Patent number: 7755645Abstract: Systems and methods provide object-based image inpainting. The object-based inpainting can recover part of a missing object or can synthesize visual objects that are entirely missing. In one implementation, an exemplary system generates a target visual object to be inpainted into an image, by geometrically matching key features with a model visual object that can be selected from the same or another image. Borders of the target object are refined through pixel-based contour deformation and textures for the target object are obtained either by pixel interpolation or by patch-based modeling of pre-existing texture in the image. Graph-cut segmentation rectifies image overlap as the target object is embedded in the image. Poisson editing filters visual seams, and edge filling completes visual gaps around the border of the target object.Type: GrantFiled: March 29, 2007Date of Patent: July 13, 2010Assignee: Microsoft CorporationInventors: Xiaoyan Sun, Dong Liu, Feng Wu, Shipeng Li

Patent number: 7660487Abstract: When an output unit is capable of operation at a frame rate F and a resolution of x×y pixels, an imaging unit or an image input unit converts an image into an imaged frame in an internal data format having the frame rate F and a resolution of ix×jy pixels. An image converter converts the resolution of the imaged frame supplied from the imaging unit or the image input unit into a resolution that can be represented by the output unit, generating an output frame having x×y pixels. At this time, the image converter carries out predetermined resolution conversion based on a moving velocity of the image by blocks each having a predetermined size. Thus, such visual effect that an observer of the image of the output frame perceives the image at a resolution exceeding the actual resolution of the output frame is achieved.Type: GrantFiled: December 7, 2004Date of Patent: February 9, 2010Assignee: Sony CorporationInventors: Seiji Kobayashi, Hideki Oyaizu, Yasutaka Hirasawa

Patent number: 7224404Abstract: A method and apparatus where a source delivers graphics data to a target, which receives and displays the graphics data. The source of the graphics data controls how the graphics data is to be displayed at the target. The source transmits a display control signal prescribing a manner in which the video signal is to be displayed in relation to the graphics data. A target receives the video signal, the graphics signal, and the display control signal, and combines the video signal and the graphics data in the manner prescribed by the display control signal to form a combined display at the target.Type: GrantFiled: July 30, 2001Date of Patent: May 29, 2007Assignee: Samsung Electronics Co., Ltd.Inventors: Cheol-hong An, Do-hyoung Kim

Patent number: 7199836Abstract: As information to be processed at an object-based video or audio-visual (AV) terminal, an object-oriented bitstream includes objects, composition information, and scene demarcation information. Such bitstream structure allows on-line editing, e.g. cut and paste, insertion/deletion, grouping, and special effects. In the interest of ease of editing, AV objects and their composition information are transmitted or accessed on separate logical channels (LCs). Objects which have a lifetime in the decoder beyond their initial presentation time are cached for reuse until a selected expiration time. The system includes a de-multiplexer (1), a controller (2) which controls the operation of the AV terminal, input buffers (3), AV objects decoders (4), buffers (4?) for decoded data, a composer (5), a display (6), and an object cache (7).Type: GrantFiled: February 13, 1998Date of Patent: April 3, 2007Assignee: The Trustees of Columbia University in the City of New YorkInventors: Alexandros Eleftheriadis, Hari Kalva

Patent number: 7154560Abstract: Digital watermarks can serve to indicate copyright ownership of digitized video. When video images are transmitted as transformed by discrete cosine transformation (DCT) for compression, with or without motion compensation, it is advantageous to include a watermark after transformation. To this end, a DCT watermark is generated for optimal visibility based on the original image data, and the generated watermark is superposed on the transformed data.Type: GrantFiled: October 27, 1998Date of Patent: December 26, 2006Inventors: Shih-Fu Chang, Jianhao Meng

Patent number: 7154558Abstract: A display control apparatus includes a display controller for receiving image signals corresponding to a plurality of images, to perform image processing on the image signals, and to synthesize images corresponding to the thus-processed image signals. While the images are displayed in a main picture and a sub-picture, the display controller further displays, adjacently to the sub-picture, a list of a plurality of images.Type: GrantFiled: May 22, 2002Date of Patent: December 26, 2006Assignee: Canon Kabushiki KaishaInventors: Hideaki Yui, Takashi Tsunoda, Makoto Uehara, Toshiaki Itazawa, Eiichi Matsuzaki

Connection device capable of mixing an RGB graphics signal and a YUV video signal and related method
Patent number: 7136078Abstract: A connection device capable of mixing an RGB graphics signal and a YUV video signal. The connection device includes a graphics conversion module for transforming an RGB graphics signal into a YUV graphics signal, and a mixing module connected to the graphics conversion module for receiving a YUV video signal and the YUV graphics signal from the graphics conversion module. The mixing module outputs a YUV signal after mixing the YUV video signal and the YUV graphics signal.Type: GrantFiled: August 31, 2004Date of Patent: November 14, 2006Assignee: VIA Technologies Inc.Inventors: Ira Liao, Lizst Hsu, Stam Chuang -
Patent number: 7119849Abstract: There is provided a multi-screen synthesis apparatus that can execute display of video data and update of an OSD image without causing a user to feel a visual sense of incongruity, and reduce system costs. Periodic video source data and a periodic OSD image data are written into a unified memory reserved for planes. The video source data and the OSD image data are read from the unified memory, based on a synthesis layout, for simultaneous display on a single display in a synthesized state. Video data to be written into the unified memory is decimated in units of a frame on an input video source-by-input video source basis. The decimation of the data is controlled based on display priority of the video data determined based on a multi-screen display layout.Type: GrantFiled: April 1, 2003Date of Patent: October 10, 2006Assignee: Canon Kabushiki KaishaInventors: Hideaki Yui, Takashi Tsunoda

Patent number: 7050113Abstract: A digital video stream is digitally scaled to properly display on a device having a horizontal to vertical aspect ratio different than the source aspect ratio leaving a blank area on the device. Graphic data is digitally scaled separately to extend partially or completely into and therefore use the blank area. A compositing blender digitally combines the two prior to a display encoder which produces analog signals for driving the display device.Type: GrantFiled: March 26, 2002Date of Patent: May 23, 2006Assignee: International Business Machines CorporationInventors: Francesco A. Campisano, David Allen Hrusecky, Bryan Jay Lloyd

Patent number: RE39214Abstract: Text and graphics elements may be alpha blended in a way to reduce flicker when the text or graphics are display by a processor-based television receiver. The alpha values are used to intelligently smooth pixels adjacent the element to create television text and graphics.Type: GrantFiled: December 19, 2003Date of Patent: August 1, 2006Assignee: Intel CorporationInventor: Paul S.

Patent number: RE40606Abstract: In an effective display area, an additional information recognizing part 203 recognizes a standard of a broadcast wave, refers to a ROM 212 and selects a target value, and provides an internal clock of a video data reading part 205 and an internal clock of an OSD data reading part 206 with the target value. At a retrace internal, on the other hand, the additional information recognizing part 203 notifies an additional information synthetic position deciding part 210 of the standard of the broadcast wave. The additional information synthetic position deciding part 210 selects from a ROM 211 a target value for reading the additional information applicable to the notified standard, and outputs the target value to an additional information reading parts 207. When the standard of the broadcast wave is changed, target values corresponding to the changes are responsively selected from the ROM 212 and the ROM 211.Type: GrantFiled: May 25, 1999Date of Patent: December 16, 2008Assignee: Panasonic CorporationInventors: Mikihiko Yamada, Hirotoshi Uehara
