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.

An image forming apparatus includes an apparatus body, a sheet stacking portion on which a sheet discharged from the apparatus body is to be stacked, an extension member, and an upper device. The extension member is rotatable about a rotating fulcrum between a first position at which the extension member is stored in the sheet stacking portion and a second position at which the extension member extends to downstream of the sheet stacking portion in a sheet discharge direction in which the sheet is discharged from the apparatus body. The upper device is disposed above the rotating fulcrum of the extension member and is supported to be openable by the apparatus body. The upper device in a closed state regulates a rotation of the extension member from the first position toward the second position.

An image forming apparatus includes a printing unit, a reading unit, a verification unit, and a control unit. The printing unit prints an image on a recording sheet. The reading unit reads the image printed by the printing unit. The verification unit verifies the image read by the reading unit. The control unit performs control to cause information, indicating that the image read by the reading unit is not to be verified by the verification unit, to be printed on the recording sheet with the image. When the reading unit reads the information, the control unit performs control so that the image is not to be verified by the verification unit.

A method is disclosed comprising: connecting, by a part scanner, to a blockchain platform; outputting a user interface, the user interface including at least a first input component and a second input component; capturing an image of a surface of a part; outputting the image in the user interface; generating a surface descriptor based on the image; when the first input component is activated, attempting to store, in the blockchain platform, an authentication record that is generated based on the surface descriptor, and outputting, in the user interface, an indication of an outcome of the attempt to store the authentication record in the blockchain platform; and when the second input component is activated, attempting to authenticate the part based on the surface descriptor and outputting, in the user interface, an indication of an outcome of the attempt to authenticate the part.

Provided are a printing control unit that performs control so that printing is performed in a state in which character shape deformation is made in association with meta information that is meta information acquired on the basis of print data and indicates meaning of characters, and a digitalization unit that generates meta information corresponding to character shape deformation of characters when generating digital data including character data by inputting a read image of a printed matter to generate digital data including meta information in addition to the character data. The meta information is embedded in the printed matter in an aspect of character shape deformation of characters, and when generating digital data by reading the printed matter, the character shape deformation is recognized to generate meta information corresponding to the deformation. According to this, it is possible to perform retrieval of information using the meta information and the character data.

An information processing apparatus includes an acquirer and an updater. The acquirer acquires a template document image obtained as a result of reading a template document. The updater updates, based on the template document image, processing procedure information indicating a procedure of processing including an extracting step and another step to processing procedure information indicating a procedure of processing including the extracting step and a step whose content is updated. The processing is processing to be executed based on a completed document image obtained as a result of reading a completed document generated by filling characters into the template document. The extracting step is a step of extracting a region including a character image from the completed document image.

An image reading apparatus includes a first conveyance path, a second conveyance path, an insertion/discharge port, an image reader that reads an image on a medium conveyed along the first conveyance path, and a switch that is located at a first position or a second position, wherein the switch disconnects the first conveyance path from the second conveyance path and connects the insertion/discharge port and the first conveyance path when the switch is located at the first position, and disconnects the insertion/discharge port from the first conveyance path and connects the first conveyance path and the second conveyance path when the switch is located at the second position.

In an image processing device, a sampling portion selects, as a target line, each of four reference lines that pass through a pixel of interest in a 33 target pixel group. When a difference between data among a pair of neighboring pixels, positioned along the target line, is within a predetermined first selection reference range, and with respect to at least one of two areas on both sides of the target line, all differences among data of three neighboring pixels that exist in the area are within a predetermined second selection reference range, the sampling portion selects the pair of neighboring pixels as the sample pixels. When a difference between data of the pixel of interest and an average value of the sample pixels exceeds a predetermined correction reference range, the device corrects the data of the pixel of interest to a value based on the sample average value.

An image forming apparatus that prints an adjustment pattern on a sheet includes a generator and an image former. The adjustment pattern is for correcting a color value obtained by reading a second patch region on the sheet with a second reader based on a color value obtained by reading a first patch region on the sheet with a first reader. The generator generates image data of the adjustment pattern, and the image former performs printing based on the image data. The adjustment pattern includes a first patch printed in the first patch region and a second patch printed in a region other than the first patch region in the second patch region. The second patch includes a common color patch in a same color as a color of the first patch, and a size of the first patch is larger than a size of the second patch.

A control method in a printing apparatus includes printing, by a printing unit, an adjustment image for adjusting a printing position on a sheet, conveying, by a conveying unit, the sheet on which the adjustment image is printed, reading, by a reading unit, an image to generate image data, the reading unit being executable to perform reading by a first reading method for reading an image of a sheet without conveying the sheet or a second reading method for reading the image of the sheet while conveying the sheet, and determining, based on that a type of the sheet on which the adjustment image is to be printed is a specific type, to read the adjustment image by the first reading method.
