<P>PROBLEM TO BE SOLVED: To provide a method for automatically adjusting receiving sensitivity, which can automatically adjust receiving sensitivity according to a peripheral noise in an environment of varying noises, and avoid useless sensitivity adjustment when the peripheral noise varies within the range of fluctuation. <P>SOLUTION: The proposed method for automatically adjusting receiving sensitivity calculates a first sensitivity corresponding to a minimum noise value, based on stepwise relationship between the noise and the sensitivity indicated by a first noise threshold pair stored in a second storage of a computer (S103); and a second sensitivity corresponding to a maximum noise value, based on stepwise relationship between the noise and the sensitivity indicated by a second noise threshold pair, which is a noise threshold pair stored in a third storage of the computer, having a threshold corresponding to each threshold of the first noise threshold pair, and each threshold being set lower than the threshold corresponding to the first noise threshold pair (S104). <P>COPYRIGHT: (C)2009,JPO&INPIT |
