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： In a method and apparatus for motion-vector-aided interpolation of a pixel in an intermediate image lying temporally or spatially between first and second images, motion vectors are assigned to the pixel to be interpolated, one pixel in each image being assigned to each vector. Video information values (e.g., luminance or chrominance values) are determined based on the video information values of pixels assigned to the motion vectors. A further video information value is generated by mixing certain of the video information values, and other video information values form a value interval, the mathematical position of the further video information value being determined relative to the interval boundaries. The video information value to be interpolated is determined depending on the position of the further video information value relative to the interval boundaries.

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： The invention relates to a method and a device for interpolating a pixel of an interline of a first field in a sequence of interlaced fields. The method comprises selecting at least one first pixel and one second pixel each from scan lines of the first field adjacent to the interline, and a third pixel from a second field temporally preceding or following the first field, the image position of this pixel corresponding to the image position of the pixel to be interpolated, as well as fourth and fifth pixels which lie vertically adjacent to the third pixel in the second field; generating a first filter value by applying a first filter, which comprises a low-pass filter, to the at least one first and second image information values; generating a second filter value by applying a second filter, which comprises a high-pass filter, to the third, fourth and fifth image information values; generating an image information value of the interpolated pixel by employing the first and second filter values.
