Abstract
The perception of raster lines on a television monitor is obscured by continuously and cyclically vertically shifting and presenting in successive frames the raster in successive upward positions and then in successive downward positions by incremental amounts, the total maximum vertical shift distance being less than the distance between original horizontal raster lines, thus giving the appearance of blending the information between original horizontal raster lines. Vertical raster deflection is accomplished by cyclically delaying the original, or normal, vertically sync pulses by amounts which incrementally increase to a maximum for producing a vertical frame rise less than the distance between original horizontal raster lines and decrementally decrease to no delay. A photographic camera capable of multiple frame exposure time is used to produce photographs of the video monitor without connections or operational dependence upon the television monitor system. An all-digital system provides increased reliability and repeatability as well as manufacturing and maintenance economies.
