A processor randomly selects a page image group corresponding to a predetermined number of pages, such as five pages, from scan images of all the pages of a book, and clips a predetermined area (evaluation area) from each of the selected page images. Subsequently, the processor performs, on each clipped image, color correction and compression at a compression rate in accordance with an image quality specified via a user interface, and derives the data volume of each clipped image subjected to the processing. In addition, based on the data volumes of the clipped images subjected to the processing, the processor derives estimated one page data volumes Then, by using the estimated one page data volumes, the processor derives an estimated data volume of a digital book corresponding to the total pages of the book.

A printing system includes: a print output device arranged inside a predetermined LAN; a first server arranged outside the predetermined LAN; and an information terminal configured to transmit, to the first server, a print request indicating that a print output related to a designated file is to be performed in the print output device, wherein the first server transfers the print request to the print output device when receiving the print request from the information terminal, and the print output device generates display data of a print preview screen based on print setting included in the print request and transmits the display data to the information terminal.

Provided are an image forming apparatus capable of setting a printing size of a margin by using a preview displayed in an enlarged manner, and a non-transitory computer-readable storage medium. When a pinch-in operation performed with respect to a particular region at a left end in a whole page preview displayed on a display section has been accepted, an MFP displays a left end preview in an enlarged manner to be larger in size than the particular region at the left end in the whole page preview. When a left-to-right swipe operation performed with respect to the displayed left end preview has been accepted, the MFP sets a size specified by the swipe operation as a printing size of a margin of a page as a target of the preview, and displays a whole page preview and a left end preview, both reflecting a margin having the set size.

An image forming system including plural image forming apparatuses, being tandemly-arranged, and forming an image while assigning an area of a recording sheet, wherein each individual image forming apparatus including a display section which is configured to display various information and a control section which is configured to detect connecting positions of each individual image forming apparatus in the image forming system, and to control each individual display section to display a typical information based on detected results.

An image forming apparatus includes an operation panel, a document transport device, an image reader, and a control device. The document transport device transports a source document while a moving document reading job is being performed. The image reader reads the source document being transported by the document transport device. The control device suspends the moving document reading job, when jam occurs during the moving document reading job, and displays, on the operation panel, a preview image of the non-blank page that has been read last in the period from the start of the moving document reading job to the suspension thereof, when the page last read in the period from the start of the moving document reading job to the suspension thereof is the blank page, and the number of blank pages read is two or more.

An information processing apparatus includes a first display control unit that displays an image on a display unit, a selection unit that selects an operation image from a group of operation images used to receive different operations with respect to the displayed image, depending on a magnification of the displayed image, and a second display control unit that displays the selected operation image on the display unit.

A document reading device includes a reading section, an orientation detecting section, an orientation determining section, and a notification section. The reading section reads images of respective pages of a spread document one at a time. The orientation detecting section sequentially detects orientations of respective images read by the reading section. The orientation determining section determines whether or not the orientation detecting section detects orientation alternation between a first orientation and a second orientation opposite to the first orientation for a read image read by the reading section. The notification section notifies an error upon the orientation determining section determining that the orientation detecting section does not detect orientation alternation between the first orientation and the second orientation.

An image reading apparatus includes a read size determination circuit. The read size determination circuit has a plurality of operation mode including a first mode and a second mode. The first mode determines the size of the document detected by the first document reading unit as a first read size and determines a read size of the document set in advance as a second read size. The first read size is the read size of the document when the first document reading unit reads the document. The second mode determines the size of the document detected by the first document reading unit as the first read size. If the second document reading unit reads the document, the second mode determines the read size of the document set in the setting screen as the second read size when a start instruction of a reading job is entered using the operation circuit.

An image forming system includes a mobile terminal and an image forming apparatus capable of wirelessly communicating with each other. The mobile terminal stores therein setting information. The mobile terminal includes a first processor. The first processor performs a process of transmitting the setting information to the image forming apparatus. The image forming apparatus includes a second processor and a printing device. The second processor performs an image process on an image according to the setting information transmitted from the mobile terminal. The printing device forms the image processed by the image process on a recording medium.

An image processing apparatus is provided for scanning a medium including a scan region where target information is provided. The image processing apparatus implements processes of running an application for generating an electronic document; controlling the application to instruct a scanning device to scan the medium at a specified scan size, which is smaller than the size of the medium and includes at least the scan region, upon accepting a scan instruction from a user; controlling the scanning device to scan the medium and capture image data of the medium at the specified scan size based on the instruction from the application; executing a character recognition process on the image data captured by the scanning device to acquire the target information; and controlling the application to generate the electronic document including the target information acquired by the character recognition process input to a corresponding input field.
