A first signal path including a first LNA 3 and a second signal path including an antenna damping circuit 4 and a second LNA 5 are connected in parallel, and switching into either the first signal path or the second signal path is carried out to control a gain of a received signal.

As a result, the apparatus of this invention can generate output image data having a frame rate twice that of the input image data.
