There is provided an image reading apparatus in which a low output mode is a mode that can be controlled in a coupling state where a low power-feeding USB device is coupled, a high output mode is a mode that can be controlled in a coupling state where a high power-feeding USB device capable of feeding power higher than the low power-feeding USB device is coupled, and a control section does not perform image reading at a second reading speed faster than a first reading speed and performs image reading at the first reading speed in the low output mode.

An information processing device includes: an obtaining unit that obtains a first classification condition for classifying a document by use of image information of an image formed on the document; an acceptance unit that accepts a second classification condition for classifying the document, the second classification condition being defined by a user; and a classification unit that applies the first classification condition and the second classification condition to the image information based on a predetermined rule of a degree of priority, and classifies the document.

An image forming apparatus includes a reading unit, an image forming unit, and a controller. The reading unit is configured to acquire image data by reading an image on a first sheet. The image forming unit is configure to form an image from the image data on a second sheet using a first color material and a second color material. The controller is configured to perform text recognition on the image data, cause the image forming unit to form text from the image data on the second sheet using the second color material, and cause the image forming unit to form portions of the image data other than the text on the second sheet using the first color material.

A method of controlling an image processing apparatus makes it possible to suppress, in an auto color selection function, color determination resulting from a minute color element of a document without troubling a user.

According to an embodiment, a detection apparatus for detecting a decoloration ink image includes an image reading unit, a decoloration unit, and a controller. The controller acquires image data using the image reading unit before decoloration that is the image data on the sheet before decoloration processing is executed by the decoloration unit. In addition, the controller determines whether or not there is a difference between the image data to be decolored and the decolored image data, thereby determining whether or not the decoloration ink is used in the sheet.

An image reading apparatus includes a tray, first sensors configured to acquire information related to a maximum size of sheets placed on the tray, a scanner configured to generate first image data for each of the sheets conveyed from the tray based on the maximum size, a sheet conveyor configured to convey the sheets placed on the tray toward the scanner, second sensors configured to acquire information related to an actual size of each of the sheets conveyed by the sheet conveyor, and a controller. The controller converts for each of the sheets having an actual size that is different from the maximum size, the first image data stored in a first memory region into second image data based on the maximum size and the actual size of the sheet, and stores the second image data in a second memory region which is different from the first memory region.

An image output apparatus includes a controller that controls display of a first setting screen including setting items of a system to be used for a setting of operation of the image output apparatus and a second setting screen including setting items of a job to be used in a setting of operation in job execution, and an image outputter that outputs an image by executing a job based on the setting of the operation in the job execution. The controller disables a selection of the setting items of the job that uses a specific function on the second setting screen when use of the specific function is prohibited on the first setting screen.

An image reading device includes a loading section, a reader, and a document feeder. The loading section receives loading of a document and an identification medium. The reader reads the document and the identification medium. The document feeder conveys the document to the reader. The loading section includes a second contact glass and a medium restriction section. The second contact glass receives loading of the identification medium. The medium restriction section restricts a position of the identification medium loaded on the second contact glass. The document being conveyed by the document feeder has opposite end portions and a central portion therebetween. The opposite end portions respectively include opposite ends of the document in a direction perpendicular to a conveyance direction of the document. Only the central portion, among the opposite end portions and the central portion, of the document comes in contact with the medium restriction section.

A predetermined image correction process is automatically performed on an image, and information for identifying that the predetermined image correction process has been performed is displayed in a state that an image having undergone the predetermined image correction process is being displayed.

A conveyance apparatus includes a separation unit configured to separate and convey a sheet, a detection unit configured to detect a floating of the sheet passing through the separation unit, and a control unit configured to stop separate conveyance by the separation unit if the detection unit detects the sheet for not less than a predetermined time and/or a predetermined count.
