<P>PROBLEM TO BE SOLVED: To reduce radiation of radiowaves to a human body from a wireless information terminal. <P>SOLUTION: A human body detector 112 detects degree of proximity of a wireless digital camera body to a human body. A control unit 101, according to the degree of proximity, outputs control signal S2 for selecting a coupler 108 to reduce radiation of radiowaves from an antenna B111 on the human body side of the wireless digital camera body. The distribution ratio of transmission power between two antennas A110 and B111 is thus changed. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
