<p>A motion vector detection method includes a step (S300) of generating a first motion vector candidate MVC1 based on a reference frame Rf1 and a second motion vector candidate MVC2 based on a reference frame Rf2, steps (S302, S304) of generating an interpolation prediction block PB0 by interpolating pixel values according to the prediction block PB1 indicated by the first motion vector candidate MVC1 and a prediction block PB2 indicated by the second motion vector candidate MVC2, steps (S306 to S310) of calculating a prediction error evaluating value based on the difference between pixel values of the interpolation prediction block PB0 and the block to be encoded, and steps (S312, S314) of detecting the first and the second motion vector candidates MVC1, MVC2 making the prediction error evaluation value minimum as the motion vector MV1 and motion vector MV2 of the block to be encoded.</p> |
