Three dimensional display system
First Claim
1. A three dimensional display system comprising:
- a display presenting a plurality of views of a scene, each view corresponding to a viewing direction for the scene;
a rendering unit generating a respective image for each of the plurality of views, the rendering unit being capable of generating differentiated images for neighboring views containing differentiated image data providing a three dimensional depth effect when neighboring views are viewed by different eyes of a viewer;
a user processor generating a user presence estimate in response to an attempted detection of a user in a viewing area for the display system, the presence estimate including an orientation of the user; and
a data processor;
receiving the user presence estimate; and
modifying the differentiated images for the neighboring views to adapt the three dimensional effect in response to the determined orientation of the user, wherein the differentiated images are gradually transitioned over a known time from a first mode of three dimensional effect to a second mode of three dimensional effect in response to a detection of a change in the user presence estimate, the first mode of three dimensional effect corresponding to a reduced three dimensional effect relative to the second mode of three dimensional effect.

Abstract
A three dimensional display system comprises a display (207) presenting a plurality of views of a scene where each view corresponds to a viewing direction for the scene. A rendering unit (203) generates an image for each of the views. The rendering unit (203) is capable of generating differentiated images for neighboring views containing differentiated image data providing a three dimensional depth effect when neighboring views are viewed by different eyes of a viewer. A user processor (209) generates a user presence estimate in response to an attempted detection of a user in a viewing area for the display system. A 3D mode controller (213) modifies the three dimensional effect in response to the user presence estimate. For example, the display system may provide a two dimensional image when no user is present and a three dimensional image when a user is present. This may reduce discomfort experienced by viewers in suboptimal positions.

13. A method of operating a display system, the display system comprising:
-
presenting a plurality of views of a scene on a display, each view corresponding to a viewing direction for the scene; a rendering unit generating a respective image for each of the plurality of views, each view corresponding to a viewing direction for the scene, including generating differentiated images for neighboring views containing differentiated image data providing a three dimensional depth effect when neighboring views are viewed by different eyes of a viewer; and a user processor generating a user presence estimate in response to a detection of a user in a viewing area for the display system, the user presence estimate including an orientation of the user; and a data processor; receiving the user presence estimate; and transitioning the differentiated images for the neighboring views to adapt the three dimensional effect in response to the orientation of the user wherein the differentiated images are gradually transitioned over a known time from a first mode of three dimensional effect to a second mode of three dimensional effect in response to a detection of a change in a user presence, the first mode of three dimensional effect corresponding to a reduced three dimensional effect relative to the second mode of three dimensional effect. - View Dependent Claims (18)

14. A computer program product, stored on a medium that is not a transitory propagating signal or wave, said product providing to a data processor instruction for:
-
presenting a plurality of views of a scene on a display, each view corresponding to a viewing direction for the scene; generating, in a rendering unit a respective, image for each of the plurality of views, including generating differentiated images for neighboring views containing differentiated image data providing a three dimensional depth effect when neighboring views are viewed by different eyes of a viewer; generating, in a user processor, a user presence estimate in response to a detection of a user in a viewing area for the display system, the user presence estimate including an orientation of the user; and receiving in a data processor a user presence estimate in response to a detection of a user in a viewing area for the display system, the user presence estimate including an orientation of the user; and the data processor transitioning the differentiated images for the neighboring views to adapt the three dimensional effect in response to the orientation of the user wherein the differentiated images are gradually transitioned over a known time from a first mode of three dimensional effect to a second mode of three dimensional effect in response to a detection of a change in a user presence, the first mode of three dimensional effect corresponding to a reduced three dimensional effect relative to the second mode of three dimensional effect.
