Provided is an image reading apparatus configured to recognize edge portions of an image of an original precisely without being influenced by the varying state of the four sides of the original. The image reading apparatus includes an image reading unit configured to read the original image by scanning the original, an edge determining unit configured to determine first edge locations at the left end and right end of the original image in a main scanning direction, an edge detector configured to detect a second edge location of the original image in a sub-scanning direction, a tilt expression calculator configured to calculate a linear expression that represents the amount of inclination of the original image with respect to the main scanning direction.

An image reading device includes an image reading portion, a detection processing portion, a determination processing portion, and a rotation processing portion. The image reading portion is configured to read an image of a document. The detection processing portion is configured to detect a face image included in a read image read by the image reading portion. The determination processing portion is configured to determine an orientation of the face image when the face image is detected by the detection processing portion. The rotation processing portion is configured to rotate the read image so as to cause the orientation of the face image determined by the determination processing portion to coincide with a predetermined specific direction when the orientation of the face image does not coincide with the specific direction.

An image reading apparatus includes a transparent document platen on which a document is to be placed, a reader configured to read an image of the document placed on the document platen, a controller configured to perform a reading mode to cause the reader to read a document tucked in a storage member, which has a transparent portion and can store the document, in a state in which the storage member in which the document is tucked is placed on the document platen so that the transparent portion contacts the document platen, and a display configured to display, in the reading mode, a screen indicating an orientation in which the storage member is to be placed on the document platen.

An image reader wherein a controller executes: a start process of starting a reading operation; a head edge detection process of detecting a document width; a first side edge detection process of detecting a side edge until an occurrence of a first change from a side edge detecting state to a side edge non-detecting state; a calculation process of calculating a continuation distance based on the document width; a second side edge detection process of detecting the side edge until an occurrence of a second change from the non-detecting state to the detecting state; a third side edge detection process of detecting the side edge until an occurrence of the first change; and an end process of ending the reading operation when the second change does not occur in a continuation range in the second detection process or when the first change occurs in the third detection process.

A system and method for aligning concurrently scanned documents, such as receipts, is accomplished on a suitable digital computing device such as a multifunction peripheral. An intelligent controller having a processor and memory operates a scan engine. One or more documents are placed, character side down, on a scanner platen. Axis data is stored and corresponds with a defined orientation of the platen, and thus a defined orientation of a scan image. The controller isolates two or more image portions from the scan image with each image portion defined by a boundary corresponding to a document. The controller detects a linearly oriented image component associated with each document image portion and reorients each image portion to generally align in accordance with each linearly oriented image component and the axis data.

The image forming apparatus includes an image reading section and a control section. The image reading section reads a document placed on a contact glass to generate image data. The control section decides whether or not the document is present at a specified position of the contact glass and, upon deciding that the document is present at the specified position, erases handwritten images from the image data of the document read by the image reading section.

An image processing apparatus includes: an image reading unit that reads an image of a document according to an instruction of an operator; an acquiring unit that acquires information on the operator performing document reading, or information on motions of the operator performed on the image processing apparatus in order to perform document reading; and a display that performs display for receiving an input for document reading, based on the line of sight, from the operator, when the information acquired by the acquiring unit satisfies a predetermined condition.

An image reading apparatus includes: a document transport route along which a document inserted into the image reading apparatus from a front side is transported backward; a reader that reads an image of the document; an ejection guide that upwardly guides the document being fed after the document is ejected backward from the document transport route; and a transport-force-applying mechanism that applies a transport force to the document. The transport force applied by the transport-force-applying mechanism to a first side of the document is greater than the transport force applied by the transport-force-applying mechanism to a second side of the document, the first side being positioned on a first-directional side in a width direction intersecting a document transport direction, the second side being positioned a second-directional side that is opposite to the first-directional side. The ejection guide is positioned asymmetrically toward the first-directional side in the width direction.

A system and method for efficiently importing scanned construction project documents (e.g., digital images of physical documents) is disclosed. The method includes receiving a digital image of a document and performing a first text recognition operation on a first portion of the digital image. The method includes in response to determining, based on the first text recognition operation, that the first portion does not include machine-readable text, generating a modified image of the document by performing an image modification operation. The image modification operation may include an orientation operation. The method further includes storing the modified image of the document in a database. The image modification operation may also include a de-skewing operation and an alignment operation.
