Abstract: The present description concerns a lighting device comprising: an electrically-conductive support structure (130); and a plurality of elementary lighting modules (110) fastened to the support structure, each elementary module comprising a printed circuit board and, assembled on the printed circuit board, a LED assembly and an electronic circuit for powering and controlling the LED assembly, wherein, in each elementary module (110), the printed circuit board of the module comprises at least one reference terminal, the reference terminals of the printed circuit boards of the different elementary modules being electrically connected to one another via the support structure (130).

Abstract: 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; and b1) 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/or b2) assigning to said pixel position the value of the extremum identified at step a) to construct a fully focused image of the scene.
