Abstract:
A computer-implemented method of operating a server computer serving a group of scanners connected to the server via a data network; wherein the scanners are registered in a database with a respective indication of reservation status. The method comprises receiving, at the server computer, a request for a scanning operation from a user's electronic device; wherein the request comprises a user identifier and a scanner identifier selecting a scanner as a selected scanner from among the group of scanners; granting a reservation of the selected scanner upon reception of the request for a scanning operation, comprising altering the reservation status in the database; wherein the reservation lapses unless the request is confirmed within a predefined time period; and receiving, from the selected scanner, a predefined user generated event. Upon reception of the predefined user generated event within the predefined time period: maintaining the reservation until a scanning operation is terminated or cancelled, and transmitting any electronic reproduction resulting from the selected scanning operation performed at the selected scanner to the user identified by the user identifier. Consequently, the electronic reproduction is delivered to the right user.
Abstract:
A method for detecting printing defects includes, with a physical computing system (100), creating a matched reference image (500) from a digital image (300), colors of said matched reference image (500) being closer matched to a scanned image (302) of said digital image (300). The method further includes, with said physical computing system (100), determining a color difference between corresponding points on said matched reference image (500) and said scanned image (302); and with said physical computing system (100), identifying points that have said color distance greater than a predefined threshold as potential defects.
Abstract:
A system and method for automatically determine whether an image captured by a digital camera should be stored in a raw format or a compressed format. After an image is captured by the digital camera, the digital camera checks certain sets of characteristics of the captured image to check the image quality. If the image quality falls within an acceptable range, then the digital camera saves the image in a compressed format. If the captured image does not fall within predetermined quality levels, then the captured image is save in raw format for later processing.
Abstract:
A dynamic image adaptation system and method for adjusting the quality of digital prints.The system includes an illumination source that illuminates an imaging surface of a live scanner optical system, the live scanner optical system scanning a biometric object placed on the imaging surface, a camera for capturing the print image of the biometric object placed on the imaging surface, a memory that stores data generated in the system, and a controller that adaptively controls at least one of the illumination source or the camera to obtain the print image with the predetermined quality. The controller adaptively controls the camera and the illumination source by adjusting one or more of contrast, gain, and integration time for the camera, and illumination for the illumination source.
Abstract:
Le procédé selon l'invention consiste à faire défiler le film (1) dans un montage optique comprenant, d'un côté du film, au moins deux sources de lumière (3a, 3b), de longueurs d'onde différentes qui éclairent le film dans une zone de faible largeur, et, de l'autre côté du film, un objectif (7) qui projette les deux images de la zone éclairée par les faisceaux (4a, 4b) émanant des deux sources, sur deux éléments linéaires photosensibles respectivement adaptés aux longueurs d'onde des deux sources, et à comparer les données numériques délivrées par les deux éléments de détection, le résultat de cette comparaison servant à effectuer la susdite détection et la susdite correction. Elle s'applique à la détection de défauts tels que souillures, rayures, poussières sur un film.
Abstract:
A printer (300) is disclosed. The printer has two scanners (336, 338) in the paper path of the printer located after the print zone (346). The two scanners are spaced appart from each other by a known distance A and overlap each other in a direction perpendicular to the media axis of travel. The two scanners capture a first and second image of the media.
Abstract:
When a user sets, through an operation unit, an inspection item of inspection processing which inspects a print state by reading image data by the image reading unit from a sheet output from a printer unit and conveyed by conveyance rollers, an inspection control unit of an inspection unit changes a sheet conveyance speed in the inspection unit and sheet feeding timing according to the inspection item. A print medium conveyance control unit controls drive of conveyance rollers according to the sheet conveyance speed and the sheet feeding timing.
Abstract:
A document scanner with automatic dust avoidance includes an automated document feeder; a transparent plate; an illumination source for illuminating the document through the transparent plate; at least one mirror for reflecting light reflected from the document; at least one sensor for imaging light from the at least one mirror; a microprocessor for determining the presence of dust on the transparent plate; and a motor for tilting the at least one mirror when dust is detected on the transparent plate.
