TV receiver and diversity receiving method

摘要

When an antenna (201) which is favorable in receiving state is selected from among a plurality of antennas (201) by an antenna selector (202), white noise is caused in a video signal (Vout) by AGC characteristics of an AGC circuit (203a) in a tuner (203), and displayed on a display screen. A switching control unit (206) exercises luminance altering control for a luminance altering unit (204) on the basis of an output level difference or the like of the AGC circuit (203a) , lowers luminance of a white noise generating region only during a white noise generating interval, and thereby makes the white noise inconspicuous.
