Aspects of the present disclosure provide methods and apparatuses for processing a digital image of a document, for example, to determine whether the document is a long document. An exemplary method generally includes obtaining a plurality of digital images of the document, segmenting at least a first digital image of the plurality of images into pixels associated with a foreground of the first digital image and pixels associated with a background of the first digital image, detecting a plurality of contours in the segmented first digital image, deciding, for each detected contour of the plurality of contours, whether that contour is an open contour or a closed contour, and determining that one or more sides of the document is out-of-bounds based, at least in part, on the decisions.

Aspects of the present disclosure provide methods and apparatuses for processing a digital image of a document, for example, to determine whether the document is a long document. An exemplary method generally includes obtaining a plurality of digital images of the document, determining a type of the document, loading one or more pre-defined metrics associated with the document based on the determined type of the document, determining one or more characteristics of the document based on one or more analyses performed on the plurality of digital images of the document, comparing the one or more characteristics of the document with the one or more pre-defined metrics, and determining the document to be a long document based, at least in part, on the comparison.

A carrier sheet detecting unit is located upstream a reading unit in a transport direction in which transport is performed, and can detect a carrier sheet transported. Then, a control unit can determine that the carrier sheet is transported based on a detection result of the carrier sheet detecting unit. Additionally, the reading unit can read an original document sandwiched by the carrier sheet transported, the control unit can determine that the carrier sheet is transported based on a reading result of the reading unit. Then, the control unit switches between adopting the detection result of the carrier sheet detecting unit and adopting the reading result of the reading unit, and determines that the carrier sheet is transported.

An image processing apparatus includes a processor configured to, in a case of controlling an image capturer to image a document placed in a placement area without an instruction from a user in response to detection of placement of the document in the placement area, avoid imaging of the document placed in the placement area if the document placed in the placement area is identical to a document imaged last time.

An image processing apparatus is to execute a process selected among multiple processes. The image processing apparatus includes a storage unit to store a list in which each of the processes is associated with a type of the process representing whether the process is to use information about an orientation of a document; an objective process determination unit to determine whether the selected process to be executed is of the type to use the information about the orientation of the document, based on the list stored in the storage unit; and a display control unit to display a confirmation screen on a display unit, for prompting to confirm the orientation of the document after having received an execution command for the process, in a case where the process has been determined as of the type to use the information about the orientation of the document.

A document processing device includes a scanner, a display, a notification unit, and a control unit. The scanner is configured to read a document provided on a document table. The display is configured to display image data of the document read by the scanner. The notification unit is configured to provide a notification warning to indicate that the document has not been removed from the document table. The control unit is configured to detect the document on the document table.

An image processing apparatus including a display unit includes a processor and a memory storing instructions, when executed by the processor, causing the image processing apparatus to function as a detection unit that detects occurrence of a sheet jammed inside the image processing apparatus and a display control unit that displays a screen based on detection of the occurrence of the jammed sheet. The screen includes a first region for displaying work that a user carries out to remove jammed sheets from inside the image processing apparatus and a second region for displaying work that the user carries out after removing the jammed sheets from inside the image processing apparatus.

A reading method guidance apparatus includes a receiving unit, an acquisition unit, and a guidance unit. The receiving unit receives a document size that is a size of a document as a reading target. The acquisition unit acquires an image of at least a partial area in the document. The guidance unit provides an operator with guidance about a reading procedure when the document is read by a first reading apparatus in plural batches, using a feature amount obtained from the acquired image, the received document size, and a readable size that is a size of an area readable by the first reading apparatus.

A document size detecting apparatus includes a first acquisition unit, a second acquisition unit, and a detector. The first acquisition unit acquires a first image that is an image of an entire document as a reading target. The second acquisition unit acquires a second image that is an image of a part of the document read by a first reading apparatus. The detector detects a size of the document using a result of a matching process between the first image and the second image and a read size that is a size of the second image read by the first reading apparatus.

In an image reading apparatus, a processor receives an input instructing to control the scanner to read an original, and controls the scanner to generate image data by reading the original. The processor receives device identification information identifying an information processing apparatus from the information processing apparatus. The process executes a first process and a second process. The first process includes: transmitting to a push notification server via the communication interface the received device identification information and reading information, the reading information including at least one of information specifying the controlling the scanner is start and information specifying the controlling the scanner is complete; receiving request information from the information processing apparatus via the communication interface; and transmitting the generated image data to the information processing apparatus in response to receiving the request information.
