20090015887 | IMAGE FORMING APPARATUS AND METHOD OF CONTROLLING THE SAME - A sheet of a document is scanned, character objects are extracted from a scan image, the extracted character objects are divided line by line, and the direction of the document is set on the basis of a blank percentage determined according to start and end positions of lines. If the direction of the document is different from that of a previous document, an image processing unit rotates the scan image. | 01-15-2009 |
20100073721 | SCANNER, IMAGE FORMING APPARATUS INCLUDING THE SAME, AND IMAGE PROCESSING METHOD THEREOF - A scanner, an image forming apparatus including the same, an image processing method of the scanner and a printing method of the image forming apparatus. The image processing method includes acquiring an environment image, acquiring a main scan image by scanning a document on a flatbed, and extracting a document image from the main scan image using the environment image when the document is scanned with the cover in an open position. | 03-25-2010 |
20100079822 | DOCUMENT PROCESSING APPARATUS AND METHOD FOR PROCESSING DOCUMENT USING THE SAME - A document processing apparatus, including a symbol-related information acquirement unit which identifies a text area in a scanned document, extracts symbols from the identified text area, and acquires symbol-related information regarding each extracted symbol, a symbol division unit which divides the extracted symbols into several groups based on a preset reference value regarding the symbol-related information, and a key index generation unit which generates a key index by arranging one group of symbols from among the divided groups. Accordingly, a user can look for a desired document more easily and conveniently. | 04-01-2010 |
20110064310 | IMAGE FORMING APPARATUS THAT AUTOMATICALLY CREATES AN INDEX AND A METHOD THEREOF - An image forming apparatus capable of automatically creating an index, and a method for the same. The image forming apparatus includes a scan unit to scan a document, a text/image separation unit to separate the scanned document into a text area and an image area and to separate texts in the text area into symbols, an index determination unit to extract one or more properties of the separated symbols and to compare the extracted symbol properties with one or more index thresholds to determine whether text including the symbols is an index object, and an index page creation unit to create an index page including the text determined as the index object and information about a page including the text that corresponds to the index object. Accordingly, since the index page is automatically created, main contents of each page of the document can be easily selected and/or presented. Also, a search for desired contents in the document is facilitated by a link between the index page and original contents of the pages in the document, thereby improving user convenience. | 03-17-2011 |
20110069335 | IMAGE PROCESSING APPARATUS AND METHOD - An image processing method includes determining one or more candidate pixels having variation of brightness in a first direction, among a plurality of pixels constituting an input image, the variation of brightness exceeding a first reference value, determining a certain region in which the total number of candidate pixels existing in a row of pixels in a second direction different from the first direction exceeds a second reference value, and generating an output image free from the determined certain region. | 03-24-2011 |
20110158545 | APPARATUS AND METHOD OF MATCHING SYMBOLS IN A TEXT IMAGE CODING AND DECODING SYSTEM - An apparatus of a text image coding and decoding system includes a matching unit to compute a first distance between a symbol of a text image with a reference symbol of a symbol dictionary, to determine whether the symbol matches with the reference symbol according to the first distance and a first reference, and to compute a second distance between the one of the symbols with the reference symbol if the symbol does not match with the reference symbol according to the first distance and the first reference, and to determine whether the symbol matches with the reference symbol according to the second distance and a second reference. | 06-30-2011 |
20120300227 | APPARATUS AND METHOD OF SEGMENTING AN IMAGE IN AN IMAGE CODING AND/OR DECODING SYSTEM - An apparatus usable in an image encoding and/or decoding system includes a segmentation unit to convert a first image of a first resolution into a second image of a second resolution, to segment the second image of the second resolution with one or more blocks of a binary mask layer having a foreground and a background, and to convert the segmented second image into a third image of a third resolution as a segmented image. | 11-29-2012 |
20130057926 | IMAGE COMPENSATION IN REGIONS OF LOW IMAGE CONTRAST - To compensate an image, a profile thereof is obtained from pixel values in a marginal area of the image. A background value of the image determined from the profile and correction to the image is performed in accordance with the background value and the profile. | 03-07-2013 |
20140139856 | PRINTING CONTROLLING TERMINAL APPARATUS, IMAGE FORMING APPARATUS AND METHOD FOR CONTROLLING PRINTING USING THE SAME - A printing controlling terminal apparatus, an image forming apparatus, and a printing controlling method thereof are provided. The printing controlling terminal apparatus includes a user interface that receives a command to print regarding a document, a determiner that determines if the document intended by the command to print is printed in color, a print data generator that generates print data regarding the document according to a result of the determining, and a communicator that transmits the generated print data to an image forming apparatus. The determiner divides each page of the document into a plurality of blocks, extracts color information from each of the plurality of blocks by applying weighted values to color values of the plurality of divided blocks, and determines whether to print the document in color based on the color information. | 05-22-2014 |
20140177004 | IMAGE SCANNING APPARATUS, METHOD FOR IMAGE COMPENSATION AND COMPUTER-READABLE RECORDING MEDIUM - An image scanning apparatus and method are provided. The image scanning apparatus includes a scanner that scans a manuscript to generate a scan image, an image processor that calculates a manuscript boundary on the generated scan image as an equation and compensates a distortion of the scan image using the calculated equation, and a storage member that stores the scan image of which the distortion has been compensated. | 06-26-2014 |
20150062666 | IMAGE FORMING APPARATUS, METHOD FOR PROCESSING IMAGE THEREOF AND NON-TRANSITORY COMPUTER-READABLE RECORDING MEDIUM - An image processing method includes scanning a document, separating a text region from the scanned document and detecting symbols included in the text region, calculating feature values of the detected symbols, selecting a representative value from the calculated feature values, and converting the symbols having the feature values other than the representative value into a preset color or form. | 03-05-2015 |
