Patent ID: 7446818

Claim:
An apparatus for detecting film mode of video data, comprising: at least one motion estimation module, each the motion estimation module comprising: a pixel motion estimator receiving a first field and a second field in the video data, and performing a motion estimation operation on a target pixel region in the first field and the second field to generate a pixel motion determining value corresponding to the target pixel region; and a field motion decision coupled to the pixel motion estimator for generating a field motion determining value corresponding to the first field according to the pixel motion determining values; and a film mode detector coupled to the motion estimation module for determining the film mode of the video data according to the field motion determining value corresponding to the first field; wherein the pixel motion estimator comprises: a pixel motion estimating unit estimating a corresponding position in the second field according to the target pixel region of the first field, and generating an estimating result according to the corresponding position and the position of the target pixel region; and a first determining unit coupled to the pixel motion estimating unit for generating the pixel motion determining value according to the estimating result.
