According to one embodiment, an image reading apparatus includes a light emitting unit, a first carriage, a first photoelectric conversion unit, a first lens, and a second carriage. The light emitting unit irradiates a reading object with light. The first carriage includes a first optical member for guiding reflected light from the reading object. The first carriage is movable in a sub-scanning direction along the reading object. The first photoelectric conversion unit receives the reflected light from the reading object guided through the first optical member and outputs an image signal. The first lens is disposed on an optical path of the reflected light between the first optical member and the first photoelectric conversion unit, and images the reflected light from the reading object on the first photoelectric conversion unit. The second carriage is movable in a main scanning direction orthogonal to the sub-scanning direction along the reading object with respect to the first carriage. The second carriage includes a second optical member for guiding the reflected light from the reading object, a second photoelectric conversion unit that receives the reflected light from the reading object guided through the second optical member to output an image signal, and a second lens that is disposed on an optical path of the reflected light between the second optical member and the second photoelectric conversion unit and images the reflected light from the reading object on the second photoelectric conversion unit at a magnification different from the first lens.

There is provided a scanner including: a first light source that generates light of a first wavelength; a mark that emits light in a case where light of the first wavelength is received; a deviation calculation section that calculates a deviation between a plurality of sensors based on sensor outputs acquired in such a way that the sensors detect light emitted from the same mark; a second light source that generates light which does not include light of the first wavelength; and an image generation section that generates image data based on the sensor outputs, acquired in such a way that the plurality of sensors detect light acquired when light from the second light source is stuck on and is reflected in the document, and the deviation.

The present disclosure discloses methods and systems to allow a user to select and send multiple scanned documents to multiple destinations in a single submission. The method includes receiving multiple scan jobs separated using a pre-defined separator at a multi-function device. Each scan job includes a document having one or more pages. The multiple scan jobs are scanned to generate multiple scanned documents, where each scanned document is generated corresponding to a single scan job. Then, each scanned document and corresponding multiple destinations are displayed to a user via a user interface for selection. Based on the user selection, each scanned document is sent to the multiple selected destinations in a single submission.

A device, a process execution system, a process execution method, and a non-transitory recording medium. The device requests an information processing system to perform a second process using result of a first process executed by the device, displays on a display, result of the second process acquired from the information processing system, and receives a request for the device to execute the first process again.

An image processing apparatus includes circuitry to receive visible image data obtained by reading of a subject with a sensor having sensitivity to visible light in a visible wavelength range and invisible image data obtained by reading of the subject with a sensor having sensitivity to invisible light in an invisible wavelength range. The circuitry generates image data for displaying, in a designated color, a portion of the visible image data corresponding to a designated region of the invisible image data. The designated region has an absorption rate equal to or higher than a predetermined absorption rate.

According to one embodiment, an image reading apparatus includes: a first illumination device for irradiating light at a first angle onto a sheet that is being conveyed; a second illumination device for irradiating light at a second angle onto the sheet that is being conveyed; illumination controllers for switching between a first irradiation state in which light is irradiated from the first illumination unit and the second illumination unit onto the sheet and a second irradiation state in which light is irradiated from only either the first illumination device or the second illumination device to the sheet; an imaging device for acquiring a first comparable image in the first irradiation state and for acquiring a second comparable image in the second irradiation state; and a defect detector for detecting a defect of the sheet based on the difference between the first comparable image and the second comparable image.

A read image processing apparatus is provided for processing a read image read by line image sensors arranged such that one end parts of which adjacent to each other are overlapped in a sub-scanning direction. The read image processing apparatus includes a density variation detector, a seam processor, and a line image generator. The density variation detector detects whether a density variation occurs for not less than a predetermined number of times or not in each of a plurality of regions in a seam-read image. The seam processor generates a seam image by synthesizing the seam-read images read by the line image sensors adjacent to each other in accordance with a detection result made by the density variation detector. The line image generator generates a read image corresponding to one line based on read images read by the line image sensors and the seam image generated by the seam processor.
