Metadata values are extracted from each scanned document using metadata labels, and each scanned document is identified by using extracted metadata values. A stored electronic record is associated with each scanned document by employing the extracted metadata values such that a relationship between the stored electronic record and the associated scanned document is determined and stored. | 03-12-2009 |
20090091807 | Image-Capturing Apparatus - Image-capturing apparatus meeting demands for high-image resolution and high-speed data capture during both still- and moving-document data-capture modes. Includes: a reading unit having first and second linear photoreceptors arrayed along an data capture sub-scanning direction, a delay circuit delaying output from the first photoreceptor, and an adding circuit adding delayed first-photoreceptor output to second-photoreceptor output; and a scanning unit illuminating from underneath the platen, and shiftable along it to guide linear reflected light from a document to the first and second photoreceptors. During a moving-document data-capture mode, the scanning unit is disposed in a data-capture position established at one edge of the platen to scan a document being conveyed, and when in a still-original data-capture mode, it is shifted from along the platen's opposite edge toward the one edge thereof to scan a stationary document. | 04-09-2009 |
20100284048 | Techniques for obtaining scanning images and scanning device for the same - Techniques for scanning an object that does not fit upon a scan surface of a scanner and requires a non-linear scanning path are described. In one embodiment, a pair of optical navigation sensors and an image sensor (e.g., CIS) are used to determine coordinates and an angle of a scanning object. By acquiring the coordinates of optical navigation sensors with respect to the image sensor after each relative movement between the image sensor and the scanning object, coordinates of pixel points on the image sensor can be readily determined as long as there is a predefined geometry between the optical navigation sensors and the image sensor. In addition, scanned image data can be modified, enhanced or corrected in scanning or in memory. | 11-11-2010 |
20110085215 | IMAGE-CAPTURING SYSTEM - An image-capturing system includes: a stage that has mounted and fixed thereon a glass slide on which at least one sample is placed and that circulates in an endless-track shape; a line sensor that scans only a part of the sample; an imaging driving mechanism that moves a relative position of the line sensor and the stage in a direction perpendicular to a scanning direction of the line sensor; and an optical system that focuses an image of the sample on the line sensor. | 04-14-2011 |
20110128595 | SCANNING SPEED ADJUSTING METHOD AND SCANNING SYSTEM - A scanning speed adjusting method is used in a scanning system including a scanning module and a controller. Firstly, a document is scanned by the scanning module, thereby generating an image data. Then, the image data is received by the controller, and transmitted to an output device. An input speed of receiving the image data from the scanning module and an output speed of transmitting the image data to the output device are detected by the controller. If the input speed and the output speed are different, a scanning speed of the scanning module is adaptively adjusted according to a difference between the input speed and the output speed. | 06-02-2011 |
20120075680 | SCANNING SPEED CONTROL DEVICE AND METHOD - A control device and a method for controlling scanning speed of a scanner. The control device includes a decision device and a driving device. The decision device further includes an image buffer, an up-down counter and a comparator. The decision device receives the input image data and utilizes the up-down counter to compute data access volume inside the image buffer. The comparator decides whether to increase or decrease the scanning speed according to the data access volume and also outputs decision data to the driving device. | 03-29-2012 |
20130188230 | IMAGE FORMING APPARATUS - An image reading apparatus includes a sheet feeding unit configured to sequentially feed documents loaded on a document positioning plate, a reading sensor configured to read a document of the plurality of documents fed by the sheet feeding unit, an acquisition unit to acquire an interval of the document between a trailing edge of a preceding document and a leading edge of a next document conveyed through the conveyance path, and a reading unit to execute a first reading mode using the reading sensor to read the document conveyed at a first conveyance speed, and a second reading mode using the reading sensor to read the document conveyed at a second conveyance speed that is lower than the first conveyance speed, wherein the reading unit executes the second reading mode after the first reading mode when the interval of the document is less than a predetermined interval. | 07-25-2013 |
