An image forming apparatus includes a printing unit, a verification unit, an insertion unit, and a display unit. The printing unit prints an image on a recording sheet. The verification unit verifies the image printed by the printing unit. The insertion unit inserts an insertion sheet, on which an identifier is printed, to partition a plurality of recording sheets, on each of which the image is printed, for each bundle of a predetermined number of sheets. The display unit displays the number of recording sheets on each of which an image associated with the identifier and determined as a normal image by the verification unit is printed.

A reading device includes a visible light source to irradiate a subject with light having a visible wavelength; an invisible light source to irradiate the subject with light having an invisible wavelength; first and second image sensors to receive reflected light from the subject being irradiated with the light having the visible wavelength and the light having the invisible wavelength, and circuitry. The first image sensor generates visible image data containing a first invisible component, and the second image sensor generates invisible image data of a second invisible component. The circuitry removes the first invisible component contained in the visible image data using the invisible image data. The circuitry multiplies the invisible image data with the correction coefficient that absorbs an individual variation in removal of the first invisible component, and the correction coefficient is generated based on the visible image data and the invisible image.

An image reading device includes: an original-document table at which an original document is mounted; a reading unit configured to read the original document mounted at the original-document table; an opening/closing section configured to be able to open and close the original-document table; a power source configured to apply power for opening and closing to the opening/closing section; a proximity sensor configured to output a detection signal in accordance with approach of a detection target; and a control unit configured to control the power source on a basis of the detection signal from the proximity sensor.

There is provided a printing apparatus including an obtaining unit configured to obtain print data in which in imposition image data in which one or more images are imposed in a print region, a code for identifying each image in the imposition image data is embedded; a determination unit configured to determine an ink color to be used to print the code by excluding an ink color satisfying a predetermined condition from candidates for the ink color to be used to print the code; and a print control unit configured to print the code based on the print data obtained by the obtaining unit using a plurality of nozzle arrays for the ink color determined by the determination unit.

Provided is a method of operating an image forming apparatus. The method includes: calculating a remaining lifespan of at least one component consumed through an image forming job in the image forming apparatus; determining whether to proceed with a refill operation to refill a toner in a cartridge of the image forming apparatus, based on the remaining lifespan of the at least one component; and displaying guide information to guide the refill operation based on a result of the determining.

Aspects of the present disclosure relate to adjusting an illumination of a user depicted in one or more images when using a video conferencing application. In one example, one or more images depicting the user may be received from an image sensor. Further, an illumination of the user depicted in the one or more images may be determined to be unsatisfactory. For example, the user's face may be too bright or too dim. Accordingly, content displayed at a display device may identified and then modified. The modified content may then be rendered to a display device thereby changing the illumination of the user depicted in subsequent images. In examples, the modified content may include a graphical element, such as a ring of a specific color at least partially surrounding content rendered to and displayed at the display device.

A conveying device can selectively execute discharge processes of a plurality of discharge procedures each having a different mode of discharge to a discharge tray. An image reading portion reads images on document sheets conveyed along a conveyance path and outputs data about read images. An image reading control method includes detecting a target image that satisfies a predetermined sorting condition associated with any one of the plurality of discharge procedures from the read images. The image reading control method further includes, in a case where the target image is detected, executing a discharge control that causes the conveying device to execute the discharge process of the discharge procedure corresponding to the target image.

An image processing apparatus for inspection of a sheet on which a code image obtained by encoding predetermined information is printed includes: a first acquisition unit which acquires positional information indicating a position and a size of the code image in the sheet; a second acquisition unit which acquires a plurality of read images obtained by a plurality of reading units reading different portions of the sheet, respectively, wherein the read images become an image indicating the entire sheet by being combined; a determination unit which determines whether any one of the read images includes the entire code image based on the positional information; and an extraction unit which extracts the predetermined information by, in a case where there is a read image including the entire code image, reading the code image in that read image.

An image reading apparatus connectable to a post-processing apparatus includes an image reading unit for transmitting image data to an inspection processing unit, and a communication unit for outputting a sheet discharge timing signal to the post-processing apparatus through a signal line. The communication unit outputs the sheet discharge timing signal having different waveforms to the post-processing apparatus on the basis of an inspection result of a sheet obtained from the inspection processing unit such that the sheet discharge timing signal includes a first waveform when the sheet determined by the inspection processing unit as that there is no image abnormality is discharged and such that the sheet discharge timing signal includes a second waveform different from the first waveform when the sheet determined by the inspection processing unit as that the image abnormality occurs is discharged.

An image forming apparatus includes a forming unit, a generation unit, a storage unit, a correction unit, and a changing unit. The forming unit forms an image. The generation unit generates correction data for correcting density unevenness for each of a plurality of regions divided in a main scanning direction of an image formed by the forming unit. The storage unit stores the correction data generated by the generation unit. The correction unit corrects a density of an image to be formed by the forming unit for each of the plurality of regions based on the correction data stored by the storage unit. The changing unit changes an image formation density by the forming unit with a uniform amount of change for the plurality of regions after the correction data is generated by the generation unit.
