Publication number: 20100220195Abstract: A method, apparatus, and system for updating video data are disclosed herein. The first method disclosed herein includes: the MP receives an indication from the MC, detects the video quality of the video source, and requests the video data to be updated from the MC according to the detection result. The second method includes: the MP receives an indication sent by the MC and performs detection; and requests video data to be updated from the MC after detecting an in-band video data update request sent by a video source. The third method includes: the MP sends an in-band video data update request to the video source specified by the indication according to the indication sent by the MC, requesting to update the video data specified by the indication. Through the present invention, the MP requests the video data that needs to be updated from the MC.Type: ApplicationFiled: March 19, 2010Publication date: September 2, 2010Inventors: Dong Li, Zhiyong Xu

Publication number: 20100214412Abstract: A method for calibrating an assembly consisting of an omnidirectional camera (2) located on a vehicle (1) and an optical display unit. An image displayed by the display unit reproduces a perspective of an imaginary virtual camera above the object (1), an image from the virtual camera is projected into an object coordinate system and resulting coordinates (XW, XW.Y) are projected into the omnidirectional camera. During the projection of the image of the virtual camera into the object coordinate system, pixels (xp) of the image of the virtual camera within an imaginary circle or ellipse (1) around the object are projected onto an imaginary plane, while pixels (xp) of the image outside the circle or ellipse are transformed by the virtual camera into the object coordinate system in such a way that they are projected onto an imaginary surface that rises from the edge of the circle or ellipse.Type: ApplicationFiled: September 23, 2008Publication date: August 26, 2010Applicant: DAIMLER AGInventor: Tobias Ehlgen

Publication number: 20100208079Abstract: Various systems and methods for comparing media signals are disclosed. In some embodiments, media signals are compared by identifying characteristic features in the respective signals and then analyzing the characteristic features to determine if the signals contain corresponding content. In other embodiments, the characteristic features are analyzed to determine the extent to which the signals are synchronized in time.Type: ApplicationFiled: February 12, 2010Publication date: August 19, 2010Inventor: Jeff Wei

Publication number: 20100208081Abstract: A moving image output method includes the steps of: detecting the difference between adjacent frames of moving image data; determining the level of each frame of the moving image data based on the difference detected; monitoring predetermined various conditions; and selectively executing three operation modes based on the result of the monitoring. The three operation modes are a normal mode in which video output data is output with the number of frames of the moving image data not increased or decreased, a skipping mode in which a particular frame of the moving image data is skipped based on the level of each frame of the moving image data, and a high quality mode in which an intermediate frame is generated and inserted between the adjacent frames for which the difference is equal to or greater than a predetermined value.Type: ApplicationFiled: January 22, 2010Publication date: August 19, 2010Applicant: SONY ERICSSON MOBILE COMMUNICATIONS ABInventor: Kenji TOKUTAKE

Publication number: 20100194895Abstract: A digital image acquisition device has an image acquisition sensor, a shutter, an aperture and optical elements for focusing an image on the sensor. The device includes a light source located in the body of the device. The light source is periodically activated with one of the aperture or shutter closed, and the device derives a map of defects on the surface of the sensor from a calibration image acquired by the sensor when illuminated by the light source.Type: ApplicationFiled: April 6, 2010Publication date: August 5, 2010Applicant: FOTONATION VISION LIMITEDInventors: Eran Steinberg, Adrian Zamfir, Stefan Petrescu

Publication number: 20100194886Abstract: A camera calibration device performs camera calibration for projecting a plurality of camera images from a plurality of cameras onto a predetermined surface to combine them on the basis of the results after calibration patterns to be arranged in a common photographing area of the cameras are photographed by each of the cameras. The camera calibration device judges where or not the calibration patterns are observed by the cameras on the basis of the photographed results. If judging that the calibration patterns are not observed, the camera calibration device creates the content of an instruction to contain the calibration patterns in the common photographing area to allow the cameras to observe the contained calibration patterns on the basis of the photographed results and notifies the instruction content to an operator who is in charge of the arrangement operation of the calibration patterns.Type: ApplicationFiled: September 24, 2008Publication date: August 5, 2010Applicant: Sanyo Electric Co., Ltd.Inventors: Keisuke Asari, Yohei Ishii
