Provided is an image processing apparatus for extracting embedded information from a printed document printed by an electrophotographic method, including: a first obtaining unit configured to obtain first image data by reading the printed document while applying light to the printed document; a second obtaining unit configured to obtain second image data by reading the printed document without applying light to the printed document; a determination unit configured to determine whether a high color density region of which density is higher than a predetermined value is present in the printed document; and a decision unit configured to decide which of the first image data and the second image data to set as image data to be used to extract the embedded information, according to the determination made by the determination unit.

In a scanning system including a web application cooperating with a message sharing system and an image processing apparatus provided with a scanner, the web application holds card information acquired from a scanning request source and a destination of scan data in association with each other in response to a scanning request from a user account belonging to the message sharing system. An image processing apparatus transmits the scan data generated based on scanning and the card information that has been read to the web application. The web application specifies a destination associated with the card information that has been received from the image processing apparatus and posts the scan data that have been transmitted from the image processor to the message sharing system.

Some embodiments are directed to an image processing apparatus comprising obtaining a reference image and a verification target image; selecting one or more defect detection processing from a plurality of types of defect detection processing for performing defect detection in the verification target image; executing the selected one or more defect detection processing on a difference image between the reference image and the verification target image in accordance with processing parameters of the selected one or more defect detection processing; and outputting a result display screen in which a defect in the verification target image and a defect detection processing used for detecting the defect can be identified, in a case where the defect is detected.

An image reading apparatus includes a conveyor configured to convey an original in a conveyance direction; a reader configured to read an image of the original conveyed by the conveyor; and at least one processor configured to: determine, based on the image read by the reader, an inclination amount corresponding to an inclination angle of a side of a leading edge of the original in the conveyance direction, wherein the inclination angle represents an inclination of the side of the leading edge of the original with respect to a width direction orthogonal to the conveyance direction; rotationally correct the image read by the reader by the inclination amount so as to reduce the inclination amount to output a first image in which the rotationally corrected image is included in a case where the inclination amount is smaller than a predetermined amount.

An image reading apparatus includes a control unit configured to detect occurrence or non-occurrence of multi-sheet feed of a medium based on a reception level signal output by a reception unit in accordance with the received ultrasonic wave. The control unit, after a tip of the medium reaches the positions of the reception unit in a transport path, when the reception level signal is below a predetermined threshold, causes the driving voltage to rise, when an amount of change in the reception level signal in accordance with the rise in the driving voltage is smaller than a reference amount of change, determines that multi-sheet feed is ongoing, and when the amount of change in the reception level signal in accordance with the rise in the driving voltage is greater than the reference amount of change, determines that multi-sheet feed is not ongoing.

A reading apparatus includes a first roller pair, a second roller pair provided downstream of the first roller pair, a light transmitting member, a reading portion and an opposing member. The transmitting member is disposed between the first and second roller pairs in a sheet feeding direction and on a first side in a vertical direction with respect to a nip line of the first roller pair. The opposing member is disposed on a second side opposite to the first side with respect to the transmitting member. As seen in a sheet widthwise direction, a surface of the second side of the transmitting member in the vertical direction is inclined, with respect to the nip line, to the second side toward downstream of the sheet feeding direction.

When a medium detector detects that a state where a medium is absent is switched to a state where the medium is present with a light quantity of the medium detector set to a first light quantity, a controller in an image reading apparatus switches the light quantity from the first light quantity to a second light quantity, which is larger than the first light quantity. When a quantity of the light received by the medium detector exceeds a threshold, the controller determines whether the media overlaps each other, based on the detection result of the multi-feed detector. When the quantity of the light received does not exceed the threshold, the controller skips the determination of whether the media overlaps each other.

A reading apparatus comprising a lower case, a reading portion, a drive portion and a stay is used. The reading portion moves between an open position in which the lower case is open and a closed position in which the lower case is closed and accommodates a reading sensor. The drive portion moves the reading sensor in a moving direction. The stay is coupled to the reading portion rotatably in one end and coupled to the lower case rotatably in the other end and moves a rotation shaft with in a direction orthogonal to the shaft. The drive portion is located outside a movable range of the reading sensor. When the reading portion is in the closed position, the stay is disposed in an area in which the stay overlaps the drive portion in the moving direction and overlaps the drive portion in height direction.
