A method of generating a depth map (122) comprising depth values representing distances to a viewer, for respective pixels of an image (100), is disclosed. The method comprises: computing a cost value for a first one of the pixels (108) of the image by combining differences between values of pixels which are disposed on a path (112) from the first one of the pixels (108) to a second one of the pixels (110) which belongs to a predetermined subset of the pixels of the image; and assigning a first one of the depth values corresponding to the first one of the pixels (108) on basis of the cost value. |
