Patent ID: 7860170

Claim:
A moving-picture scanning-type conversion apparatus comprising: a scanning-type setter to set a scanning type for each frame of a progressive moving picture incoming at a given picture rate, in accordance with motion activity of the incoming moving picture; a scanning line decimator to decimate scanning lines from the incoming progressive moving picture, thus obtaining an interlaced moving picture at the given picture rate, for each frame; a frame memory to store the incoming progressive moving picture at the given picture rate and output successive two frames of the same progressive moving picture at the given picture rate; a line decimator to decimate scanning lines of frames of the incoming progressive moving picture, by separating even and odd scanning lines of the two frames, thus obtaining an interlaced signal that carries a progressive moving picture at a picture rate that is half of the given picture rate; and a switch to switch the obtained interlaced moving picture and the obtained progressive moving picture carried by the interlaced signal in accordance with the set scanning type, for each frame.
