Abstract: The invention relates to a method for cancelling distortion and displacement of a three-dimensional image perceived by a viewer of an autostereoscopic display device, wherein the cancelling is performed by taking into account 1) the refraction properties of the display device; 2) the position of each pixel in the display device; and 3) the viewing position of the eyes of the viewer. In this way, the viewer can have a more realistic perception of three-dimensional virtual content. This includes e.g. an improved look-around effect for the viewer and an improved interaction of the viewer with the displayed three-dimensional virtual content. Preferably, the cancelling of the distortion and/or displacement is performed by using a refraction model for the display device.
