| 20080279278 | METHOD OF DOUBLING FRAME RATE OF VIDEO SIGNALS - A method for doubling the frame rate of video signals creates an interpolated video frame using a current frame and a previous frame. First, the current frame is sequentially received. The interpolated frame is inserted between a previous frame and the current frame, in which values for each pixel in the interpolated frame are derived from a first reference pixel in the current frame biased by a positively weighted difference between the first reference pixel and a second reference pixel in the previous frame. | 11-13-2008 |
| 20080284908 | APPARATUS AND METHOD FOR FRAME RATE UP CONVERSION - An apparatus for frame rate up conversion comprises a motion-compensated frame rate converter, a primitive frame rate converter and a determination circuit. The determination circuit designates either the motion-compensated frame rate converter or the primitive frame rate converter to output an interpolated frame according to an index that estimates an output quality of the motion-compensated frame rate converter. | 11-20-2008 |
| 20080304568 | METHOD FOR MOTION-COMPENSATED FRAME RATE UP-CONVERSION - The method for motion-compensated frame rate up-conversion includes the step of detecting a film-mode video signal comprising a sequence of 3-2 pull-down frames, and extracting a sequence of feature frames from the sequence of 3-2 pull-down frames. In addition, a motion vector for each pair of the sequence of feature frames is calculated. Also, a plurality of intermediate frames between each pair of the sequence of feature frames is interpolated based on the corresponding motion vector. | 12-11-2008 |
