Rendering of Image Data for Multi-View Display
First Claim
1. Method for rendering image data for a multi-view display, the method comprising the steps of:
- provide view-dependent image data for an image,determine a view-dependent intensity function for the image,apply a spatial filtering to a view-dependent coordinate of the intensity function,sample the view-dependent intensity function to a plurality of sub-images, each sub-image being associated with a view-direction of the image.

Abstract
The invention pertains to rendering of image data for a multi-view display, such as image data for a lenticular auto-stereoscopic display. The method comprising the steps of providing view-dependent image data for an image, determining a view-dependent intensity function, or luminance function, for the image, applying a spatial filtering to a view-dependent coordinate of the intensity function, the spatial filtering being such as a low-pass filter, a high-pass filter or a combination of a low-pass and a high-pass filter, and sampling the view-dependent intensity function to a plurality of sub-images, each sub-image being associated with a view-direction of the image.

13. Multi-view display device comprising:
-
a display panel comprising an array of display elements, the display elements being arranged in groups, each group being associated with a view-direction of an image, an optical element for directing light emitted from the display panel, so that light emitting from a group of display elements is directed into an angular distribution associated with the view-direction of the group, an input module for receiving view-dependent image data for an image, a rendering module for determining a view-dependent intensity function for the image and for applying a spatial filtering to a view-dependent coordinate of the intensity function, an output module for outputting the view-dependent intensity function to a plurality of sub-images, each sub-image being associated with a group of display elements and a view-direction of the image.
