In this case, the controller accumulates the value of at least one parameter since the previous screen cleanup and, in accordance with the accumulated value of the parameter, reducing the degree of visibility of display content displayed on the screen.

An image processing apparatus includes an acquisition unit configured to acquire first image data indicating a reference image as a target print result, and second image data indicating a target image to be inspected, and a processing unit configured to inspect the target image by performing a correction on a second partial region adjacent to a first partial region to enhance the second partial region relative to a difference image representing a difference between the reference image and the target image based on the first image data and the second image data, the first partial region having a difference in between the reference image and the target image.

A motor control apparatus includes a voltage control unit and a current detection unit. The voltage control unit controls a voltage when applied to cause current to flow through the coils a motor that is detected by the current detection unit. When measurement processing is performed on a set from a plurality of sets of coils having two coils each, a first detection result is obtained by the coil current flowing from a first coil of the set to a second coil of the set. A second detection result then is obtained by the coil current flowing from the second coil to the first coil. The stop position of the rotor of the motor is determined based on the first detection result and the second detection result obtained for each of the plurality of sets of coils.

A sheet conveyance apparatus includes a sheet conveyor configured to convey a sheet, a guide configured to form a conveyance path through which the sheet is conveyed by the sheet conveyor, and a sensor disposed on a same side as the guide with respect to the conveyance path. The guide includes a retracted portion disposed over a first region in a sheet width direction perpendicular to a sheet conveyance direction, the retracted portion being retracted with respect to a second region of the guide in the sheet width direction so as not to come into contact with the sheet passing through the conveyance path, the first region including a detection region of the sensor in the sheet width direction, the second region being a sheet passing region of the sheet in the sheet width direction excluding the first region.

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.

Provided are an image forming apparatus and an inspection method of an image reading section capable of precisely detecting dirt that adheres to a dustproof glass. The image forming apparatus is provided with an image forming section, an image reading section, and a controlling section. The image reading section has a light source, a sensor, and a dustproof glass. At the time of the compensation processing operation of the image reading section, the controlling section detects dirt on the dustproof glass on the basis of a detection value acquired by the sensor when light is emitted from the light source onto a reflective member for compensation that specularly reflects the light.

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.

An image reading apparatus includes a first posture detection unit that detects a first posture that is a posture of the apparatus main body when not in use, a second posture detection unit that detects a second posture that is a posture of the apparatus main body when in use, and a posture change detection unit that detects a change in a posture of the apparatus main body. When the first posture detection unit detects a switchover of the apparatus main body to the first posture in a first power supply mode in which power is supplied to the first posture detection unit, the second posture detection unit, and the posture change detection unit, the first power supply mode transitions to the second power supply mode in which a controller supplies power to only the posture change detection unit.

An image reading apparatus includes a light source to emit at least light in a first wavelength range and light in a second wavelength range, a background member having different light reflectances in the first and second wavelength ranges, an imaging device, and circuitry. The imaging device receives reflected light from the background member irradiated with the light in the first wavelength range, and generates first read information. The imaging device further receives reflected light from the background member irradiated with the light in the second wavelength range, and generates second read information. The circuitry detects presence or absence of a first foreign substance based on a difference in reading level of the first read information generated by the imaging device; and detect presence or absence of a second foreign substance based on a difference in reading level of the second read information generated by the imaging device.
