| description | A frame rate converter is provided, and includes a motion vector calculator which calculates a motion vector; a motion error calculator which calculates a motion error level of the motion vector; an interpolation frame output part which generates a repetition interpolation frame, which corresponds to the current frame or the previous frame, and a motion interpolation frame based on the motion vector; and a controller which calculates a frame selection value larger than a preset reference selection value by more than a first level when the motion error level is larger than a reference error level, and calculates a frame selection value smaller than the previous frame selection value by a second level, which is smaller than the first level, when the motion error level is smaller than the reference error level, and controls the interpolation frame output part to output the repetition interpolation frame or the motion interpolation frame based on the calculated frame selection value. |
