Abstract: A method and a device for generating 3D images, according to which an image of a second sequence of images is generated in addition to an image of a first sequence of 2D images at an interval that can be determined via an approximation variable (?). A measure of similarity (dk) between successive images of the first sequence is determined and compared with threshold values (?0<?1<?2) so as to modify the approximation variable (?) depending thereon in such a manner that the stereo base width does not turn unnaturally large. A phase analyzer (12) is used to determine a prevailing direction of movement in successive images of the first sequence of images and a phase converter (16) is used to allocate the image of the first and second sequence of images to a left-hand or right-hand viewing channel depending on a prevailing direction of movement in successive images of the first sequence.
