摘要： A method and a circuit arrangement for picture-in-picture insertion are described, in which, in order to prevent a write operation from being overtaken by a read operation and also to avoid the associated picture disturbances, a field is stored under an address which precedes a previous field by a number of N lines. A read address is then shifted to the same line of the older field in the event of a minimum distance to a write address being undershot.

摘要： A method for picture-in-picture insertion is described, which is distinguished in particular by the fact that the inset pictures are written to a memory device (2) in a circulating manner under continuously incremented write addresses, the first and last address of each written-in inset picture is stored, an overtake signal is formed by comparing the instantaneous address with the previously stored address, said signal indicating whether a previous address has been reached again and, consequently, the corresponding picture content has been overwritten, by evaluation of the overtake signal, the current or preceding segment is selected for read-out depending on whether or not overtaking took place before the start of the read-out, and the inset picture stored in the selected segment is read out with continuously incremented read addresses and is inserted into the main picture. A corresponding circuit arrangement is also described.

摘要： The invention relates to an iterative method for determining an interpolated image information value in an image that comprises a number of image regions arranged in a matrix-like fashion having original image regions to which one image information value has been assigned, and having at least one image region to be interpolated. In order to determine an interpolated image information value, the method specifies a starting interpolation direction and determines a quality measure for the starting interpolation direction. At least one image direction is selected different from the starting interpolation direction and determining a quality measure for this at least one image direction. The quality measures for the starting interpolation direction are compared and the at least one image direction different from the starting interpolation direction, selecting as the interpolation direction the starting interpolation direction or the at least one image direction, and determining the interpolated image information value using image regions that are located in the interpolation direction adjacent to the to-be-interpolated first image region. The steps of selecting and comparing are repeated at least once.

摘要： A graphic character that has a character matrix with a number of character units that are indivisible at least in either a horizontal direction or a vertical direction is scaled by dividing the character matrix into one first and at least one second character segment, each comprising at least one of the character units. The first character segment is symmetrically scaled using a first scaling factor and the second character segment is scaled using a second scaling factor different from the first scaling factor.

摘要： The invention relates to a method and an apparatus for increasing the resolution of a data sequence, such as for example a video data sequence. Between two data values of a given data sequence at least one intermediate value is interpolated by applying low-pass filtering and at least one first and one second high-pass filterings to data values of the data sequence, subjecting the filter values obtained by the high-pass filterings to rank-order filtering and combining the filter result so obtained with the filter result obtained by low-pass filtering.

摘要： Method for motion-vector-aided interpolation of a pixel of an intermediate image lying between two input images includes a first pixel being selected from a first field and a second pixel being selected from a second field using a first motion vector, and a third pixel being selected from the first field and a fourth pixel being selected from the second field using a second motion vector. Next, an interval specified by video information values of the first pixel and the second pixel or an interval specified by video information values of the third pixel and the fourth pixel is determined and the video information values are mixed such that the video information value of the pixel to be interpolated lies within this interval.

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： A method and device for interpolating a pixel of an interline of a first field in a sequence of interlaced fields includes selecting at least one first pixel and one second pixel from scan lines of the first field adjacent the interline, and a third pixel from a second field temporally preceding or following the first field. The image position of the third pixel corresponds to the image position of the pixel to be interpolated. Also selected are fourth and fifth pixels which lie vertically adjacent the third pixel in the second field. A first filter value is generated by low-pass filtering the at least one first and second image information values. A second filter value is generated by high-pass filtering the third, fourth and fifth image information values. An image information value of the interpolated pixel is generated using the first and second filter values.
