The present disclosure provides a scanning device, an image-forming apparatus, and a scanning method. In one aspect, the scanning device provided by the present disclosure includes a first sensor, a second sensor, a first channel corresponding to the first sensor, a second channel corresponding to the second sensor, and a selector. The first sensor is configured to collect first image data of a to-be-scanned document. The second sensor is configured to collect second image data of the to-be-scanned document. The selector is configured to acquire image data alternately from the first channel and the second channel to acquire a pixel of the first image data from the first channel and a pixel of the second image data from the second channel by using a pixel-by-pixel acquisition mode for each of the first and second channels in one acquisition cycle.

An image processing device includes an image data acquisition section configured to acquire image data of an image to be printed on a print medium; a parameter acquisition section configured to acquire parameters for performing physical based rendering of the print medium on which the image is to be printed as a 3D object, the parameters including a normal line map representing a normal line direction of an irregularities surface of the print medium related to a reflection direction of light incident on the print medium; a correction section configured to correct strength of an application effect of the normal line map corresponded with the 3D object; and a rendering execution section for generating a rendering image representing the print medium on which the image is printed by executing the physical based rendering using the image data and the parameters.

The present invention relates to a method and system for tracking, issuing, and authenticating gear or articles, such as uniforms, badges, equipment, weapons, etc, for use in law enforcement or other official capacity. An authentication system retrieves encoded information read by a reader from a plurality of different markers. A database is queried to retrieve biometric data corresponding to each marker whereby the biometric data is displayed on a display. A uniform having a computer-readable marker visible under ultraviolet light and an additional marker. A system for issuing one of the articles by authenticating an officer and storing the identity and encoded information in a database. An apparatus for applying a plurality of markers by way of a conveyor belt conveying the article by an ink jet printer and a laser engraver.

An image forming apparatus includes a reading unit, an image forming unit, and a controller. The reading unit is configured to acquire image data by reading an image on a first sheet. The image forming unit is configure to form an image from the image data on a second sheet using a first color material and a second color material. The controller is configured to perform text recognition on the image data, cause the image forming unit to form text from the image data on the second sheet using the second color material, and cause the image forming unit to form portions of the image data other than the text on the second sheet using the first color material.

In one example of the disclosure, a set of electronic document templates is accessed and instances of duplicated document content are identified. Display of a user notice for first duplicated document content is caused. Responsive to receipt of data indicative of a user instruction to create a component template for the first duplicated content, the component template is created and stored.

An image processing apparatus includes an image acquiring portion, a pair generating portion, first through third determination portions, and an image combining portion. The image acquiring portion acquires an image for each page of a booklet. The pair generating portion arranges the images in order of the pages of the booklet, and generates pairs from the arranged images, each pair being a pair of adjacent pages in a spread state of the booklet. The first determination portion determines whether a drawn image is present in a band-like region including a boundary between two images in each of the pairs. The second determination portion determines whether there is drawing continuity between the two images. The third determination portion determines whether the two images have to be combined, on the basis of determination results of the first and second determination portions. If so, the image combining portion combines the two images.

An image data creating device includes a converter that converts first image data defined by an input signal value to second image data defined by an output signal value of a CMYK color space, and a changer that changes, in forming a mixed color represented by mixing at least two of a cyan ink, a magenta ink, a yellow ink, and a black ink, based on the second image data, the second image data such that at least a portion of the cyan ink, the magenta ink, the yellow ink, and the black ink is replaced with a first special color ink that has a first special color that is a color other than cyan, magenta, yellow, and black.

A printing apparatus having a copying function includes a document feeder that feeds a document, an image reading section that scans the document fed from the document feeder and generates image data of the document, a printing section that performs printing on paper in accordance with the image data, and a controller. The controller performs an avoidance process of avoiding performing the printing in which a size of a sheet of the document and a size of the paper do not match against an intention of a user, in a case where a setting is made in which the document, on which single-sided printing is performed, is printed on both sides of the paper to perform double-sided printing, and the document includes sheets having different sizes and includes an odd number of successive sheets with an identical size.

An inkjet printer includes an inkjet head having a first nozzle for ejecting first ink supplied from a first tank and a second nozzle for ejecting second ink supplied from a second tank, and a controller. The controller determine whether a replenishment condition is satisfied. When print data instructing to print with the first ink is received, in a case of determining that the replenishment condition is not satisfied, the controller causes the inkjet head to perform a first ejecting operation of ejecting ink from the first nozzle toward a medium and prohibiting ejection of ink from the second nozzle. When print data instructing to print with the first ink is received, in a case of determining that the replenishment condition is satisfied, the controller causes the inkjet head to perform a second ejecting operation of ejecting ink from at least the second nozzle toward a medium.

An image forming apparatus includes an image forming unit configured to perform a printing process of forming an image on a print medium based on print data, and a processor. The processor is configured to determine whether or not the printing process has completed based on remaining print data to be printed, when the print medium is removed from a paper discharge tray in which the print medium on which the image is formed by the image forming unit is placed, and to cause a warning to be output upon determining that the printing process has not completed based on the remaining print data to be printed.
