Abstract:
An image reader, comprising:n line sensors arranged in parallel in such a way that, with â€œnâ€  being an integer of 2 or more, said n line sensors have the same pixel pitch in a pixel arranging direction and are shifted at a 1/n pitch in the pixel arranging direction with respect to other line sensors; first compensating means for compensating spatial positions of said n line sensors; second compensating means for compensating a train of signals of each of said n line sensors so that a predetermined moving average of a target pixel of the signal train in one line sensor is, in a signal train of another line sensor among said n line sensors, coincident with a predetermined moving average of a target pixel corresponding to said target pixel in said one line sensor; and interleaving means for interleaving said n trains of signals which have been compensated by the second compensating means.
