Abstract: For continuous tracking without noticeable skips during physical changes in head position, the intensities of all subpixels of the matrix screen are reduced in order to form intensity focuses for subpixel groups behind barrier elements, which comprise a number n of subpixels, including a subpixel reserve, in the image lines. In the case of parallel alterations, these intensity focuses are then displaced by a constant absolute value continuously through directly adjacent subpixels and also through subpixel group boundaries with different stereo image views. Distance changes involve the intensity focuses being increasingly widened or compressed relative to the screen edges. The intensities of the individual subpixels can be altered by means of simple multiplication by standardized constant or variable intensity factors which can be ascertained as a function of motion.
