The method for generating an output video stream (1) with a view to displaying same in a two-dimensional display space (2), comprises the following steps: selecting (E1) a wide-field video stream (3); defining (E3) a desired projection (P) and a desired field of vision (cam) with a view to obtaining a particular rendering, in particular without distortion, of at least a portion of the wide-field video stream (3) in the display space (2); carrying out (E4) a first geometric function (f1) so as to generate, for each point of the display space (2), an intermediate point located in a three-dimensional reference frame, said first function taking, as parameters, the desired projection (P) and the desired field of vision (cam); and forming (E5) the output video stream from the selected wide-field stream (3), taking the intermediate points into consideration. |
