摘要： During image processing of video pictures, it is generally necessary to have fast, repeated access to adjacent picture blocks. Picture memories with a sufficient capacity to store complete video pictures do not have the necessary access time to perform image processing in real time. The invention therefore provides for the writing of picture blocks from a picture memory to a fast access memory. Only the pixels in the access memory are accessed when the image processing operation is performed. During the read-out, a further block from the picture memory is simultaneously read into the access memory. As a result, fast access to the picture data is possible in conjunction with little additional outlay in respect to memory. Areas of application for the method are in the image processing of video pictures.

摘要： Virtually complete freedom from flicker is achieved by converting a line-interlaced 50/60 Hz video signal to a progressive 100/120 Hz video signal. For this purpose, the video signal on the input side is first converted to a 100/120 Hz signal with line-interlaced fields, and the progressive video signal is then produced from the first converted signal taken together with the non-converted input signal.

摘要： A method for detecting a video signal that represents an image sequence and exhibits linewise repeated video data comprises selecting a plurality of line groups each having a first, a second and a third line, which originate from two consecutive fields in the case of a field sequence and from one field in the case of a frame sequence. The method determines for each line group a first line-distance measure for a difference between video contents of the first and second lines and a second line-distance measure for a difference between video contents of the second and third lines. The method then interprets the first and second line-distance measures with regard to the presence of a significant difference between these line-distance measures.

摘要： An image to be interpolated is subdivided into a number of image blocks and a motion estimation technique is implemented to provide at least one initial motion vector for each of the image blocks. A modified motion vector is generated for each image block based on the initial motion vectors assigned to the individual image blocks. At least one additional image block is determined through which the motion vector assigned to the given image block passes at least partially, and the modified motion vector is generated as a function of the initial motion vector that is assigned to this at least one additional image block.

摘要： The invention relates to a method and a device for simultaneously representing at least a first and a second sequence of pictures (M, S) in an overall picture. The inventive method is characterised in that picture data belonging to a picture of the first sequence of pictures (M) is stored in the form of a first picture data signal in a first picture memory (SPM). Picture data belonging to a picture of the second sequence of pictures (S) is stored in the form of a second picture data signal in a second picture memory (SPS). The picture data of the first and second picture data memory is read out according to a periodic screen signal (RS), whereby phase shift (SHIFTM, SHIFTS, tx) of the screen signal (RS) can be adjusted according to the first and/or second picture data signal.

摘要： A time-discrete picture signal is formed from an analog picture signal, such as a luminance signal or a chrominance signal. Corresponding to the time-discrete picture signal, a time-discrete filter signal is formed, specifically a so-called “peaking signal,” which has a sequence of peaking signal values, of which one value each is associated with one signal value of the time-discrete picture signal. The discrete peaking signal is formed by a digital peaking filter from the discrete picture signal or by an analog peaking filter from the analog picture signal during subsequent sampling of the analog peaking signal. The peaking filter increases the amplitude of selected frequency components of the picture signal.
