ABSTRACT:
To provide an image processing device able to generate a progressive image signal in high quality based on an interlaced image signal and an image processing method for the same, wherein a continuity detection circuit detects continuities in the interlaced image signal and to the field image signal, a moving circuit moves one of the field image signals before and behind one field based on a motion vector between the field image signals before and behind one field to generate a first field image signal, and an image signal generation circuit decides a mixture ratio based on the continuity and mixes the first field image signal and a second field image signal based on a line in the field image signal at the mixture ratio to generate a third field image signal included in the progressive signal.
