Embodiment Construction

[0044] Fig. 1 schematically shows an embodiment of a display device 100 according to the invention. The display device 100 is arranged to display an output image based on the 3D vision information and the provided position information. Typically, the display device 100 is coupled to a head tracker 108 configured to determine a position 102 of a viewer 104 (ie, the viewer) relative to the display device 100 . In addition, the display device 100 includes such a head tracker 108 . The position 102 of the observer 104 may be detected by an ultrasonic tracking system, or the observer 104 may wear a magnet to indicate its position 102 to a magnetic tracking system. According to another embodiment, one or more cameras can scan the viewing area in order to determine the position of the observer, for example supplying image data to a system for recognizing the observer's eyes. According to yet another embodiment, the observer 104 wears a reflector that reflects electromagnetic energy...

Abstract

A display apparatus (100) for displaying an output image on basis of 3D visual information is disclosed. The display apparatus (100) comprises: first receiving means (101) for receiving a first signal (3DV) representing the 3D visual information; second receiving means (116) for receiving a second signal (P) representing positional information of a viewer of the output image, as function of time; filtering means (122) for high-pass filtering the second signal (P), resulting in a third signal (PF); rendering means (118) for rendering the output image on basis of the first signal (3DV) and the third signal (PF); and display means (112) for displaying the output image.

Description

technical field [0001] The invention relates to a display device for displaying output images based on 3D visual information. [0002] The invention relates to a method for displaying output images based on 3D visual information. [0003] The invention also relates to a computer program product loaded by a computer facility comprising processing means and a memory, comprising instructions for rendering an output image from 3D visual information. Background technique [0004] In the field of 3D imaging, various depth cues are known to contribute to the 3D perception. Two of them are stereoscopic viewing and interactive motion parallax. In the case of stereoscopic viewing, the viewer's eyes are presented with an image having a slightly different stereoscopic point of view than the scene being visualized. With interactive motion parallax, the stereoscopic viewpoint being visualized is adaptive relative to the viewer's head position. [0005] In the following, two examples i...
