A method is disclosed. For example, the method executed by a processor of a multi-function device (MFD) includes executing a defect learning routine to identify defects, cataloging the defects based on a job function, a type of paper, and a machine state, receiving a job request, determining a known defect that has been catalogued based on the job function, the type of paper, and the machine state, and presenting a visualization of the known defect on a display of a user interface before executing the job request.

In one aspect, an LED display includes a matrix of LED pixels for producing a demanded image, and within the matrix, one or more sensor elements to detect visible light for document scanning, and/or IR light, and/or laser light. IR emitters also can be part of the matrix for time-of-flight based distance measurements using the matrix. The matrix background can be black or it can be e-ink to present, e.g., interactive user controls.

An image forming apparatus includes a conveyance part, an image forming part, a sheet detection sensor, a sensor unit, and a controller. The sheet detection sensor, in which a plurality of sensor blocks each with a plurality of sensor elements mounted thereon at specified intervals are arrayed in a sheet width direction, detects an edge position in the sheet width direction on a basis of scanning image data formed by reading of the sheet. The controller is enabled to execute a calibration of inserting, into the scanning image data, interpolation pixels for compensating an error between an edge position detected by the scanning image data and an actual edge position.

A radiation imaging apparatus includes a pixel array including n pixel rows, where n≥3, and a driving circuit configured to scan the pixel array from a first row toward an n.sup.th row, counting from one end of the pixel array. In a case where a region of interest is included in a partial region composed of pixel rows from an i.sup.th row to a j.sup.th row, where 1<i≤j<n, the driving circuit starts scanning of the pixel array from the first row, and starts scanning of the pixel array from the first row again during scanning of pixel rows from a (j+1).sup.th row to the n.sup.th row.

An example scanner assembly includes a housing formed with corners to allow an image sensor line to align cornerwise. An example scanner apparatus may include a plurality of scanner assemblies with an image sensor line oblique to the media advance direction.

An image data generation apparatus includes circuitry configured to refer to image processing association information in which a plurality of image defect types is associated with a plurality of different image processing, respectively; apply, to image data, image processing selected from the plurality of different image processing in accordance with an image defect type included in the image data; and generate processed image data from the image data.

An optical-scanning observation device includes: a light source unit outputting illumination light; a light scanning unit scanning the illumination light; a light detection unit detecting signal light produced at each scan position and generating and outputting a light detection signal based on intensity of the signal light; a power supply unit supplying power to the light detection unit; a determination unit determining, every time the light detection signal is output, whether the intensity of the signal light is equal to or greater than a threshold set on the basis of a current capacity of the power supply unit; and an image generating unit generating an image having a pixel value based on the intensity of the signal light. The image generating unit generates an image having a saturated pixel value in a region determined that the intensity of the signal light is equal to or greater than the threshold.

The present disclosure pertains to an image reading device that may include an image reader, an operation detector, a correction parameter adjuster, an entry detector, and a document reading controller. The image reader may read an image on a document. The operation detector may detect an operation indicating a start of a reading of the image on the document. The correction parameter adjuster may perform adjustment of a correction parameter. The entry detector may detect entry of a document reading instruction including a reading condition. The document reading controller may check for completion of the adjustment of the correction parameter for the reading condition. If the adjustment of the correction parameter is not completed, the document reading controller may instruct the correction parameter adjuster to perform adjustment of an uncompleted correction parameter and instruct the image reader to read the image.
