Abstract: A display of a series line organized images is provided in which the images are spread across a plurality of linearly arranged display devices and appear to be shifting from one display device to the next. The line organized images are first formed into a two dimensional display in which the images scroll along lines directed along one dimension and are wrapped from one line to the next along the other dimension. For example, the images may represent alphanumeric characters which scroll from one end of a row to the other end and, when scrolling off one row, are wrapped to the next row. This image is then expanded so that an image line fills a display device along the other dimension. This expanded image is then applied to the display devices so that each display device receives the expanded image with a predetermined shift along the one dimension relative an immediately adjacent display device.

Abstract: A video moving message system in which images are shifted one pixel width at a time from one video monitor to another. The video monitors are arranged side by side and/or stacked one over the other. Row and column counters are reassigned for a video read only memory matrix so as to enable accessing of image data stored in the read only memory through these reassigned counters. The image data is read out and sent to pixels on the video monitors which correspond to the row and counter addresses in the read only memory matrix. By reassigning during each blanking interval of a video monitor, the image on the video monitor appears to shift by at least one pixel width on the video monitor. The image is scrolled from one video monitor to the next in succession.

Abstract: A method and apparatus for displaying an interlaced image on a plurality of display screens in which the lines of two fields of the image are replicated a plurality of times in a memory to produce an enlarged image, and determined lines from both of the fields are read out of the memory and combined with other lines of the same field for the production of the display screen signals.

Abstract: A method and apparatus for displaying an interlaced image on a plurality of display screens in which the lines of two fields of the image are replicated a plurality of times in a memory to produce an enlarged image but determined lines are not read out of the memory for the production of the display screen signals, in order to maintain the original spatial relationship between the lines of the two fields. The addressing of the memory may be varied in order to obtain various special effects in the image on the display screen.
