1. A method for converting interlacing video information into progressive video information, comprising:

  • providing first interlacing field data comprising a plurality of pixel lines;

    providing second interlacing field data comprising a plurality of pixel lines which second interlacing field data is temporally displaced from the first interlacing field data;

    selecting one of the first and second interlacing field data to be a selected interlacing field data and a remaining one of the first and second interlacing field data to be a reference interlacing field data;

    adding additional pixel information to the selected interlacing field data, which additional pixel information comprises modified interlacing field data;

    selecting a first region comprising a plurality of pixels in the modified interlacing field data;

    selecting a first plurality of comparison regions, each comprising a plurality of pixels, in the reference interlacing field data;

    comparing each comparison region of the first plurality of comparison regions with the first region to identify a first comparison region that most closely corresponds to the first region;

    selecting a second region comprising a plurality of pixels in the modified interlacing field data, which second region partially overlaps with the first region;

    selecting a second plurality of comparison regions, each comprising a plurality of pixels, in the reference interlacing field data;

    comparing each comparison region of the second plurality of comparison regions with the second region to identify a second comparison region that most closely corresponds to the second region;

    using at least information corresponding to the first comparison region and the second comparison region to convert the selected interlacing field data into progressive video information.
