ABSTRACT:
The present invention is aimed at reading picture image information of an original by illuminating the original with light and by receiving the transmitted or reflected light from the original. The picture image reader in accordance with the present invention includes an optical sensor for reading picture image information by receiving light from the original that is illuminated by light, a moving mechanism for relatively moving the optical sensor and the original, an overlapping mechanism for overlapping a portion of the reading region for picture images, in the reading of picture images by the optical sensor, and a synthetic picture image formation circuit for synthesizing picture image of the overlapped portion so as to have the picture image coincident with the picture image in the original, based on each picture image information that are read in overlapped manner. The overlapping mechanism comprises a control unit for controlling the moving mechanism so as to let the optical sensor read a portion of the region of picture images and/or a rod array lens arranged so as to have the images of a portion of the picture image of the original imaged in overlapped manner on the optical sensor that are composed of at least two of line image sensors. In addition, the synthetic picture image formation circuit comprises at least two of coefficient circuits for multiplying each of the picture image information of the overlapped portion with predetermined coefficients in order to weight the picture image information, and an adder for summing the weighted picture image information from each of the coefficient circuits.
