Abstract
A photographic printer that uses a plurality of small CRTs to print wide format images. Within the printer, the CRTs are positioned horizontally adjacent one another but vertically displaced so that image segments displayed by adjacent CRTs either abut or overlap one another. The printer decomposes each line of the image into horizontal image segments, buffers the image segments to compensate for the vertical displacement, and displays the image segments on the CRTs such that they are exposed horizontally aligned with one another on the photographic media. The printer stitches the image at the seams between adjacent segments to reduce the discontinuities in the horizontal image rows.
