    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.

    摘要： An image reading apparatus includes a reading glass, a second guide member, and a control section. The reading glass and the second guide member together form a document feed path. The second guide member includes a white reference plate. The control section performs, when it is determined that shading correction image data is affected by a stain, a stain location determination of whether the stain is attached to the reading glass or the second guide member according to a tone value variation in the portion of the shading correction image data that corresponds to the stain edge, the variation being along a predetermined distance in the main scanning direction.

    摘要： An image reading apparatus of the present invention includes a photoelectric transducer that performs reading scanning along a main scanning line and reads an original, the image reading apparatus obtaining a white shading level of pixels based on an output level of the photoelectric transducer obtained when a reference white is read, obtaining a black shading level of the pixels based on an output level of the photoelectric transducer obtained when a black reference is read or obtained in a dark condition, and correcting the output level of the photoelectric transducer obtained when an original image is read with the use of the white shading level and the black shading level, and the image reading apparatus further comprising a correction unit that obtains a variation amount of the white shading level between a pixel and other pixels in the vicinity of that pixel for each of pixels on the main scanning line, determines whether the variation amount exceeds a pre-set threshold value, and when the correction unit determines that the variation amount exceeds the threshold value, corrects the black shading level of the pixel subject to that determination to increase the black shading level.
