ABSTRACT:
In a time axis converting section 10, time axis conversion processing of 4/3 times is implemented to a digital picture signal of a first data rate indicating an image of a first aspect ratio (16:9) to thereby generate a digital picture signal of a second data rate indicating an image of a second aspect ratio (4:3). In a data rate converting section 20, data rate conversion processing of conversion ratio of 3:4 is implemented to the digital picture signal of the second data rate to thereby generate, from the digital picture signal of the first data rate indicating the image of the first aspect ratio (16:9), a digital picture signal of a first data rate indicating the image of the second aspect ratio (4:3).
