Technique for autostereoscopic image, film and television acquisition and display by multi-aperture multiplexing

Technique for auto-stereoscopic image-acquisition, generation and display by means of a screen and an optical shutter placed in front of this screen, whereby the shutter is composed of segments that can be switched from an optical transparent to an opaque state and vice versa, thus forming aperture segments through which an observer positioned within a certain distance and angular field in front of the device, views a composite of several perspectives of a scene, which have to be properly acquired or generated, as they are presented on the screen, and

• which is characterized
• by the use of a control and processing unit in order to display on the screen image composites formed from extracted partial perspective views, which are arranged adjacent and non-overlapping according to specification, whereby each partial extract of a perspective is identical to the one that would be perceived from real objects when viewed from a corresponding projection center in front of the optical shutter through a group of open aperture segments, and where a projection center is the geometric location in front of an aperture segment from which a partial extract of a perspective is determined as the set of all intersection points on the screen with lines that run from the projection point to any surface point of the viewed, virtual objects, and where the aperture segments limit the field of view on the objects, so that only partial views of a perspectives are obtained,
• and by the synchronous opening of the aperture segments while displaying the image composite, which is made up of the partial perspective extracts corresponding to the opened aperture segments,
• and by a display frame rate for the image composites that is determined by the product of the number of aperture groups and the frame rate which is in general required for a flicker free display.
