An image processing apparatus includes first and second detecting units, a conveying unit, a reading unit, a setting unit, an executing unit, a storing unit, and a correcting unit. The first detecting unit detects a size of a set document. The conveying unit conveys the set document. The second detecting unit detects a size of the conveyed document. The reading unit reads an image of the conveyed document and generates image data. The setting unit sets a setting value based on the detected size before the document image is read. The executing unit executes image processing on the image data, based on the set setting value. The storing unit stores the image data. The correcting unit corrects, where the size detected by the second detecting does not match the size detected by the first detecting, the stored image data based on the size detected by the second detecting unit.

A document contains a security element that combines a correlation mark and pantograph mark. The pantograph mark includes a dot pattern, part of which is printed to correspond to foreground pixels of the correlation mark, and another part of which is printed to correspond to background pixels of the correlation mark.

An image processing apparatus is communicable with a system including a censorship function, and includes one or more controllers having one or more processors and one or more memories, and the one or more controllers are configured to transmit an image acquired by reading a display medium to the system, receive a censorship result from the system, and control the image processing apparatus to perform a predetermined operation corresponding to the received censorship result, wherein the predetermined operation is a preset operation to be performed by the image processing apparatus based on the received censorship result.

Example implementations relate to hiding sensitive data. For example, a device according to the present disclosure may include a scanning portion to receive a scan of a document, and a graphical user interface to receive a command with respect to the sensitive data. The device may also include a processor to analyze the scan of the document, process the command via the graphical user interface, determine the document contains sensitive data in response to the command, and perform an action to hide the sensitive data.

A visual privacy system unilaterally blocks rolling shutter cameras by providing a periodically interrupted ambient light source imposing bright and dark bands on the image yet at a frequency imperceptible to human observers in the environment. Communication of the modulation pattern to authorized cameras allows unaffected imaging in these regions by authorized individuals. The system also contemplates operation in a barcoding mode with a light modulation providing embedded barcodes that can be extracted from images taken in the region to indicate that the images were improperly acquired and to block the images in certain applications.

The invention provides methods and apparatus for securing personalized or sensitive information appearing in digital images. Digital images containing information to be secured is processed and divided into a plurality of image cells. At least one image cell from the plurality of image cells is selected and redacted or altered to render the information to be secured with the selected image cells in decipherable. The invention also provide method and apparatus for transmitting or streaming unredacted image cells alone or in combination with redacted image cell for secured viewing on a user browser or computer.

An image forming apparatus includes an image forming unit, a first reader/writer device, a second reader/writer device, and a control unit. The first reader/writer device executes a wireless read/write operation on a wireless tag and is positioned in a sheet conveying path upstream of the image forming unit. The second reader/writer device executes a wireless read/write operation on a wireless tag and is positioned in the sheet conveying path downstream of the image forming unit. The control unit controls the image forming unit, the first reader/writer device, and the second reader/writer device. The control unit controls the second reader/writer device to perform an operation to detect a defect in a wireless tag that is included in a sheet as the sheet is conveyed along the sheet conveying path past the location of the second reader/writer device.

The invention provides methods and apparatus for securing personalized or sensitive information appearing in digital images. Digital images containing information to be secured is processed and divided into a plurality of image cells. At least one image cell from the plurality of image cells is selected and redacted or altered to render the information to be secured with the selected image cells indecipherable. The invention also provides methods and apparatus for transmitting or streaming unredacted image cells alone or in combination with redacted image cells for secured viewing on a user browser or computer.

An image processing device includes an association unit, a generation unit, an output unit, a reception unit, and a print unit. The association unit associates a first document image with a second image, the second image being an image of a reverse side of the first document image. The generation unit generates multiple images in accordance with a result of the association. The output unit outputs the multiple images generated by the generation unit. The reception unit receives a selection of an image output by the output unit, the selection being made by a user operation. The print unit prints the selected image.

The invention provides methods and apparatus for securing personalized or sensitive information appearing in digital images. Digital images containing information to be secured is processed and divided into a plurality of image cells. At least one image cell from the plurality of image cells is selected and redacted or altered to render the information to be secured with the selected image cells indecipherable.
