A system for computing a depth map comprising depth values representing distances to a viewer for respective pixels of an image. The system comprises an optimization unit () for determining a minimal depth related cost value of a current pixel, among a plurality of candidate cost values, wherein at least one of the candidate cost values is based on a depth related cost value of at least one pixel in a local neighborhood of the current pixel and on a difference between a color attribute of the at least one pixel in the local neighborhood and a corresponding color attribute of the current pixel, and at least one of the candidate cost values is based on a depth related cost value relating to at least one pixel outside the local neighborhood and on a difference between a color attribute of the at least one pixel outside the local neighborhood and a corresponding color attribute of the current pixel.

Computing a depth map

A method of rendering views for a multi-view display device () is disclosed. The multi-view display device () comprises a number of display means () for displaying respective views in mutually different directions relative to the multi-view display device (). The method comprises: computing a first motion vector field on basis of a first input image of a time sequence of input images and a second input image of the time sequence of input images; computing a first motion compensated intermediate image on basis of the first motion vector field, the first input image and/or the second input image; and providing the first motion compensated intermediate image to a first one of the number of display means ().

Rendering views for a multi-view display device

A method of combined exchange of image data and related depth data is disclosed. The method comprises: converting an input image signal, representing the image data, comprising a predetermined number of input color components (R,G,B) into an output image signal comprising a luminance component and a chrominance component; combining the output signal with the related depth data into a combined signal, comprising the luminance component, the chrominance component and a depth component (D) which is based on the depth data; and transmission of the combined signal over a number of channels (-) which is equal to the predetermined number of input color components (R,G,B).
