Abstract:
1. A method for converting a plurality of interleaved frames to a plurality of progressive frames, wherein each interleaved frame includes two interleaved fields and each interleaved field includes a plurality of pixels, comprising: fetching a previous interleaved field, a current interleaved field, a next interleaved field, and a second next interleaved field; determining a first difference value by calculating the difference between a block of pixels of the current interleaved field and a corresponding block of pixels of the previous interleaved field, a second difference value by calculating the difference between the block of pixels of the current interleaved field and a corresponding block of pixels of the next interleaved field, and a third difference value by calculating the difference between the block of pixels of the current interleaved field and a corresponding block of pixels of the second next interleaved field; generating a first progressive frame by performing a weave method, a second progressive frame by performing a motion compensation method, and a third progressive frame by performing a bob method; and selecting one of the first, the second, and the third progressive frames to be a current progressive frame based on the first, the second, and the third difference values.
