Abstract: A cathode ray tube provides a two-dimensional sequential scan pattern on which dots for scanning or printing are presented as spots of light provided in sequence. A single multi-scan linear raster sweep of the cathode ray tube electron beam produces a single line of dots on the scanned image or photosensitive medium. A fiber optics array with one end facing the cathode ray tube, is configured two-dimensionally in a pattern that corresponds to the sequential sweep pattern of the cathode ray tube. The trace of dots on the cathode ray tube has sufficient length to accommodate the number of dots required for the width of the finished product or scanned image. A lens positioned between the cathode ray tube and optical fiber array, focuses the cathode ray tube image onto the fiber ends with a reduction in size. At the other end of the fiber optics array, the fibers are abutted together linearly to form the desired final output line width with coherence of the fibers from input to output.

Abstract: A system for converting a printable sheet of heat-shrinkable, synthetic plastic film material into a custom-made miniature having an image thereon of a selected individual. In this system, the face or figure of the selected individual is viewed by a video camera whose output signal is applied to a high-resolution TV monitor, on the screen of which is exhibited an image of the individual. The image is transferred from the monitor to an associated printer which impresses the image on the sheet in a scale appropriate to its dimensions. The sheet is then subjected to an elevated temperature, causing the sheet to shrink uniformly, and in doing so to markedly reduce the scale of the image thereon, thereby creating on a relatively thick substrate the desired miniature.

Abstract: This invention, in the production of color photographic exposures from a color monitor display, provides correction to eliminate the spatial-color triad artifacts introduced by the display and thus provide a hard copy with fully registered color picture elements. Also, source resolution exceeding the viewable resolution of the monitor may be captured in the hard copy. A photosensitive hard copy recording medium is exposed to an image from an RGB monitor CRT display through an optical system comprising a lens and a refractive image shifter. Three video fields, each representing a primary color component of the picture, are sequentially displayed, exposed as an image, and thus recorded photographically on the medium, the image being shifted between exposures to spatially register the triad color elements, thus eliminating spatial-color artifacts associated with the monitor.

In addition, sheet-like resins cured by the exposure with the ultraviolet beam using the ultraviolet radiation projector as a light source are sequentially stacked to form a desired high-precision three-dimensional image.

By shortening the path that a beam traverses or by eliminating some addresses from the address sequence, improved operating speeds are achieved.

In this way, the resolution of a recorded image can be greater than that of the output device.
