A reading device includes a position reference member and a reader. The position reference member has a reference pattern that includes a line extending in a prescribed direction. The position reference member is configured to relatively move in a direction orthogonal to the prescribed direction. The reader includes a plurality of sensor chips, each of the sensor chips including a plurality of pixels. The reference pattern corresponds to each of the sensor chips of the reader.

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.

A device for digitizing papers, including a controller having a processor and memory, a digitizing scanner configured to accept a paper, digitize content of the paper and transfer the digitized content to the controller, a program executed by the controller that is configured to identify calibration markings or unique fingerprints from specific locations of the paper, embedded in the digitized content, wherein the program provides a determination that the digitizing scanner is functioning correctly if the calibration markings or unique fingerprint are identified as being correct or by identifying a type of paper digitized from characteristics of the unique fingerprint.

An image recording device includes a recorder, a reader and a hardware processor. The recorder records an image on a recording medium. The reader reads, with an imaging element, a surface of the recording medium and a surface of a predetermined reference member. The hardware processor calibrates the reader for a value to be detected by the imaging element, based on a reading result of the reading of the surface of the reference member. Further, the hardware processor performs the calibration in at least one of: a case where a type of the image to be recorded on the recording medium satisfies a predetermined image type condition; and a case where a predetermined reading influence factor which affects a reading result of the reading of the surface of the recording medium satisfies a predetermined reading influence factor condition.

According to an example, a scanner apparatus may include a housing, a scan panel positioned on the housing and a lid rotatably mounted to the housing. The lid may be moved between a closed position and an open position, in which in the closed position, the lid covers the scan panel and in the open position, the lid is extended away from the scan panel. The scanner apparatus may also include an optical sensor to detect media placed on the scan panel and a media engine to determine whether the optical sensor has detected a media on the scan panel while the lid is in the open position.

Disclosed is an image reading device including: a reader that reads an image on a continuous sheet; a conveying member that conveys the continuous sheet to a reading position; a calibration member that is movable to the reading position; a hardware processor that moves the conveying member and the calibration member so as to switch an arrangement between a first arrangement in which the continuous sheet directly faces the reader and a second arrangement in which the continuous sheet is located away from the reader and the calibration member directly faces the reader; and a pressing member that is disposed at the side of the reader parallel to a reading surface and that applies tension to the continuous sheet in the first arrangement so as to position a sheet surface of the continuous sheet at the reading surface.

An encoding apparatus includes circuitry. The circuitry is configured to read predetermined unit image data that is a predetermined plurality of pixel units of image data; generate pixel unit code data obtained by encoding the read predetermined unit image data on a pixel basis; generate predetermined unit code data obtained by encoding the read predetermined unit image data on a predetermined unit basis; compare a code length that is a data amount of the pixel unit code data with a data amount of the predetermined unit image data to make determination; and output the predetermined unit code data in a case where the code length is greater than the data amount of the predetermined unit image data and output the pixel unit code data in a case where the code length is not greater than the data amount, on basis of a result of the determination.

There is herein described a method and apparatus for the calibration and validation of motion picture scans.

A copying apparatus capable of calibrating a copy position comprises a scanning module scanning an original to obtain an original image; and a processing module being electrically connected to the scanning module and recognizing whether the original image contains an original mark corresponding to a template mark. If the original image contains the original mark, then the processing module generates print data for being printed out according to the original image and a position parameter of the template mark. A copying method capable of calibrating the copy position is also provided. Thus, the copy position can be calibrated according to the mark of the original to prevent the copy result from having a positional offset. Consequently, no positional offset occurs even if the original is copied multiple times based on the previous generation of original.

An image reading apparatus comprises a light source for repeatedly emitting first light having a first color, second light having a second color and third light having a third color toward a read target while moving the light source in a sub-scanning direction, first, second, and third sensors, each configured to sense a strength of first, second, and third reflected light, respectively, in a light reflected from the read target, and to output first, second, and third signal waveforms corresponding to the strength of the first, second, and third reflected light, respectively, and a controller. The controller is configured to execute a line-to-line correction for correcting a phase shift between the first, second, and third signal waveforms, and to correct a shift in a signal level caused by the line-to-line correction.
