the resulting binocular disparity between the corresponding point in the left and right retinal images provides the human brain the cues from which depth may be perceived.
  • a key physiological difference between the perception of depth in a stereoscopic image rather than a scene in the natural world is that although the left and right eye need to converge off the stereoscopic image plane to fixate points in depth their accommodation state must always keep the image plane itself in focus. This requires that the viewer be able to alter the normal link between convergence and accommodation and is one reason why images with large perceived depth may be uncomfortable to view.
  • the perceived depth in a stereoscopic image appearing on an electronic display is directly proportional to the viewing distance to a display. Accordingly, a viewer looking at the same stereoscopic image from different distances may perceive different depth. Further, the perceived depth is also directly proportional to screen disparity (the difference in the physical horizontal coordinates of corresponding points in the left-eye and right-eye images) and which varies for any given stereoscopic image if the image is displayed at different sizes. Still further, the perceived depth is inversely proportional to a viewers individual eye separation or interpupillary distance which varies from individual to individual.
  • one aspect of the invention is directed to a method for zooming a stereoscopic image appearing on an electronic display of a stereoscopic image displaying device in response to a user zoom request comprising a zoom magnitude.
  • the stereoscopic image comprises a left-eye image and a right-eye image having relative horizontal disparity and being generated by an electronic processor from stereoscopic image data stored in a memory as a left- eye image pixel map comprising left-eye pixels and a right-eye image pixel map comprising right-eye pixels.
  • the method comprises the steps of: scaling the stereoscopic image data to produce scaled stereoscopic image data in response to the user zoom request; adjusting the horizontal disparity of the scaled stereoscopic image data to produce disparity-adjusted, scaled stereoscopic image data based on a heuristic defining a relationship between the user zoom request, a predetermined stereoscopic factor and a relative horizontal shift between the left-eye pixels in the left-eye image pixel map and the right-eye pixels in the right-eye image pixel map; and generating on the display a zoomed stereoscopic image corresponding to the disparity- adjusted, scaled stereoscopic image data.

  • a user request to zoom in or out of an image or video may cause the stereoscopic device 900 to implement a heuristic in which the separation of (or retinal disparity created by) the stereoscopic image pair is adjusted in relation to the extent and direction of the zoom.
  • zoom heuristics are not limited to the method by which the stereoscopic scene is created. The artisan will understand that the heuristic is equally applicable to other well known methods for creating stereoscopic views, such as shuttering, polarization, or the use of lenticulars.

  • zooming-in on the figure 626 without a parallax adjustment creates a scene in which the figure 626 appears enlarged without a change in perceived depth, as shown in Fig. 8A and the corresponding schematic shown in Fig. 8B. Further, as shown by the hieroglyphic 626a in Fig. 8B, the zoom-in has enlarged the figure 620 to such an extent that it breaks the frame 628 of the field of view. As the user focuses on the plane 576c of the screen and attempts to accommodate the portion of the figure beyond the frame of the screen, the user's visual system may be stressed as convergence and accommodation are in conflict.

Consequently, a user viewing the scene in Fig. 9 A with red/cyan glasses would perceive that the depth of the figure has moved to the background 576a of the field of view 610.

Abstract

La présente invention concerne un procédé permettant de zoomer une image stéréoscopique apparaissant sur un écran électronique d'un dispositif d'affichage d'images stéréoscopiques. L'image stéréoscopique présente une disparité horizontale et est générée par un processeur électronique à partir de données d'images stéréoscopiques stockées dans une mémoire sous la forme d'une carte de pixels d'images de l'œil gauche et d'une carte de pixels d'images de l'œil droit. La disparité horizontale des données d'images stéréoscopiques est ajustée afin de donner des données d'images stéréoscopiques à l'échelle et à disparité ajustée sur la base d'une heuristique définissant une relation entre une requête de zoom par un utilisateur, un facteur stéréoscopique prédéfini et un décalage horizontal relatif entre la carte de pixels d'images de l'œil gauche et la carte de pixels d'images de l'œil droit. Une image stéréoscopique zoomée correspondant aux données d'images stéréoscopiques à l'échelle et à disparité ajustée est affichée.
