An image reading apparatus includes a reader configured to read an image, and a movable member that is movable when the reader is not reading the image, and configured to move within a region where a fixed member fixed above the reader is not present on a movement trajectory of the movable member.

An image reading apparatus acquires first control data regarding generation of first rectangular image data that includes a whole of a document area corresponding to a document within a reading area of read image data. The image reading apparatus acquires second control data regarding generation of second rectangular image data that does not include a background area not corresponding to the document within the reading area of the read image data and includes at least a part of the document area.

To provide an image processing apparatus capable of correcting an orientation of a scanned image, even if the orientation of a document during scanning is incorrect. An image processing apparatus includes a document type determination unit configured to determine a document type of image data obtained by optical reading, a selection unit configured to select, based on a determination result from the document type determination unit, a determination algorithm to be applied, from a plurality of determination algorithms for determining an orientation of an image, and an orientation determination unit configured to determine an orientation of an image in the image data by using the determination algorithm selected by the selection unit.

An image forming apparatus extracts a pagination image from original document image data of each of a plurality of original documents, specifies a last-digit image corresponding to the ones place of a pagination, arrays a plurality of pagination images in a reading order of original documents beginning with an original document earliest read to form a matrix with n rows and ten columns, sets a row including ten different last-digit images as a reference row, sets a row after the reference row as a first check row, determines, in order from a first column, whether a pagination image of the first check row is a first subject pagination image differing in last-digit image from a pagination image in the identical column of the reference row, and, if determining that some pagination image or another is the first subject pagination image, determines that multi feed has occurred.

An image reading apparatus acquires first control data regarding generation of first rectangular image data that includes a whole of a document area corresponding to a document within a reading area of read image data. The image reading apparatus acquires second control data regarding generation of second rectangular image data that does not include a background area not corresponding to the document within the reading area of the read image data and includes at least a part of the document area.

An information processing apparatus includes a controller and a display. The controller is configured to (a) acquire first image data, (b) acquire multiple sets of image data, each set of image data corresponding to a reading of an object by a scanner, and (c) generate second image data corresponding to the object based on the sets image data. The display is configured to display both (a) a first image based on the first image data and (b) a second image based on the second image data, the first image being superimposed on the second image.

An image processing apparatus includes a selection unit, a determination unit, and a control unit to set candidates to be selected by the selection unit. If determination unit determines that there is not a set of a size and an orientation of a document of which the orientation cannot be correctly determined, the control unit sets, as selection unit selection candidates, candidates of sets of sizes and orientations of a plurality of documents. If the determination unit determines that there is a set of a size and an orientation of a document of which the orientation cannot be correctly determined, the control unit sets, as selection unit selection candidates, candidates obtained by excluding the set of the size and the orientation of the document of which the orientation cannot be correctly determined from the candidates of the sets of the sizes and the orientations of the plurality of documents.
