Abstract: There is provided an image reading apparatus that is capable increasing the detection accuracy for dust, scratches, dirt, and the like. Sixty-four lines of sampling points on a reference standard white plate are read, shading correction and averaging are carried out the read image data to suppress random noise components in the image data, the data is then stored in a sampling memory, and dust detection is carried out on the data stored in the sampling memory. Alternatively, shading correction and dust detection are carried out on image data that has been subjected to linear interpolation. It is thus possible to increase the accuracy of detection of dust, scratches, dirt, and the like while ensuring that shading correction is performed at high speed.

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.
