Method of constructing a depth map of a scene and/or a fully focused image

摘要

A method of generating, by means of a processing device, a depth map and/or a fully focused image of a scene, from a series of images of the scene taken under a same viewing angle but with a different focusing, the method including the steps of:a) for each position of a pixel in the series of images, searching for an extremum of the pixel value in the series of images; andb1) assigning to said pixel position a depth value which is a function of the rank, in the series of images, of the image where the extremum has been identified at step a) to construct a depth map of the scene, and/orb2) assigning to said pixel position the value of the extremum identified at step a) to construct a fully focused image of the scene.
