Abstract
A linear image sensor includes N arrays of photoelectric converting pixels, wherein N is an even integer at least equal to 2. Each array is formed by arranging, with a predetermined pixel pitch in a first direction of the array, a plurality of pixels, and each of the pixels is so shaped that the area per unit length of the pixel decreases progressively from the center of the pixel both in the first direction of the array and in a second direction perpendicular to the first direction. The N arrays themselves are provided with a mutual distance from each other of M/2 times the pixel pitch in the second direction and are mutually displaced by 1/N of the pixel pitch in the first direction so as to form a mutually interpolating arrangement, wherein M is a positive integer equal to at least 1 and wherein M and N are independent of each other.
