Abstract
Abstract A system and method for reproducing a plurality of images on a printer in printed form in accordance with selectable, variable multiple formats. The method generally comprises the steps of selecting a given one of a plurality of selectable, variable formats, receiving and storing digital data corresponding to each of the plurality of images except for one of the plurality of images, multiplexing the digital data corresponding to each of the plurality of images except for one with the digital data corresponding to that one of the plurality of images, and providing the multiplexed digital data to a gray line printer so as to reproduce the plurality of images in printed form in accordance with the selected format. The system includes a data input multiplexer for multiplexing digital data received in real time with digital data previously received and stored in the picture memory of the system, the multiplexed output being provided, via a high speed line memory, to a gray scale printer for reproduction of the plurality of images in the selected format. In one embodiment, a TV camera is utilized to scan the images to be reproduced, and the system includes an analog-to-digital converter for converting the video signal to digital form, and synchronization circuitry for synchronizing the receiving, storage, output and multiplexing of the digital data corresponding to each of the plurality of images to be reproduced.

Claim 3
Dependent Claim
54 words
The method of claim 1, comprising the additional steps, between steps (a) and (b), of: providing a video camera, scanning said plurality of images with said video camera to develop a video signal, and digitizing said video signal to derive said digital data corresponding to each of said plurality of images to be reproduced.
Claim 4
Dependent Claim
111 words
The method of claim 1, comprising the additional step, after step (b), of processing said digital data corresponding to each of said plurality of images to be reproduced except for one of said plurality of images so as to develop first additional digital data corresponding to a rotated version of each of said plurality of images to be reproduced except for one of said plurality of images, said method further comprising the step, after step (d) of processing said digital data corresponding to said one of said plurality of images so as to develop second additional digital data corresponding to a rotated version of said one of said plurality of images.
