<p>In a motion prediction/compensation unit (32), when reference image data is used to carry out motion compensation and generate predicted image data on the basis of motion vectors detected by motion detection, a compensation control unit (3231) switches filter coefficients supplied to a filter unit (3233) from a coefficient table (3232) in response to loop filter processing on the reference image data used for the generation of the predicted image data. For example, when loop filter processing is not carried out, the reference data undergoes filter processing using a filter characteristic having high noise reduction intensity. Thus, predicted image data having little noise can be generated, and deterioration of the quality of predicted images and reduction of compression efficiency can be inhibited.</p> |
