Description

ABSTRACT:
A digital film recorder, peripheral and method adapted to receive high level digital command instructions from a host computer or terminal and to develop a color hardcopy therefrom without further graphics instructions. It includes a digital input interface, local computer ROM and RAM, and a display controller for developing the graphics to be stored in a display memory. A lookup memory exchanges data between the display memory, the local computer, and the display controller and contains user preassigned color and brightness information. The output consists of a video and sync signal which may be either alternating RGB or simultaneous RGB delivered to an analog film recorder preferably incorporated as an integral part of the unit. Print command control is direct from the output of the host computer to the digital input of the digital film recorder.
