Abstract: A document reader includes an image sensor. The image sensor is movable in a secondary scanning direction and rotatable about a rotational axis extending in a primary scanning direction, and obtains image information from a region facing a light-receiving surface. Rotation of the image sensor is controlled based on distance information about a distance between a document surface and a platen in such a manner as to make an image distance fall within a depth-of-field range of the image sensor.

Abstract: An image processing apparatus determines a direction of document placement relative to a scanning direction based on a direction of a shadow region in an input image when a line sensor having a light receiving element performs a scan and an image read from a book document by a reading apparatus is input. When the direction of the binding portion of the document is determined to be along a longitudinal direction of the line sensor, an image of a region read by the light receiving element of the line sensor from reflected light undergoing specular reflection from the document is detected based on the amount of variation in luminance between adjacent pixels in the read image of the book document. Luminance of the image corresponding to the region is corrected.

Abstract: A method of optimal focusing for a document scanner is disclosed. The scanner includes an optic module movable in a given scanning direction to perform scanning operation over an area of a document in a scan line by scan line manner by being driven by an optic module moving mechanism under control of a control unit. The control unit includes a best focus value memory for storage of the best focus value for each scan line. The method includes the steps of moving the optic module to one of scan lines of the document and retrieving the best focus value corresponding to the selected scan line. A focus adjusting mechanism is controlled by the control unit to move the optic module in a second direction to adjust the focus position of the optic module in accordance with the best focus value of the scan line. Once the optic module reaches the scan line, the operation of the optic module is temporarily suspended in order to have the vibration of the optic module damped out. Thereafter, a scanning operation is performed over the scan line.

Abstract: 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.
