    摘要: 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). Further, a sub-area video mode (SVM) is determined for said selected sub-area and said local video mode (LVM) is determined for said ticker area (TA) based on said sub-area video mode (SVM).

    摘要: 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.
