A picture conversion information supply section 130 calculates per frame an affine transformation parameter for picture conversion based on motion information about a moving picture. With reference to a reference picture, a picture conversion section 140 affine-transforms pictures making up the moving picture per frame using the calculated affine transformation parameters. Based on information indicating the center position, angle or scaling factor about the transformed pictures coming from the picture conversion section 140, a sound conversion information calculation section 190 calculates sound conversion information for converting the sound corresponding to the pictures. Based on the sound conversion information, a sound conversion processing section 200 controls the volume of each of the channels making up the sound, adds up the controlled sound of each channel, and outputs the result as output sound to speakers 220. |
