Reading device to read and output an invisible image included in a document
A reading device includes a light source, an imaging element, a controller, a correcting unit, and a notifying unit. The light source is configured to irradiate an object with light. The imaging element is configured to receive and read the light from the object. The controller is configured to control a second reading operation of reading the object with an invisible image. The correcting unit is configured to perform correction with respect to the invisible image. The notifying unit is configured to notify an outside of at least the invisible image corrected.
Reading device, image forming apparatus, correction value calculating method, and storage medium storing program code
A reading device including a position reference member having a reference pattern having a line extending along a first direction of the position reference member, the position reference member movable in a second direction orthogonal to the first direction; a reader including a plurality of sensor chips arranged along the first direction, each of the sensor chips having a length defined by a plurality of pixels; and circuitry. The circuitry is configured to detect the reference pattern of the position reference member using the reader; determine coordinates of at least two sensor chips in the second direction, based on the detected reference pattern of the position reference member; and correct a position of a reading target in the second direction based on the coordinates determined for the at least two sensor chips of the reader in the second direction.
SYSTEM FOR SELECTIVE EVENT-BASED DOCUMENT SCANNING AND CAPTURED IMAGE STORAGE
A system for selective document scanning and storage is provided. The system comprises: a memory device with computer-readable program code stored thereon; a communication device connected to a network; and a processing device, wherein the processing device is configured to execute the computer-readable program code to: receive a document via a user device comprising an image capturing device configured to capture an image of the document; determine an error with the document; in response to determining the error with the document, trigger transmission of a signal to the image capture device; and modify a document image capture based on receiving the signal at the image capture device.
PRINTING PRODUCTION QUALITY PREDICTION
A system and method for providing three dimensional printing production quality prediction is described herein. The system may include logic to scan a region of interest associated with a layer of a plurality of parts during printing to obtain an input for the region of interest and compute an input metric associated with the layer based on the input. In response to an initial set of print jobs, at least a portion of the plurality of parts is mechanically tested to determine at least one output. In response to a production print job, a likelihood of a part of the plurality of parts to satisfy a quality specification is predicted by inputting the input metric to at least one machine learning function comprising the at least one output, wherein the at least one machine learning function is trained during the initial set of print jobs.
Digital image-paper registration error correction through image shear
A method, non-transitory computer readable medium and apparatus for applying an image shear to correct a digital image-paper registration error are disclosed. For example, the method, performed by a processor of a printing device, includes detecting an amount of skew of a paper traveling through a registration system of a printing device, determining that the amount of skew is greater than a predefined threshold, applying an image shear to a digital image that will be printed on the paper, and controlling a plurality of printheads of the printing device to print the digital image on the paper with the image shear that is applied.
IMAGE PROCESSING METHOD, IMAGE PROCESSING APPARATUS, AND IMAGE PROCESSING PROGRAM
An image processing method in a system capable of forming a second image with a second color material on a sheet while forming, as a base, a first image with a first color material on the basis of print data, the method includes: acquiring color information regarding the sheet, the first image, and the second image; and enlarging or reducing an area of the second image protruding from the first image on the basis of the color information regarding the sheet, the first image, and the second image.
Image reading apparatus and dirt detection method
An image reading apparatus includes a reading section that receives light input via a transparent member to perform reading, a background section configured to switch a background facing the transparent member either to a first background that is a background of a first color or to a second background that is a background of a second color brighter than the first color, and a control section. The control section compares, with a threshold set in advance, first read data generated by causing the reading section to perform reading of the first background, compares, with the threshold, second read data generated by causing the reading section to perform reading of the second background, and, when the first read data is above the threshold or when the second read data is below the threshold, determines that dirt is present on the transparent member.
Medium transport apparatus and image reading apparatus
A detection section that detects a value used for determining whether or not a jam of a paper sheet has occurred includes a sound detection unit that detects a sound and an auxiliary detection unit that detects a value different from the magnitude of a sound in the case where a jam of the paper sheet has occurred, and, in the case where the sound detection unit has detected a sound of a magnitude equal to or greater than a first threshold value, a control unit controls determines whether or not a jam of the paper sheet has occurred with reference to a detection result of the auxiliary detection unit, and controls a transport unit on the basis of a result of the determination.
IMAGE INSPECTION APPARATUS, IMAGE INSPECTION METHOD, AND IMAGE INSPECTION PROGRAM
An image inspection apparatus includes: a central processing unit (CPU) that inspects an image obtained by reading a printing paper after image formation in which an original image is laid out on the printing paper and an image is formed by an image forming apparatus, obtain a printing area of the original image on the printing paper, designates an inspection exclusion area on the printing paper, and in response to a change in the printing area of the original image on the printing paper, changes the inspection exclusion area on the printing paper based on the change in the printing area.
Image processing device, image reading apparatus, image processing method
In an image processing device, a sampling portion selects, as a target line, each of four reference lines that pass through a pixel of interest in a 33 target pixel group. When a difference between data among a pair of neighboring pixels, positioned along the target line, is within a predetermined first selection reference range, and with respect to at least one of two areas on both sides of the target line, all differences among data of three neighboring pixels that exist in the area are within a predetermined second selection reference range, the sampling portion selects the pair of neighboring pixels as the sample pixels. When a difference between data of the pixel of interest and an average value of the sample pixels exceeds a predetermined correction reference range, the device corrects the data of the pixel of interest to a value based on the sample average value.
