Patent ID: 8624964

Claim:
A method of rendering image data for a multi-view display ( 1 ), the method comprising the steps of: receiving a first image signal representing a first image ( 50 ) comprising 3D image data not rendered for multi-view display, spatially filtering the first image signal to provide a second image signal, the second image signal representing a second image ( 53 ), the spatial filtering comprising mapping an image element ( 52 ) of the first image to a set of one or more image elements ( 52 , 55 ) of the second image, where a strength of the spatial filter is determined by a reference depth of the first image and a depth of the image element of the first image, said strength determining a size of the set of image elements, and sampling the second image to a plurality of sub-images, each sub-image being associated with a respective view direction of the image.
