Abstract
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.

Claim 6
Dependent Claim
15 words
The printer of claim 1 wherein said image transfer means comprises a cathode ray tube.
Claim 7
Dependent Claim
219 words
A photographic printer for transferring image data from a host computer system to expose a print media, and wherein media is moved linearly through said printer as said image is transferred to said media, said printer comprising: a memory for storing said image data; a host interface for receiving said image data transferred from said host computer system and storing said image data into said memory means; a plurality of CRT means for transferring horizontal segments of said image onto said media as said media moves vertically across said plurality of CRT means, wherein at least one of said plurality of CRT means is vertically displaced with respect to at least one other of said plurality of CRT means; and processing means operatively engaged with said memory means and with said CRT means for retrieving said image data from said memory means, for decomposing said image data into a plurality of horizontal image segments, one of said plurality of said horizontal image segments for each of said plurality of CRT means, for delaying at least one of said image segments, and for transferring said plurality of horizontal image segments to said plurality of CRT means thereby to transfer said image segments to said media, wherein said image segments are recomposed as said image segments are transferred to said media.
