<p>CATHODE RAY TUBE DISPLAY SYSTEM WITH MINIMIZED DISTORTION FROM ALIASING In a cathode ray tube display system in which objects to be displayed are represented by digital signals, a technique is employed to reduce distortion caused by aliasing. The objects to be displayed are represented in a memory by transition specifications which represent the object to be displayed by defining the character or the edges of the object to be displayed. From the transition specifications, a video signal is generated and applied to the cathode ray tube display device to display the object represented by the stored transition specifications. The circuitry generating the video signal causes the video to change in steps across the width of a transition from the brightness prior to the edge to the final brightness of the other side of the edge with the width of the transition varying in accordance with the slope that the edge makes with the raster scan line.</p> |
