Depth dependent filtering of image signal

Multi-view display device comprising:

• a display panel (1) comprising an array of display elements (20, 51), the display elements being arranged in groups, each group being associated with a view direction (φ) of an image,
• an optical element (2) for directing light emitted from the display panel, so that light emitting from a group of display elements is directed into an angular distribution (30-34) associated with the view direction of the group,
• an input module for receiving a first image signal representing a first image (50),
• a rendering module for 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 a mapping between an image element (52) of the first image and an image element (52, 55) of the second image, a strength of the spatial filter is determined by a reference depth of the first image and a depth of an image element of the first image,
• an output module for sampling the second image to a plurality of sub-images, each sub-image being associated with a view direction of the image.
