摘要

A method of generating an occlusion image property map for an occlusion viewing position for a three dimensional scene is provided. The occlusion image property map comprises at least some image property values that are occluded from the occlusion viewing position. The method utilises an algorithm which can generate an image property map for an image representing the scene as a function of a viewing position. The method generates (701, 703) image property map for different viewing positions by performing the algorithm for these positions. The occlusion image property map is generated (705) from the image property maps of different viewing positions. Specifically, the image property maps may in some examples be shifted to the occlusion viewing position and data of the occlusion image property map is then selected as a pixel from the shifted image property maps which does not correspond to the most forward pixel (unless all pixels have equal depth).
