Abstract: According to the present invention, it is possible to carry out the optimum correction of moving images in the frame even if the movement of objects in the frame is not uniform in a subfield light-emitting type display. The motion vector detecting module detects the motion vector of pixels among the frames relating to the input image signal. The motion vector correcting module replaces the motion vectors V of all the pixels in the frame with a specific motion vector Vm, when the distribution of the motion vectors V in the frame detected is biased to the specific motion vector Vm. The subfield correcting module corrects the light-emitting positions of the subfield light-emitting pattern according to the motion vectors outputted by the motion vector correcting module.
