An information processing apparatus includes: a processor is configured to: read an image of at least one of a first surface or a second surface of a medium with the medium folded; discriminate whether the image is of the first surface or the second surface based on an identification image in the image; specify, based on the image, a surface on which a folding deviation occurs; and determine a correction direction of the folding deviation according to whether the surface on which the folding deviation occurs is the first surface or the second surface.

An information processing apparatus includes: a processor configured to: acquire information on a folding manner in which a folding device folds a medium; and when the folding manner does not allow reading of a folding position of the medium with the medium folded, cause a display to display information so as to prompt a user to unfold and read the medium.

A nail production system according to an embodiment of the disclosure includes a first correction section and a first conversion section. The first correction section corrects shape data of an existing nail tip or an existing nail sticker on the basis of measurement data of a nail, to thereby generate shape data of an original nail tip or an original nail sticker. The first conversion section converts the shape data of the original nail tip or the original nail sticker that is generated by the first correction section into print data.

An image forming system includes: an image forming apparatus; and a recording material information detecting apparatus provided outside the image forming apparatus, wherein the recording material information detecting apparatus includes a recording material information detector that detects recording material information about a recording material, and the image forming apparatus includes: an image former; an operation detector; and a hardware processor.

An information processing apparatus includes: a processor is configured to: read an image of at least one of a first surface or a second surface of a medium with the medium folded; discriminate whether the image is of the first surface or the second surface based on an identification image in the image; specify, based on the image, a surface on which a folding deviation occurs; and determine a correction direction of the folding deviation according to whether the surface on which the folding deviation occurs is the first surface or the second surface.

An image reading apparatus including: a conveyor that conveys a sheet on which an image is formed by an image forming apparatus; a reader that reads the sheet conveyed by the conveyor, by using a contact image sensor; and a first hardware processor that extracts an edge of the sheet by analyzing a read image by the reader, calculates a blur amount of the edge based on the extracted edge, and calculates a curl amount of the sheet based on the calculated blur amount.

An information processing apparatus includes a processor configured to: obtain characteristic values including smoothness and basis weight of a recording medium; and identify the type of the recording medium on the basis of the smoothness and the basis weight.

An image reading apparatus includes: a conveyance unit configured to convey the original; an image reading unit configured to read an image of the original conveyed by the conveyance unit by using a reading sensor to generate image data which represents a reading result; at least one processor configured to: detect a streak image in an image represented by the image data based on the image data; determine a content area in the image represented by the image data, the content area being an area where content is printed, and perform correction processing for removing the streak image by correcting the image data; wherein the at least one processor is configured to be operable in a first reading mode in which the correction processing is performed to image data corresponding to the streak image in an area outside the content area.

An image forming apparatus includes: an image forming unit configured to form an image onto a sheet; a conveyance roller configured to convey the sheet through a conveyance path, the conveyance path including a curved path being bent; a sensor configured to read the image formed on the sheet conveyed through the conveyance path by the conveyance roller, the sensor being configured to read the image formed on the sheet when a part of the sheet is conveyed through the curved path; and a controller configured to obtain information related to a type of the sheet, and to control, based on the information, a conveying speed of the sheet conveyed by the conveyance roller when the sensor reads the image.

An image forming apparatus includes a post-processing device that folds a paper on which an image is formed, a document scanner that scans a document, and a hardware processor. The hardware processor acquires image data output by the document scanner scanning a region that includes a contour of the document with a folding line formed by being folded by the post-processing device, and determines a relative position of the contour and the folding line of the document based on the image data.
