摘要： In the correction of the quantity of light of a light source used in an image reader which irradiates an original document with the light source, receives the reflected light by a CCD and reads the original document image, at the time of a document moving mode in which the document moves, correction of the quantity of irradiation light of the light source is performed by reading a first standard white board which extends over the whole area in the main scanning direction, prior to the initiation of readout of the moving document, and upon initiation of readout of the moving document, a second standard white board arranged outside the document passing area is read by using the same light source, with the read operation of the moving document, and correction of the quantity of irradiation light of the light source is performed based on the reflected light from the second white board.

摘要： The document read apparatus according to the present invention has a light source unit that includes a linear first light and second light sources, both light sources aligned parallel to the sub scanning direction (moving direction). When the light source unit is scanning a book document in a second region shifted toward a side of the first light source from a center position for emitting light to the center of the document, a light quantity of the second light source becomes larger than a light quantity of the first light source. When the light source unit is scanning the book document in a third region shifted toward a side of the second light source from the center position, the light quantity of the first light source becomes larger than the light quantity of the second light source. A sum of both light quantities is controlled to be constant.
