The invention relates to a method for scanning originals using a scanner, for example a flatbed scanner, said method comprising the steps of: (i) performing a pre-scan using a scanner bed (2) of the scanner, said scanner bed (2) having an extension in the x-direction and in the y-direction, in order to measure an x-extension (4) between a smallest (4a) and a largest extension value (4b) in the x-direction and to measure a y-extension (6) between a smallest (6a) and a largest extension value (6b) in the y-direction in respect of each of the originals on the scanner bed (2), and creating scanning frames (R1, R2, R3, R4, R5, R6) associated with the originals from the respectively measured extension values, (ii) specifying the scanning frame (R1, R2, R3, R4, R5, R6) with the largest y-extension (6) as the leading frame (R4), (iii) defining as subsequent frames (R3, R5) those which are located with their y-extension within a section (10) of the scanning bed which is spanned in the y-direction by the smallest and the largest extension value of the y-extension of the leading frame, (iv) creating an image processing dataset from said section, its leading frame and its subsequent frames, (v) registering said image processing dataset in a list of image processing datasets, (vi) performing steps (ii) to (v), without taking into account the scanning frames already existing in an image processing dataset, until all the scanning frames measured in step (i) are included in an image processing dataset, (vii) capturing image data by scanning the sections of the image processing datasets registered in the list, (viii) cropping the image data of originals from the captured image data along the scanning frame, and (ix) storing the cropped image data of the originals.

An image reading apparatus includes an image sensor to read a document, a sensor to detect whether the document is loaded on the image reading apparatus, and a processor to, when the sensor detects the document is loaded on the image reading apparatus, and before a scan instruction is input to the image reading apparatus, control the image sensor to execute a pre-scan job with respect to the loaded document using a default set value.

A system and method for aligning documents for scanning includes a multifunction peripheral with a controller having a processor and associated memory. The controller issues instructions controlling operation of a scanner. A tangible document is placed on a surface of a scanner platen, and a sensor determines its location relative to the platen. An optimal position of the document relative to the platen is determined. The processor then generates a graphical rendering on an associated display indicative of a directed repositioning of the document on the platen in accordance with a determined optimal position of the document relative to the platen.

Provided is an image reading apparatus in which a setting screen is displayed upon detecting that a document is placed on the document tray. In a case where a document is placed on an automatic document conveyance device, if a paper jam occurs while using the automatic document conveyance device, a screen of a paper jam is preferentially displayed even when a setting of automatically displaying a selection screen of a sheet thickness is set at the time. This prevents a specific screen desired to be continuously displayed from being hidden upon detecting that a document is placed on a document tray.

A scanning system includes: a configurator configured to make a first setting corresponding to an image captured by a pre-scan the setting of a process accompanying scanning based on learning results acquired by machine learning using training data related to a setting of the process accompanying scanning that is applied to a scanned image; and an executor that executes the process accompanying scanning based on the first setting.

A system and method for automatically changing the operation of a mobile device in response to a presence of information is described. In some examples, the system determines an information capture device is proximate to text, automatically changes operation of the capture device to a certain mode, captures the text, and performs an action associated with the captured text.

A background image is acquired by imaging an opening plate as a background of an original document in a state where the original document is not arranged. Next, an original document including background image is acquired by imaging the same range as the background image in a state where the original document is arranged on an upper surface of the opening plate. Next, a difference image is generated by subtracting the background image from the original document including background image. In addition, an inverse difference image is generated by subtracting the original document including background image from the background image. A region of the original document is detected based on the difference image and the inverse difference image.

An image reading apparatus comprising: an original reading unit configured to read an image of each of multiple originals placed on an original table in batch by a batch-scan; a cropping unit configured to crop an image of each original from an entire image which is read by the batch-scan; an image output unit configured to output a cropped image of each original; and a control unit configured to control the original reading unit, the cropping unit, and the image output unit, wherein the control unit makes the original reading unit read the image by a batch-scan in which an image density of an edge of each original is supposed to be higher than an image density of a reading-area outside of the original, and an area to be cropped is determined on the basis of a difference in the image density between the edge and the reading-area outside of the original.

A background image is acquired by imaging an opening plate as a background of an original document in a state where the original document is not arranged. Next, an original document including background image is acquired by imaging the same range as the background image in a state where the original document is arranged on an upper surface of the opening plate. Next, a difference image is generated by subtracting the background image from the original document including background image. In addition, an inverse difference image is generated by subtracting the original document including background image from the background image. A region of the original document is detected based on the difference image and the inverse difference image.
