Patent number: 10628916Abstract: An image generating apparatus for generating an output image based on an input panorama image, includes a parameter input unit inputting an output range parameter and a correction parameter, the output range parameter designating an output range in the panorama image, the correction parameter designating a correction part to be corrected in the output image; and an image correction unit correcting the correction part designated by the correction parameter in the output image. Further, the image correction unit calculates a similarity between the correction part and peripheral pixels and corrects the correction part based on the similarity and the peripheral pixels, and the output image is generated from the output range of the panorama image and is the panorama image corrected by the correction.Type: GrantFiled: November 8, 2018Date of Patent: April 21, 2020Assignees: Ricoh Company, Ltd., National University Corporation Nara Institute of Science and TechnologyInventors: Daisuke Nakagawa, Norihiko Kawai, Tomokazu Sato, Naokazu Yokoya

Publication number: 20070008499Abstract: A data processing device calculates an image conversion parameter corresponding to each partial image. According to the image conversion parameter calculated, a partial image which has been imaged according to the current partial image is geometrically converted. The images are combined to generate a mosaic image. Moreover, the current partial image and at least a part of the mosaic image generated are displayed on a display unit.Type: ApplicationFiled: September 7, 2004Publication date: January 11, 2007Inventors: Akihiko Iketani, Noboru Nakajima, Tomokazu Sato, Sei Ikeda, Masayuki Kanbara, Naokazu Yokoya

Patent number: 5881170Abstract: The present invention provides a contour extraction apparatus which has an image storing section 1 for storing an image, a contour model storing section 2 for storing a contour model, a contour model transforming section 3 for transforming and shrinking the contour model according to a prescribed rule, a contour model intersection detecting section 4 for detecting a contact or intersection in the contour model, a contour model dividing section 5 for dividing the contour model into contour models based on the detected contact or intersection, and an extraction completion judging section 7 for judging whether or not extraction of the contour of the object has been completed. According to the contour extraction apparatus, even when there are objects whose contours are to be extracted, the contour of the each object can be extracted correctly by predesignating a region only once, or without predesignating a region at all, despite the presence of excessive noise or a discontinuity in the edge.Type: GrantFiled: March 22, 1996Date of Patent: March 9, 1999Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Shoichi Araki, Naokazu Yokoya
