Abstract: The invention concerns a method and device for displaying, on a monitor (11), stereoscopic video images of observed scenes. The method avoids unphysiological apparitions on the monitor (11) in image areas which are remote from the convergence plane (19) by creating a blanked-out area in which the relevant image areas are displayed differently. The invention makes it easier for users to work for lengthy periods on such monitors (11) and in particular on video stereomicroscopes.

Abstract: The invention concerns a method for the recording and reproduction of stereoscopic video images of scenes being observed, as well as a device for carrying out the method. The method makes it easier to record or reproduce images using conventional recording media. A half-image detection procedure is carried out before and/or after recording takes place to determine the association of a half-image with the corresponding frames of a left-hand or right-hand channel, or the association with each other of two frames in parallel channels.

Abstract: A method for flicker-free display of a stereo image using video techniques and digital processing, as well as a device for carrying out the method, provides enhanced image resolution and greater clarity by displaying progressively scanned frames twice within a frame period on a display. In a variant, the recording or storing of images on conventional recording media is facilitated by virtue of the fact that a half-image detection procedure is carried out before and/or after recording, thus determining the association of frames concerned with corresponding frames in a left-hand or right-hand channel or the association with each other of two frames in parallel channels.
