A portable terminal has a memory having a program stored thereon and readably by a computer. The program causes the portable terminal to perform deciding an image forming apparatus enabling to execute a first operation as a first designated apparatus which executes the first operation in accordance with predetermined decision criteria, deciding an image forming apparatus designated by a user of the portable terminal as a second designated apparatus which executes a second operation different from the first operation, receiving a designation of designating at least one of the first operation and the second operation, transmitting first instruction information that instructs to execute the first operation to the first designated apparatus when the first operation is designated in the designation, and transmitting second instruction information that instructs to execute the second operation to the second designated apparatus when the second operation is designated in the designation.

An image reading apparatus includes a shooter where a first mounting surface that is inclined with respect to a horizontal plane is formed thereon, a stacker, a supporting unit that movably supports the stacker in such a manner that the stacker is arranged in a first region or a second region, a conveyance unit that conveys a document from the shooter to the stacker when the stacker is arranged in the first region, and a reading unit that reads an image from the document when the document is conveyed by the conveyance unit, wherein a surface area of a region of the first mounting surface that is covered by the stacker when the stacker is arranged in the first region is greater as compared with that when the stacker is arranged in the second region, and the stacker is formed to be capable of being lengthened or shortened.

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.

A portable terminal has a memory having a program stored thereon and readably by a computer. The program causes the portable terminal to perform deciding an image forming apparatus enabling to execute a first operation as a first designated apparatus which executes the first operation in accordance with predetermined decision criteria, deciding an image forming apparatus designated by a user of the portable terminal as a second designated apparatus which executes a second operation different from the first operation, receiving a designation of designating at least one of the first operation and the second operation, transmitting first instruction information that instructs to execute the first operation to the first designated apparatus when the first operation is designated in the designation, and transmitting second instruction information that instructs to execute the second operation to the second designated apparatus when the second operation is designated in the designation.

An image forming apparatus includes an input unit configured to input image data, an image forming unit configured to form an image on a recording material based on the input image data, a reading unit configured to read the image formed on the recording material, and a control unit configured to, based on the input image data and the image read by the reading unit, acquire a plurality of change amounts from the read image, and determine a type of an abnormal image based on a plurality of the acquired change amounts.

An image capturing method and an image capturing device using the same are provided. The image capturing method includes the following steps. Firstly, the image capturing device receives a paper sheet having a plurality of regions. Then, the image capturing device provides a user interface. Then, in response to an operation of a user to the user interface, an arrangement regulation of the regions is set. Then, the image capturing device captures a plurality of region images of the regions of the paper sheet. Then, the image capturing device arranges the region images according to the arrangement regulation.

An image forming apparatus includes an image forming unit, a display unit, an operation unit, and a controller. The controller causes, before printing an image, the display unit to reduce and display, with respect to each of setting items for printing, images to each of which a processing indicated by one of the setting items is applied. When a user designates one of the images to which the processing indicated by one of the setting items is applied, the controller accepts an instruction to print the image, reflecting the processing indicated by the setting item corresponding to a designated image, and causes the display unit to reduce and display the images to each of which the processing indicated by a remaining setting item not designated by the user, and the processing indicated by the designated setting item corresponding to the designated image, are applied, with respect to remaining setting items.

A first image forming section forms a monochromatic image with a first color material. A second image forming section forms a monochromatic image with a second color material different from the first color material. A color material selection section selects either the first color material or the second color material as a color material for image formation by a user. An acquisition section reads a document to acquire image data indicating the document. A mode selection section selects, by a user, either a first mode in which a first image processing is executed as an image processing on the image data acquired by the acquisition section or a second mode in which a second image processing, different from the first image processing, for increasing visibility of a color formed on a sheet regardless of a color material selected by the color material selection section, is executed.

An image forming apparatus to function as an input unit configured to input image data, a printing unit configured to print an image based on the image data input by the input unit, a control unit configured to perform control to, if the image forming apparatus operates in a first mode, print by the printing unit an image generated from the image data input by the input unit, and if the image forming apparatus operates in a second mode, print by the printing unit an image obtained by adding a predetermined pattern image to the image generated from the image data input by the input unit, and an accepting unit configured to, if the image forming apparatus operates in the second mode, accept selection regarding whether to perform printing in the second mode in response to operation performed to start printing the image.
