Interlace and Progressive Scan Comparisons Based on Visual Perception Data

Progressive scan is favored over interlace by the computer industry and many proponents of video transmission systems because of the artifacts present in interlaced displays. Visibility of interlaced artifacts depends on the acquisition method, display, and viewing conditions. Perceived sharpness of an image is considerably less for an interlaced image than for a progressive image. The reasons for this will be explained based on visual perception data, and the differences in perceived sharpness will be quantified. All of the advantages of progressive scans can be realized with receiver signal processing of a standard interlaced transmission system provided the originating camera and final display are in progressive format. In that case, all interlaced artifacts will be removed, however, the vertical resolution will be slightly lower than with a progressive camera or film scanner.
