Abstract:
In on embodiment of the present invention, an image displaying apparatus is disclosed which divides 1 frame into plural sub-frame periods, and modifies the image signals in the following manner in the case of receiving an image of a frame in which a region denoted by an image signal α or an image signal close to the image signal α and a region of another image signal β or an image signal close to the image signal β are adjacent to each other. Specifically, the image displaying apparatus carries out display, in at least one sub-frames period A, with a modified image signal so that the difference with the image signal of the other region becomes smaller, and in at least one other sub-frames period B, with a modified image signal so that the difference with the image signal of the other region becomes more significant, in the vicinity of the boundary between the region of the image signal α and the region of the image signal β. In this way, an embodiment of the present invention provides an effect of improvement in moving picture quality of a hold-type display device without causing a decrease in luminance or flicker.
