20100253789 | PORTABLE TERMINAL APPARATUS, IMAGE OUTPUT APPARATUS, CAPTURED IMAGE PROCESSING SYSTEM, AND RECORDING MEDIUM - A portable terminal apparatus consecutively more than once captures images of an identical image capture object. The portable terminal apparatus determines whether or not a plurality of pieces of captured image data captured include a combination of a given number (an integer not less than 2) of pieces of captured image data which are applicable to be subjected to the high resolution correction by the correction processing section and are offset by a given amount, and transmits, to an image output apparatus, the given number of pieces of captured image data which are determined to be the combination. The image output apparatus receives the given number of pieces of captured image data from the portable terminal apparatus, and carries out, in accordance with the given number of pieces of captured image data, the high resolution correction for preparing high resolution image data which has a higher resolution than the given number of pieces of captured image data received. Thereafter, the image output apparatus carries out an output process for outputting the high resolution image data prepared. This provides a captured image processing system which allows an image output apparatus to output an image captured by a portable terminal apparatus while the image is improving in resolution such as text readability. | 10-07-2010 |
20100253790 | IMAGE OUTPUT APPARATUS, PORTABLE TERMINAL APPARATUS, AND CAPTURED IMAGE PROCESSING SYSTEM - An image output apparatus receives a single piece of captured image data from a portable terminal apparatus, and carries out, in accordance with the single piece of captured image data received, a high resolution correction for creating high resolution image data which has a higher resolution than the single piece of captured image data. Then, the image output apparatus carries out an output process in which the high resolution image data created is outputted. This provides a captured image processing system which allows an image output apparatus to output an image captured by a portable terminal apparatus while the image is improving in resolution such as text readability. | 10-07-2010 |
20110025860 | IMAGE OUTPUT APPARATUS, CAPTURED IMAGE PROCESSING SYSTEM, AND RECORDING MEDIUM - An object extraction section of an image output apparatus determines as an extraction region either (a) a quadrangular region enclosed by a quadrangle in which all internal angles are less than 180° and sides are constituted by 4 edge pixel groups each in the form of a line segment, the 4 edge pixel groups being indicated by edge information, or (b) a polygonal region enclosed by a polygon in which all internal angles are less than 180° and sides are constituted by at least one edge pixel group in the form of a line segment, which edge pixel group is indicated by the edge information, and at least one line segment located on an end portion of the captured image, and then (ii) cuts out, as output target image data, image data of the extraction region from the captured image data. This makes it possible to accurately and easily extract, from a captured image, a region including a rectangular image capture object that a user desires. | 02-03-2011 |
20110032570 | CAPTURED IMAGE PROCESSING SYSTEM AND RECORDING MEDIUM - A captured image processing system includes: a designation information accepting section for accepting designation information indicative of a location of a designated region in a captured image; a region determination section for determining an output target region in the captured image based on the designation information; and a corrected data preparation section for (i) obtaining a mapping for converting (a) coordinates of pixels in a quadrangle-shaped region having four edge pixel groups, detected in the captured image, serving as sides of the quadrangle-shaped region, the four edge pixel groups each being in a form of a line segment to (b) coordinates of pixels in a rectangular region of a given size and having upper and lower sides of the rectangular region being substantially parallel in a horizontal direction, and (ii) preparing corrected image data with respect to image data corresponding to the output target region in the captured image data, which corrected image data has been subjected to coordinate conversion based on the mapping prepared by the mapping preparation section. This allows easy output of necessary regions included in an image captured by a portable terminal apparatus, and allows output of an image having no geometric distortion even if image capture is carried out obliquely with respect to a captured image object. | 02-10-2011 |
20110063456 | PORTABLE TERMINAL APPARATUS, IMAGE OUTPUT APPARATUS, METHOD OF CONTROLLING PORTABLE TERMINAL APPARATUS, AND RECORDING MEDIUM - The invention accomplishes an image capture apparatus capable of allowing a user to more easily attain, as compared to a conventional image capture apparatus, image data of a captured image which includes no blown-out highlights or loss of shadow detail throughout an entire image. A portable terminal apparatus | 03-17-2011 |
20110085204 | CAPTURED IMAGE PROCESSING SYSTEM, IMAGE CAPTURE METHOD, AND RECORDING MEDIUM - A portable terminal apparatus includes an encoding section for encoding captured image data by use of a reference data table, and the portable terminal apparatus outputs, to an image output apparatus, the captured image data encoded, to which a common code corresponding to the reference data table and an output machine ID set by an entry by a user are attached. Meanwhile, the image output apparatus, in a case where the output machine ID received from the portable terminal apparatus matches its own output machine ID, decodes the encoded captured image data by use of an inverse transformation table corresponding to the common code, and outputs this decoded captured image data. As a result, it is possible to ensure confidentiality of image data that is obtained by capturing an image with the portable terminal apparatus. Furthermore, even if a problem such as failure or the like occurs to an image output apparatus that is designated to output an image, it is possible to output the image from another image output apparatus. | 04-14-2011 |

20080310730 | IMAGE PROCESSING APPARATUS, IMAGE FORMING APPARATUS, IMAGE PROCESSING SYSTEM, AND IMAGE PROCESSING METHOD - There are provided: a pattern detection process section for extracting a partial image made of pixels including a target pixel from input image data; a displaced image generation section for generating a self-displaced image by displacing at least a part of the partial image through a predetermined method; and a matching test determination section for determining whether an image pattern included in the partial image matches an image pattern included in the self-displaced image or not. When the matching test determination section determines that the matching exists, a target pixel in the partial image or a block made of pixels including the target pixel is regarded as a feature point. Consequently, even when image data is subjected to a process such as enlarging and reducing, it is possible to extract a feature point that properly specifies the image data regardless of the enlarging/reducing process. | 12-18-2008 |
20090028436 | IMAGE PROCESSING APPARATUS, IMAGE FORMING APPARATUS AND IMAGE READING APPARATUS INCLUDING THE SAME, AND IMAGE PROCESSING METHOD - A feature point calculating section binarizes the image data to obtain a centroid of a consecutive component in which pixels are connected as a feature point, reverses the image data, obtains a centroid as a feature point from the reversed image data similarly, and adds them as a feature point of the image data. A features calculating section calculates a predetermined invariant based on the feature point containing the feature point obtained from the reversed image data, and calculates a hash value based on the predetermined invariant. A vote process section retrieves a hash table based on the calculated hash value, votes for a document of an index stored in association with the hash value, and accumulatively adds the vote. A similarity determination process section compares the number of votes calculated by the vote process section with a predetermined threshold value to determine a similarity. | 01-29-2009 |

This realizes a control device which (i) authenticates a user in an easy way in which impersonation can be prevented without inconvenient operation, and (ii) prevents another user from accidentally viewing a printed matter. | 06-11-2009 |
