Abstract
Abstract A CCD pixel pattern for receiving an image to be recorded by a rotary head printer as a series of record track scans each having a predetermined curve geometry. The pixels are arranged in rows having a curvature proportional to the record track scan geometry so that the physical location of incident image light seen by each pixel will correspond directly to the physical location of the printed image increment originating with each pixel, respectively.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
91 words
In a CCD pixel array for sensing an image for subsequent recording by a rotary head printer of the type which prints a series of record tracks on a print media, wherein each of the record tracks represents a curved line segment of the image, the improvement comprising: a two-dimensional pattern of pixels defined by a plurality of spaced rows of pixels, each of said rows of pixels comprising a plurality of spaced pixels lying on a curve geometrically proportional to the curved line segment of the image to be printed.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
112 words
In an apparatus for recording an image including a CCD having a two-dimensional array of pixels, means for presenting an image to the CCD, a rotary head laser printer for scanning a series of curved record tracks on a print media, and circuit means for transferring and processing analog voltage values generated by said pixels in response to incident image light to provide a printer scan modulating signal, the improvement comprising: a pattern of pixels defined by a series of spaced rows of pixels, each of said rows of pixels comprising a plurality of spaced pixels lying on a curve geometrically proportional to said curved record tracks scanned by the laser printer.
