Abstract:
A method of acquiring simulated autostereoscopic video images of a scene to be viewed, comprising: starting from stored data including three-dimensional information about an object or the scene to be viewed on a display screen, implementing n simulated cameras, wherein n.gtoreq.3, each generating an image of said scene, and each having an optical center and a simulated sensitive surface having a center, the simulated cameras being equidistant and spaced-apart by the same inter-camera distance b which remains constant while a picture is being taken with a constant field angle, and wherein each of the simulated cameras has an axis passing through the center of its simulated sensitive surface, through its optical center, and also through a point P referred to as the simulated sharp point, situated substantially at the same distance D' from all of said simulated cameras, and further comprising generating said scene to be viewed as having a nearest point P.sub.p and a farthest point P.sub.e, and wherein the inter-camera distance b and the distance D.sub.min between the simulated set of cameras and the nearest point P.sub.p are selected in such a manner that for taking said picture and for a sharp point that varies between the nearest point P.sub.p and the farthest point P.sub.e, the angle 2.alpha. between said axes of two adjacent simulated cameras varies between a value that is not greater than 4.5.degree. for the nearest point P.sub.p of the generated scene and not less than 0.2.degree. for the farthest point P.sub.e of the generated scene, said generated scene comprising only points situated between said nearest point P.sub.p and said farthest point P.sub.e.
