A display device includes a display portion, a display processing portion, a detecting portion, and a notification processing portion. The display processing portion displays one or more predetermined display objects on the display portion. The detecting portion detects a shielded area in the display portion shielded by a shielding object. The notification processing portion notifies by voice, among the one or more display objects, a display object that includes an area partially or completely overlapped with the shielded area detected by the detecting portion.

An image reading apparatus includes a transparent document platen on which a document is to be placed, a reader configured to read an image of the document placed on the document platen, a controller configured to perform a reading mode to cause the reader to read a document tucked in a storage member, which has a transparent portion and can store the document, in a state in which the storage member in which the document is tucked is placed on the document platen so that the transparent portion contacts the document platen, and a display configured to display, in the reading mode, a screen indicating an orientation in which the storage member is to be placed on the document platen.

The image processing system includes a reading unit configured to read an image of a document for each line to generate image data, a generation unit configured to generate a horizontal synchronization signal, the horizontal synchronization signal indicating a pixel at an initial position in each line of the image data that is generated through the reading of the image, a transmitting unit configured to transmit the image data through the reading of the document, and the horizontal synchronization signal, a receiving unit configured to receive the image data and the horizontal synchronization signal transmitted from the transmitting unit, and a requesting unit configured to request retransmission of the image data under transmission from the transmitting unit when the receiving unit receives an horizontal synchronization signal which is different from normal, wherein the transmitting unit transmits the image data in response to the request by the requesting unit.

An image reading apparatus includes: a reading unit that reads an image of a document placed on a platen for placing documents; and a display unit that displays part of the image of the document read by the reading unit in a range adjacent to a range, in which the document is placed, of the platen.

An image forming apparatus of the embodiment includes an image reading unit, a synthetic data generating unit, an image forming control unit, and a printer. The image reading unit reads an image on a sheet. The synthetic data generating unit obtains a check box to be used for determining pattern information to be added to the sheet and a management number for identifying image information from the image of the read sheet and obtains the pattern information based on the check box and the management number. The image forming control unit generates printing image information in which the pattern information is added to the image of the read sheet. The printer performs image formation based on the printing image information.

There is provided an image processing apparatus. A changing unit changes settings relative to image data generated by a reading unit for reading a document, in a case where it is not possible to store the image data in a predetermined memory. An image processing unit performs image processing on the image data generated according to the changed settings. A display displays a preview image of the image data subjected to the image processing in the case where it is possible to store the processed image data in the memory.

An image processing apparatus includes: an image reading unit that reads an image of a document according to an instruction of an operator; an acquiring unit that acquires information on the operator performing document reading, or information on motions of the operator performed on the image processing apparatus in order to perform document reading; and a display that performs display for receiving an input for document reading, based on the line of sight, from the operator, when the information acquired by the acquiring unit satisfies a predetermined condition.

In an image forming apparatus a controller receives user instruction information for printing a test chart, controls a printer to print the test chart on a sheet regardless of a result of reading mode selection, controls a display to display a screen for selecting a reading mode for reading the test chart among a plurality of reading modes, and controls a conveyance roller and a reading sensor to read the test chart on the sheet while conveying a stacked sheet in a case where a first reading mode is selected on the screen. The controller also controls the reading sensor to read the test chart on the sheet on a platen in a case where a second reading mode is selected on the screen, and controls density of the image to be printed by the printer based on a reading result of the test chart by the reading sensor.

A control apparatus includes a processor configured to: perform, on a notifier, a first control operation that, when an image of a document placed on a reader is read by the reader and a recording medium having an image formed in response to the read image is discharged into a discharge unit, starts at a notification timing a notification prompting a user to take out the document placed on the reader; and perform, on the notifier, at least one of a second control operation or a third control operation, the second control operation delaying a start of the notification if a completion of discharging the recording medium into the discharge unit is delayed with respect to a predetermined reference and the third control operation advancing the start of the notification if the completion of discharging the recording medium into the discharge unit is advanced with respect to the predetermined reference.

The image reading apparatus including a reading unit configured read an image of a document according to a read request transmitted from an external device, includes a detection unit configured to detect a state of the document to be read by the reading unit, a reception unit configured to receive a request from the external device to obtain a state of the image reading apparatus, a power supply unit configured to, in a power saving state where power supply to the reading unit and the detection unit is stopped, supply power to the detection unit based on the reception of the request, and a transmission unit configured to transmit the state of the document to be read by the reading unit detected by the detection unit to which the power is supplied by the power supply unit, to the external device as a response to the request.
