摘要： A multimedia device and a play mode determination method of the same are provided. The multimedia device includes a frame difference calculation unit, a global threshold determination unit and a play mode determination unit. The frame difference calculation unit calculates the frame difference between two continuous frames to obtain a global variation. The global threshold determination unit determines a film mode threshold corresponding to a film mode and a video mode threshold corresponding to a video mode according to a current frame of the two frames and a previous global variation, and selects a global threshold from the film mode threshold and the video mod threshold. The selected threshold is smaller than the film mode threshold. The play mode determination unit compares the global variation with the global threshold, and enables the multimedia device to enter one of the film mode and the video mode according to the comparison result.

摘要： A motion estimation method is provided for generating a motion vector of a to-be-generated frame between two continuous reference frames. The method includes the following steps. A candidate motion vector is obtained according to the position of a to-be-generated block of a to-be-generated frame. Two first reference blocks are obtained from the two reference frames by extending the candidate motion vector from the to-be-generated block to the two reference frames, respectively. Two second reference blocks are obtained from the two reference frames by extending the candidate motion vector from one reference frame to another reference frame. Whether the candidate motion vector is valid is determined according to the positions of the two reference blocks obtained in each obtaining step. The corresponding motion vector of the to-be-generated block is determined according to the valid candidate motion vector.
