Method and apparatus for providing an image to be displayed on a screen |
摘要 |
The invention relates to a method for providing an image to be displayed on a screen 10 such that a viewer in any current spatial position O in front of the screen 10 can watch the image with only a minimal perspective deformation. According to the invention this is achieved by estimating the current spatial position O of a viewer in relation to a fixed predetermined position Q representing a viewing point in front of the screen 10 from which the image could be watched without any perspective deformation and by providing the image by applying a variable perspective transformation to an originally generated image in response to said estimated current position O of the viewer, such that the viewer in said position O is enabled to watch the image without a perspective deformation.
