Embodiments of the present disclosure provide an image calibration method, an image forming apparatus, and a storage medium. The method includes outputting a calibration image in response to a calibration instruction, where the calibration image includes a calibration pattern and a calibration mark; according to the calibration mark of the calibration image, determining whether a calibration event corresponding to the calibration image matches a calibration event corresponding to a current calibration operation, or determining whether a calibration event type corresponding to the calibration image matches a calibration event type corresponding to a current calibration operation; and performing image calibration according to the calibration pattern in the calibration image if the calibration event corresponding to the calibration image matches the calibration event corresponding to the current calibration operation, or if the calibration event type corresponding to the calibration image matches the calibration event type corresponding to the current calibration operation.

An image processing apparatus includes an image reading portion, a position detection portion, and a print processing portion. The image reading portion is configured to read an image of a document. The position detection portion is configured to detect position information of each of check boxes included in a read image by the image reading portion. The print processing portion is configured to be able to print a position specifying image indicating the position information of each of check boxes detected by the position detection portion.

A surface object comprises a surface with a boundary, the surface having a background color. At least one optical marker is provided on the surface for assisting of image processing for improving appearance of an image of the surface with the boundary. At least one optical marker includes at least one color which is lighter or darker than the background color and the color different ΔE between the background color and the at least one color of the optical marker being between ΔE=2 and ΔE=18.

An image reading device having a mark formed on front and back of a sheet by an image forming device, and including a first scanner which reads the mark and a second scanner provided at a downstream side of the first scanner and which reads the mark, includes: a position adjusting unit configured to adjust front and back positions of the mark on the basis of a print position of the mark read by at least one of the first scanner and the second scanner; and a monitoring unit configured to monitor front and back misregistration of the mark on the basis of the front and back positions of the mark adjusted by the position adjusting unit.

A technique in the present disclosure makes it possible to accurately obtain a value selected by a user with respect to a selection-type item for which a legend is prepared in a situation where a value entered in a document is extracted from a scanned image of the document. An item name is extracted from a document image, input information input by a user is extracted from the document image, and a legend is extracted from the document image. Additionally, in a case where the input information is unsuitable as a value corresponding to the item name, the value corresponding to the item name is obtained based on the legend and the input information.

The disclosure discloses methods and systems for handling content of a document based on one or more identifiers. The method includes receiving the document having content marked using one or more starting identifiers and corresponding one or more ending identifiers, the content marked between each starting identifier and corresponding ending identifier indicates content for one of: extraction, deletion, replacement and sharing, the content in the document is marked using braille symbols. The content is marked using an erasable marking device without affecting the document. A selection of a function to be performed on the marked content is received. The document is scanned to generate a scanned document. The scanned document is analyzed to identify the one or more starting identifiers and the one or more ending identifiers. Based on the selection of the function to be performed on the marked content, perform one of: extraction, deletion, replacement and sharing.

An electronic apparatus includes a reading unit, a processing unit, and a printing unit. The reading unit scans a reading target and acquires a plurality of scanned images. The processing unit performs processing to specify an aggregation target range which is a target of aggregate printing, of the plurality of scanned images, based on the plurality of scanned images. The printing unit aggregate-prints the scanned images specified as the aggregation target range, of the plurality of scanned images.

A system and method for automatically changing the operation of a mobile device in response to a presence of information is described. In some examples, the system determines an information capture device is proximate to text, automatically changes operation of the capture device to a certain mode, captures the text, and performs an action associated with the captured text.
