Abstract
A display apparatus displaying gray scale by using a subfield method has a main path, a sub path, a switch circuit, a motion region detection circuit, a first judging circuit, a level detection circuit, a motion detection correction circuit, and a second judging circuit. The switch circuit outputs a first image signal generated by the main path or a second image signal generated by the sub path by switching therebetween, and the first judging circuit outputs a first motion signal in accordance with an output of the motion region detection circuit. The motion detection correction circuit receives the first motion signal and a level signal, and outputs a second motion signal in accordance with the level signal, and the second judging circuit receives the second motion signal and the level signal, and outputs a switching control signal to the switch circuit.
