ABSTRACT:
In a display apparatus, a luminance acquiring unit acquires luminance signals from inputted image signals. A difference calculating unit compares luminance signals of the current frame acquired by the luminance acquiring unit with those of a previous frame stored in a frame memory, and then takes a difference between these luminance signals. If the difference of the luminance is large, a judging unit judges that the image corresponding to a portion in question is moving. If the difference of the luminance is small, the judging unit judges that the image corresponding to the portion stays still. A gain calculating unit gradually lowers the luminance corresponding to a part where the image stays still, and gradually restores to the original level the luminance corresponding to a part where the image is moving.
