Abstract
An image quality enhancement scheme is disclosed wherein the image information associated with each line of an image source is transferred to one line of an image receiving medium a plurality of times, the quality of the image information transferred to one line of the image receiving medium gradually improving following each subsequent transfer. A fiber optic cathode ray tube (CRT) transfers the image information to the image receiving medium. An electron beam generator in the CRT traces a plurality of scan lines on the inner faceplate of the CRT. The image receiving medium scrolls across the face of the CRT in synchronism with the trace of each of the scan lines on the inner faceplate thereof. The image information associated with each line of the image source is transferred to the one line of the image receiving medium via the trace of each of the plurality of scan lines. Consequently, following each such transfer via the trace of each corresponding scan line, the quality of the image recorded on said one line of the image receiving medium is gradually improved.
