摘要： An image reading device includes a reading unit, a background member, and processing circuitry. The reading unit includes alight source to emit light to a passage area through which an object passes and an imaging device to capture reflected light of the light emitted to generate a visible image and an invisible image. The background member is disposed opposite the light source across the passage area. The processing circuitry is configured to: detect a change in an image characteristic due to a change in an optical characteristic of the reading unit, in invisible images obtained by capturing of invisible marks on the background member; determine a correction amount of an image characteristic to be used for correcting an image of the object generated by the imaging device, based on the change in the image characteristic detected; and correct the image characteristic based on the correction amount determined.

摘要： A position detection device includes a background member, a reader, and processing circuitry. The background member has a higher absorption characteristic in an invisible wavelength region than in a visible wavelength region. The reader opposite the background member irradiates a recording medium having a mark and the background member with light of a visible wavelength to output a visible image or with light of an invisible wavelength to output an invisible image. The processing circuitry is configured to: detect an end position of the recording medium and a position of the mark on the recording medium from a read image output from the reader; and select the visible or invisible image as the read image used for position detection, according to an absorption characteristic of a color material forming the mark read by the reader and an absorption characteristic of the recording medium in the invisible wavelength region.

摘要： An image reading device includes a light source configured to irradiate a subject; a reading unit configured to detect reflected light generated by a subject reflecting light emitted from the light source, to perform reading; and a control unit configured to perform turn-on control on the light source. The control unit is configured to perform the turn-on control to change a turn-on condition such that the light source is turned on during a period when at least a detection region including an image pattern on the subject passes through a reading position of a reading unit, based on position information of the image pattern of the subject in a first operation mode for reading the subject, and perform the turn-on control to make the turn-on condition of the light source constant regardless of the image pattern of the subject in a second operation mode for reading the subject.

摘要： A position sensing apparatus and a method of detecting a position. The position sensing apparatus includes a scanner configured to emit light to an object to scan an image of the object, and a position detector. In the position sensing apparatus, the scanner outputs a first result of scanning obtained by irradiating the object with visible light and a second result of scanning obtained by irradiating the object with invisible light to the position detector, and the position detector corrects the second result of scanning based on the first result of scanning, and to detect an invisible alignment image based on the corrected second result of scanning. The method includes emitting light to an object using a scanner, obtaining a first result of scanning as the scanner irradiates the object with visible light, and obtaining a second result of scanning as the scanner irradiates the object with invisible light.
