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 multimedia device and a motion compensation method thereof are provided for generating a middle frame between two frames. The multimedia device includes an interpolation unit, a linear process unit and a combination unit. The interpolation unit generates a first reference pixel data according to the relationship among a first pixel data, a second pixel data, and a third pixel data. The first and the second pixel data are obtained according to the location of a to-be-generated pixel and a relative motion vector. The third pixel data is obtained according to the two pixels data. The linear process unit provides a linear combination of the first and the second pixel data to generate a second reference pixel data. The combination unit combines the two reference pixel data according to the difference between the first and the second pixel data to generate a pixel data for the to-be-generated pixel.
