High resolution input scanner using a two dimensional detector array

Abstract From the Canadian patent

In an input scanner the subject to be scanned is translated in a cross scan direction relative to a two dimensional integrated CCD detector array, or the like so that successive full scan length segments of the subject are sequentially imaged onto the array. The photosensitive zones of the detectors within the different rows of the array are laterally staggered so that each of the detectors responds to a specific spatially predetermined resolution element or pixel of each scan line. The detectors generate data samples in response to those pixels, but the data samples representing adjacent pixels of any given scan line are distributed over multiple rows of the array in accordance with a two …
