20100033766 | Managing Objects With Varying And Repeated Printed Positioning Information - A system and method for identifying captured written data associated with a writing surface using a pen-based computing system are described. In one embodiment, a series of writing surfaces, such as notebooks, are produced, each including a plurality of pages that have an encoded pattern. In an embodiment, each writing surface is also associated with an identifier recognizable by a smart pen or other data capture device. When the smart pen captures written data from a writing surface, the smart pen determines whether the pen-based computing system includes stored written data previously captured from a writing surface having the same encoded pattern as the writing surface from which written data is currently being captured. | 02-11-2010 |
20100067066 | OUTLINING METHOD FOR PROPERLY REPRESENTING CURVED LINE AND STRAIGHT LINE, AND IMAGE COMPRESSION METHOD USING THE SAME - When generating outline data, the contour pixels of the binarized image data are first extracted. Based on the extracted contour pixels, the contour of the image data is approximated to a straight line. In the straight-line approximation process, the distance between adjacent contour pixels among the extracted contour pixels is calculated. It is determined based on the result of the comparison between the length of the first straight line and the length of the second straight line whether the first straight line is used as a contour of the image data. The first straight line connects the first contour pixel and the second contour pixel adjacent to the first contour pixel. The second straight line connects the second contour pixel and the third contour pixel adjacent to the second contour pixel. | 03-18-2010 |
20100165417 | IMAGE PROCESSING METHOD, IMAGE PROCESSING APPARATUS, AND COMPUTER-READABLE STORAGE MEDIUM - An image processing apparatus judges whether each of a plurality of image areas included in a platen image, which is obtained by reading a platen on which an original is placed, has a characteristic indicating a table. In a case where at least one of the plurality of image areas has the characteristic indicating a table, the image processing apparatus judges that an original is formed of one original and outputs a rectangular area including the plurality of image areas. | 07-01-2010 |
20100238518 | IMAGE-PROCESSING DEVICE, IMAGE-READING DEVICE, IMAGE-FORMING DEVICE, IMAGE-PROCESSING PROGRAM, AND IMAGE-PROCESSING METHOD - An image-processing device includes: an integration unit that, if connection information has been assigned to predetermined corresponding end points of both a first image component and a second image component from among image components, integrates the adjacent image components; a calculation unit that calculates the sum of values, the values being assigned corresponding to the connection information assigned to each end point of the image components in an integrated image component that is composed of a plural image components integrated by the integration unit; and a tabular region extraction unit that, if the value calculated by the calculation unit is equal to or greater than a threshold value corresponding to the number of image components included in the integrated image component, extracts a region of the integrated image component as a tabular region. | 09-23-2010 |
20110134491 | DUPLEXING DOCUMENT HANDLER WITH DEFECT REDUCTION - According to aspects of the embodiments, there is provided methods and systems for correcting illumination defects in document handlers. A document handler successively moves an image-bearing sheet past an image sensor, when the edges of the document passes over the edge guide near a constant velocity transport roll the document tends to flick down onto the image sensor causing a lightness change at the edges. The proposed correction is dynamically adjusting the light source or dynamically adjusting the automatic gain control (AGC) of the imaging sensor. The method comprises characterizing an optical signal reflected from an image-bearing sheet as it passes a scan window, determining the illumination defects in at least one edge region based on the reflected signal, and adjusting the gain of the imaging sensor or the light level during receipt of the optical signal. | 06-09-2011 |
20110157657 | IMAGE PROCESSING APPARATUS, CONTROL METHOD THEREFOR AND PROGRAM - An image processing apparatus which reads a first ticket and a second ticket and performs processing extracted from information on the tickets includes a ticket generation unit configured to extract, from a processing instruction sheet serving as an original document which describes a processing target region in a processing target original document, information regarding the processing target region in order to generate a ticket, and to generate a ticket contents of processing to be performed on the processing target region in a format. The ticket generation unit further extracts information regarding contents of processing instructed to be performed on a region in which a change in contents of processing instructed by the processing instruction sheet to be performed thereon is permitted, and generates a second ticket. | 06-30-2011 |
20120154876 | IMAGE SENSOR UNIT AND IMAGE READER - An illumination device includes a light guide made of plastic, and a light source including a light emitting element whose dominant wavelength is a light emission wavelength in an infrared region, and identifies a banknote. White reference plates are provided at positions that are at opposite ends of a rod lens array and cover respective areas external to an image region across the banknote. A correction coefficient is acquired by calculation. The calculation is made by correcting an illuminance such that IR correction data is substantially identical to IR reference data preliminarily stored in a memory circuit in a signal processor on the basis of IR white reference data representing a white reference illuminance generated from light reflected from the white reference plates. The correction coefficient is used for correcting IR image data when the banknote is read. | 06-21-2012 |
20130120803 | IMAGE PROCESSING APPARATUS, IMAGE PROCESSING METHOD, AND COMPUTER-READABLE MEDIUM - An image processing apparatus, when correcting image data using correction information, corrects skew of the image in the sub-scanning direction that is formed by the image forming unit by correcting the image data also at an end portion of an area where an image forming unit forms the image. | 05-16-2013 |
20140320934 | IMAGE PROCESSING APPARATUS AND IMAGE PROCESSING METHOD - Read image data is divided into a plurality of regions, and a histogram is generated and edges are counted for each region. Blank page detection is performed based on a variance value computed from the histogram of each region. Also, the variance between regions is computed from the edge count of each region, and blank page detection is performed according to the amount of variance. It is then determined whether the document is blank or content based on the result of detection by histogram and the result of detection by edge count. | 10-30-2014 |
20150029561 | SKEW ANGLE DETERMINATION - The skew angle of a document image is determined or estimated. The skew angle is determined or estimated by examining patterns found within a Fast Fourier Transform of a subset of the document image. This technique exploits the internal structure of the document designs to allow fast and accurate skew angle estimation, including for arbitrary document fragments. | 01-29-2015 |
