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. During exposure, the image picture elements may be expanded, but held in registration, so as to fill the available recording medium space rather than leave a sparse matrix. Where the picture information source and medium have higher resolution limits than a real time frame display on the monitor, the apparatus may be utilized in a further sequential procedure to spatially intersperse multiple registered frames of the picture and thus produce a hard copy having resolution exceeding the frame display resolution limit of the monitor.
