In an image reading device including a document platen, a document holder, multiple light sources, and a close contact type image sensor, the light sources are sequentially turned on and the image sensor individually reads light of multiple different colors reflected from a document in a main scanning direction. When the document holder is opened, in an area determination process, a first scanning area where a difference between output values of the image sensor when the light sources are sequentially turned on is within a predetermined threshold value range, and a second scanning area where the difference is outside the predetermined threshold value range are determined in an entire scanning area of the image sensor. A document size in the main scanning direction is detected based on a position of a boundary in the main scanning direction between the first and second scanning areas determined in the area determination process.

Methods and systems are presented for controlling a film transport apparatus of a film reel scanner. In one embodiment, a system is provided including a line scanning camera, a supply reel motor, a take-up reel motor, and a plurality of capstan motors. A control system may then be configured to receive and dynamically adjust position information from these motors. The control system may then provide the dynamically adjusted position information to a plurality of controllers, which may then generate control signals for the supply reel motor, the take-up reel motor, and the at least a subset of the capstan motors.

An information processing device includes a processor configured to: group electronic documents that have been processed, based on similarity degree of the electronic documents into one or more groups; determine a group, among the one or more groups, to which at least one received electronic document is to belong; determine whether the at least one received document is a modified version of one or more electronic documents belonging to the determined group, the modified version having been partially modified with respect to the one or more electronic documents belonging to the determined group; and specify a blank portion in the at least one received electronic document by comparing the at least one received electronic document with the one or more electronic documents belonging to the determined group.

An image reading apparatus includes a reading processing unit that acquires image data including an image of a document placed on a document placement unit. A first detection processing unit detects a first line image whose width or density exceeds a predetermined first threshold value from the image data. A second detection processing unit detects a rectangular area that is defined by the first line image, included in the image data, and satisfies a predetermined detection condition. A third detection processing unit detects a second line image whose width or density exceeds a second threshold value smaller than the first threshold value from the rectangular area. A fourth detection processing unit detects, as document areas of the respective documents, the rectangular area not divided by the second line image and divided areas included in the rectangular area divided by the second line image.

An image processing apparatus includes a document area extracting module configured to extract a document area from the captured image, the document area being an area of the document, a note area extracting module configured to extract a first note area from the captured image, the first note area being an area of the first note positioned at a first position of the document area of the first page, a character determining module configured to determine the first character included in the first note area by optical character recognition, a document image generating module configured to mask the first note area included in the document area, and generate a document image, a file name generating module configured to generate a file name including the first character, and a file generating module configured to generate an electronic file of the document image having the file name.

An image-reading apparatus includes a housing having a rectangular-shaped opening on a side of a reading target, a lens portion retained or housed within the housing, and a sensor element to receive light condensed by the lens portion, the light being from the reading target. Long sides of the opening include a first layer that is flat and is disposed on the side of the reading target and a second layer that is continuous with the first layer. The long sides of the opening of the housing of the image-reading apparatus has a flat surface on the side of the reading target and an interface between the first layer and the second layer that is curved.

Provided is an image forming apparatus including a printer controller configured to form an image on a sheet, a storage unit configured to store a plurality of adjustment conditions for adjusting a position on the sheet at which the image is to be formed, and a CPU. The CPU selects one of the plurality of adjustment conditions, adjusts the position at which the image is to be formed based on the selected adjustment condition, and causes the printer controller to form the image on the sheet.

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 information processing device includes a processor configured to: group electronic documents that have been processed, based on similarity degree of the electronic documents into one or more groups; determine a group, among the one or more groups, to which at least one received electronic document is to belong; determine whether the at least one received document is a modified version of one or more electronic documents belonging to the determined group, the modified version having been partially modified with respect to the one or more electronic documents belonging to the determined group; and specify a blank portion in the at least one received electronic document by comparing the at least one received electronic document with the one or more electronic documents belonging to the determined group.

A data generation system includes circuitry configured to generate data of sub-images constructing an image. Each of the sub-images includes at least one of image elements of the image. The image elements are aligned in a direction perpendicular to a given direction in which an image forming apparatus moves to form the image. The circuitry is configured to, when, in an attempt to add another one of the image elements adjacent to the at least one of the image elements in one of the sub-images, the other one of the image elements does not fit within the one of the sub-images, generate data of the one of the sub-images without the other one of the image elements.
