Image sensor chip and image reading apparatus incorporating the same

Abstract From the Canadian patent

In an image sensor chip (A), the number N of the image reading picture elements is defined as N=n~k (other than an integer multiple of 16). The n represents the number of image signals processed as a group when the image signals from the light receiving elements are subjected to level correction on a group-by-group basis. The k is the minimum integer satisfying 0<(n~k-g~p)<n. The g is the resolution defined as the number of image reading picture elements per predetermined unit length. The p is the minimum difference between required different reading widths as calculated on the basis of said unit length. When a plurality of such image sensor chips (A) are arranged in an array, the excess …
