Abstract:
An image reading apparatus (9, 10) capable of shortening the reading processing time in image reading of high definition. In an image reading apparatus having a plurality of reading definition values, the state of a reading subject (13) is monitored with first definition. On the basis of a result of the monitoring, image reading (25) is conducted with second definition higher in definition than the first definition. A function (23, 35) of giving a stillness determination on an image of low definition is added. Switchover of the image to the high definition and read processing start are automatically carried out.
Abstract:
PURPOSE: To provide an image reader, in which the read processing time is shortened at the time of reading a picture of high definition. CONSTITUTION: In the image reader having a plurality of read definitions, monitor processing of the state of a read object is performed at first definition level, and image reading is performed with a second definition of higher definition than the first definition, on the basis of the monitor processing result. A function for discriminating static state of an image with low definition is added to automatically perform image switching to a high definition and the start of read processing.
Abstract:
The Input system has the contiunous marks on a medium having an image or images such as characters or graphic patterns being read by the scanner. The data processor including a microcomputer reads the image and the mark scanned, and the microcomputer eliminates overlapping of the pieces of image data in accordance with the data representing the mark.
Abstract:
An optical scanning system and method for laser engraving a plurality of data sut rasters into a substrate to form a raster of engraved data defining an image on the substrate. Each subraster has a length dimension and a width dimension. The system includes a transport assembly having an objective lens and a mirror, the mirror capable of refl(;cting a substantially collimated scanning beam incident thereon in a direction transverse to a l axis of the incident beam such that it is directed to the objective lens. The objective lens is capable of focusing the scanning beam on the substrate to engrave a set of data in the width dimension of the subraster and the objective lens and mirror combination is capable of moving along the axis of the incident beam to allow subsequent engraving of other sets of data in the width dimension until a complete subraster is formed along its length dimension. The objective lens and mirror combination is also capable of returning to its starting position to begin engraving of a subsequent subraster of the plurality of subrasters forming the raster of engraved data. A thermoset plastic substrate is also identified as being particularly suitable for use with the aforementioned system and method.
Abstract:
Image scanning apparatus and method for scanning a capture image uses sensor means comprising an NxM array of image sensors for sensing a subset of said capture image; transport means for moving said capture image relative to said sensor means; and control means for co-ordinating said sensor means with said transport means; whereby said control means can provide a digital representation of said capture image.
Abstract:
A method for transmission of a sequence of high quality images for display on a visual display unit is described. It has particular application in the field of telepathology, where magnified images obtained by scanning a medical specimen on the stage of an optical microscope are transmitted from a local pathologist to a remote consultant for diagnosis. The method consists of the steps of advancing the field of view of the camera in discrete steps across the object being viewed to capture a sequence of contiguous images, temporarily storing a digital representation of a first of the images in a first buffer store and a digital representation of at least part of the next succeeding image in a second buffer store, controlling the data in the two buffer stores such that the data follows the leading edge of the advancing viewport and data in the first store representing a trailing incremental strip of the first stored image is progressively discarded while data in the second store representing a trailing incremental strip of the next contiguous image is transferred to a location in the first store occupied by the data representing leading incremental strip of the first stored image, and reading out the contents of the first buffer store to the display unit.
Abstract:
Une approche nouvelle et révolutionnaire du traitement d'images permet d'éliminer les limitations actuelles de la technologie vidéo pour ce qui est de l'analyse et du traitement des images vidéo. Un nouveau système de traitement de données "à grand format" permet à l'usager du système de traiter des données analogiques avec n'importe quel degré souhaité de définition. Le degré de définition pouvant être obtenu n'est limité que par les données de base et d'application avec lesquelles le système est utilisé. Le mode préférentiel de réalisation permet de segmenter la source de données analogiques (180), une carte, une photographie, une radiographie, ou n'importe quel objet bidimensionnel ou tridimensionnel pouvant être montré sur un système vidéo, en une série d'images vidéo qui produisent, lorsqu'elles sont traitées en séquence, une mosaïque précise de l'image originale. De cette façon il est possible de visionner, de mesurer ou d'esquisser les dimensions, la forme ou l'image d'un rocher, d'un arbre ou d'un étang sur une photographie d'un champ mesurant un acre, dans n'importe quel but souhaité par l'utilisateur du système. Les éléments fondamentaux du système sont une table de positionnement à coordonnées XY (31, 32, 34, 36, 40), un microordinateur (90), une caméra vidéo (10) pour saisir les images segmentées, et un poste ordinaire de télévision (100) pour afficher et analyser les images segmentées qui forment l'ensemble de l'enregistrement analogique de l'image originale (180). Les applications possibles du système sont pratiquement illimitées dans les domaines de l'agriculture, de l'agronomie, de l'élevage, de la fabrication, du contrôle de qualité, de la météréologie, de la médecine, et dans d'autres domaines similaires, et les formes possibles d'analyse sont également illimitées, étant donné que le système peut être utilisé dans l'analyse d'une surface, de mesures de distance, de caractéristiques thermiques ou de densité, ou de n'importre quel objet pouvant être mis électromagnétiquement en images.
Abstract:
This invention provides an image forming apparatus (100) capable of reliably printing security information even when image data of an original document that is obtained by a reading unit (113) contains security information and an area where the security information is not contained is set as a print area, and a control method thereof. To accomplish this, when image data of an original document contains security information, the image forming apparatus (100) extracts image the security information from data, and sets a print target area from an area indicated by the image data of the original document. When an area corresponding to, from which the security information is extracted, is not contained in the set print target area, the image forming apparatus (100) executes printing (114) using the extracted image data corresponding to the security information, and the image data corresponding to the print target area.
