Patent number: 8213718Abstract: A method for video mode detection, wherein video input data (VID) corresponding to a video picture (P) is received and a video mode is determined for said video picture (P). The determining of said video mode depends on a local video mode (LVM) and a global video mode (GVM) of said video picture (P). Said global video mode (GVM) is determined for said video picture (P) based on said video input data (VID) or a derivative (m1) thereof. For determining said local video mode (LVM), first said video picture (P) is subdivided into a ticker area (TA) and a remaining area (RA), thereby generating ticker area data (TAD). Then, said local video mode (LVM) is determined for said ticker area (TA) based on said ticker area data (TAD). When determining said local video mode (LVM), said ticker area (TA) is subdivided into n sub-areas, and at least one of said n sub-areas (1 . . . 6) is selected as selected sub-area (SSA).Type: GrantFiled: March 22, 2007Date of Patent: July 3, 2012Assignee: Sony Deutschland GmbHInventors: Sergio Mayoral, Oliver Erdler

Publication number: 20110299597Abstract: From first and second image data descriptive for first and second pictures captured in a first temporal distance to each other, a global motion estimator unit (110) estimates a global motion vector, which is descriptive for sign and amount of a global displacement of image portions that move with respect to a first axis both when the move at the same speed and when they move at different velocities. The global motion vector improves estimation of fast moving objects. The global motion vector estimation may rely on the evaluation of a plurality of one-dimensional profiles.Type: ApplicationFiled: May 11, 2011Publication date: December 8, 2011Applicant: SONY CORPORATIONInventors: Volker FREIBURG, Altfried DILLY, Yalcin INCESU, Oliver ERDLER

Publication number: 20110149163Abstract: The present invention relates to an image processing method and to a device to process a moving image, which is shot by a predetermined video shooting device, in increments of access units. The imaging blur is represented by a corresponding low-pass filter showing the properties of imaging blur which occurs at the time that said moving image is shot with said video shooting device. According to the present method an inverse filter having inverse properties as to said low-pass filter is generated. A processing is performed to apply said inverse filter to said access unit to be processed. Hereby, the step of generating an inverse filter includes an iterative algorithm in the frequency domain based on the original blurred image and the point spread function.Type: ApplicationFiled: October 29, 2010Publication date: June 23, 2011Applicant: SONY CORPORATIONInventors: Toru Nishi, Oliver Erdler

Publication number: 20110123121Abstract: The present invention relates to a coding parameter independent method for reduction of blocking artefacts in a compressed image or video signal. For this purpose, the image is analysed in the vicinity of the block boundaries in order to measure the existence and strength of blocking artefacts and to detect image areas. Based on the analysis result map information for each pixel adjacent to a block boundary is generated. The filter mode for each block boundary is adaptively determined dependent on the map information and the image is filtered depending on the chosen filter mode.Type: ApplicationFiled: September 30, 2010Publication date: May 26, 2011Applicant: Sony CorporationInventors: Paul Springer, Oliver Erdler, Martin Richter, Carsten Dolar
