A THREE DIMENSIONAL DISPLAY SYSTEM

摘要

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.
