Interlace and Progressive Scan Comparisons Based on Visual Perception Data

Progressive scan is being favored over interlace by the computer industry and many proponents of video transmission systems because of the artifacts present in interlaced displays. The visibility of interlace artifacts depends on the acquisition method, the display, and viewing conditions. The perceived sharpness of an image is considerably less for an interlace image than for a progressive image. The reasons for these differences will be explained based on visual perception data. 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 as long as the originating camera and final display are in progressive format.
