Publication number: 20070159527Abstract: A method and apparatus of correcting geometric information and providing a panoramic view. In the method of providing a panoramic view, a tilting vector (X?, Y?) is generated by applying matrices H(a,b) and HF to a source image vector (X,Y). The matrix H(a,b) is defined by distortion angles “b” towards a plane direction and a distortion angle “a” towards a depth direction of the source image, and the matrix HF is defined according to a camera parameter matrix K. Also, a two-dimensional vector (x,y) of a source image is converted into a three-dimensional vector (X,Y,W) on a retinal image plane having a unit radial distance from an origin of a ground plane. Also, a warped image width (WIW) is estimated from a width and a field of view (FOV) of the source image. A warping vector (x?,y?) is generated based on the converted vector (X,Y,W) and the WIW.Type: ApplicationFiled: October 17, 2006Publication date: July 12, 2007Applicant: Samsung Electronics Co., Ltd.Inventors: Keun Ho Kim, Do Kyoon Kim, Seok Yoon Jung, Hee Sae Lee, Anton Konouchine, Vladimir Vezhnevets

Publication number: 20070140357Abstract: A method for treating a video signal including a plurality of consecutive video fields; at least some video fields of the plurality of video fields contributing to a plurality of substantially successively occurring motion sums; includes: (a) Effecting successive comparison of selected of the motion sums with at least one motion sum threshold in a predetermined cycle. The motion sum threshold is related with at least one earlier-occurring motion sum. The predetermined cycle establishes the successive comparison for evaluating whether the selected motion sums occur in a pattern characteristic of film mode content. (b) Treating the video signal as containing film mode content so long as the successive comparison indicates film mode content. (c) Treating the video signal as not containing the film mode content when a predetermined number of the successive comparisons indicate no film mode content.Type: ApplicationFiled: November 22, 2006Publication date: June 21, 2007Inventor: Clay D. Montgomery

Patent number: 7218895Abstract: A method includes receiving one or more test signals at a first gateway from a second gateway. The method also includes comparing the one or more test signals to one or more expected signals. In addition, the method includes generating a score representing a voice quality supported by the first gateway on a path from the first gateway to the second gateway. The score is based at least partially on the comparison.Type: GrantFiled: November 14, 2002Date of Patent: May 15, 2007Assignee: Cisco Technology, Inc.Inventor: Jayasimha M. Raghavan

Patent number: 7215872Abstract: An image-effect apparatus which provides high quality motion pictures and image effects such as supper slow motion based on a small amount of image data. An image input unit inputs a first image and a second image. A matching processor performs pixel matching between the first image and the second image, and a result thereof is recorded as a corresponding point file. An intermediate image generator generates an intermediate image between the first image and the second image based on the corresponding point file. A speed controller controls the number of intermediate images to be generated, based on a user's instruction. As the number of intermediate images generated is increased, slow motion and super slow motion images are produced.Type: GrantFiled: November 28, 2001Date of Patent: May 8, 2007Assignee: Monolith Co., Ltd.Inventors: Kozo Akiyoshi, Nobuo Akiyoshi, Yoshihisa Shinagawa

Patent number: 7167280Abstract: A method of transferring an image recorded on a photographic film to a digital signal, using a film scanning device that generates scan data representative of the digital signal, comprises the steps of calibrating the film scanning device in relation to printing densities and scanning the photographic film with the film scanning device to produce scan data that represents printing densities. Inasmuch as the digital signal is used to drive a film recorder that exposes an output film that is subsequently printed onto a target print material, the scan data represents printing densities which when written out to the film recorder will produce printing densities of the output film onto the target print material that are identical to the printing densities of the same photographic film optically transferred onto the target print material.Type: GrantFiled: October 29, 2001Date of Patent: January 23, 2007Assignee: Eastman Kodak CompanyInventors: Mitchell J. Bogdanowicz, Christian Lurin, Kyle J. Alvut

Patent number: 7133064Abstract: A method for a 3:2 pull-down film source detection. First, a source is received. Then, field differences of two fields of the same type in the source and an average field difference according to the field difference corresponding to at least one prior field in the source are calculated. The source is established as a 3:2 pull-down film source by checking whether a 3:2 pull-down signature is in the source according to the field difference and the average field difference, and a bad editing point is detected according to an interlaced frame information of the source.Type: GrantFiled: January 25, 2006Date of Patent: November 7, 2006Assignee: Silicon Integrated Systems Corp.Inventor: Wen-Kuo Lin
