A de-interlacing device capable of de-interlacing a video field adaptively
and associated method, the device includes a video field detector for
detecting a video field and for outputting a motion detection parameter,
a motion detector for detecting a motion difference between the video
frame and at least one video frame neighboring the video frame, and for
determining a motion ratio for the motion difference according to the
motion detection parameter, and a de-interlacing unit for de-interlacing
the video field according to the motion ratio output from the motion
detector.
