A method of causing an observer to get an three-dimensional impression of a scene from a two-dimensional representation thereof is disclosed. The observers movements, in particular the movements of his head and/or eyes are monitored and means are provided by which, depending on these movements, two-dimensional representations uniquely associated with each position of the head and/or eyes are displayed on a screen. According to the invention, the display means represent the relative parallactic displacements between all the objects in the scene relative to a predetermined fixation point in the scene.
