PROBLEM TO BE SOLVED: To provide a mobile television receiver provided with a plurality of antennas that can reduce a noise on a video image due to switching of the antennas. SOLUTION: A changeover control circuit 16 selects an antenna in the best reception state among a plurality of antennas 1-14 according to a change in the reception state and also outputs an antenna switching signal SWON to throw a changeover switch 27 to select a larger filter coefficient K for a frame cyclic filter 24. Thus, the S/N of the filter can be improved to reduce a noise on a video image that is displayed. When the reception state is good, the antenna switching signal SWON is inactivated to prevent the changeover switch 27 from being uselessly switched.
