Abstract:
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.
