Abstract
This invention relates to the photographic reproduction of color or monochromatic still pictures as displayed on the face of a cathode-ray tube (CRT). The invention combines the arts of television and photographics to make possible the retention of still color photographs (slides) from a television screen. A "frame grabber" is used to stop the motion of a television image and hold it while a simple color photographic process captures it.
