ABSTRACT:
An image recording system includes an electro-optic image section having a luminescent display device, such as a high-resolution monochrome cathode ray tube (CRT), that successively directs its light output through a red, a green, and blue filters to expose recording film contained within a camera. The recording film can take the form of positive roll film that is processed into slides or self-developing film units. The CRT is controlled to sweep a scan line at specified line positions while modulating the output light in a digital manner and repeat the line sweep until all pixel positions for that line are properly exposed. After all lines for a particular color are imaged, the filter is changed to the next color to be imaged and the process repeated until all scan lines for the different colors are completed. The system allows very precise exposure control to create developed images having fine gradation in color density and hue.
