ABSTRACT:
A system and method for producing rapid, high resolution hard color copies from computer-based graphics and image processing including a computer-controlled color video signal graphics system for producing electronically generated digital character and/or graphics data in response to programmed commands that are input to the graphics system. Thereafter, the graphics system transforms the digital data into blue, green and red color video signals which are input to a color camera system through a color control panel that is controlled by a microprocessor. The color control panel sequentially switches each of the red, blue and green video signals through to a video monitor where the signals are transformed into video images on a screen of the monitor. The video images appearing on the screen of the monitor are filtered by a color filter wheel which is also controlled by the microprocessor of the camera system. One of two types of film may be selected for exposure to the filtered video images. The video images are timed by the microprocessor so that the film medium will be exposed to each of the filtered video images for the proper length of time required to sensitize the film for each particular color of video signal. The color control panel of the camera system may also be operated to meter the brightness of the video images appearing on the screen of the monitor and to thereafter adjust the contrast and brightness of the video images.
