Abstract
In an image input scanner, image information is acquired by sensing light from an image at an array of photosites arranged across a path of relative movement of the array and the image. To obtain resolution k, given a nominal slow scan velocity v for the relative movement between the array and the image, slow scan velocity is varied continuously over a range of 1/2 v to v. In combination, with variation of slow scan velocity over the range of 1/2 v to v, a limited scan line throw away scheme is matched to the range of velocity, where the ratio of lines kept to lines discarded in a group of lines is defined by the ratio 1:N where for every N lines, a pattern is repeated which passes 1 line of N lines, where N is a positive integer.
