<P>PROBLEM TO BE SOLVED: To reduce waste of electric power in respective states of a processing section, under assumption that the processing section makes transitions between a plurality of states with at least different power supply modes, when power supply to the processing section is controlled according to the detecting state of a mobile body. <P>SOLUTION: As basic functions, a first human sensor 28 and a second human sensor 30 have: a transition control to a standby mode (an operation mode 1) by detecting a mobile body (a user) during a sleep mode; a partial power-saving control in a running mode (an operation mode 2) for increasing an energy saving object, when the user temporarily moves away from an image processor 10; and a transition control to the sleep mode (an operation mode 3) by detecting no mobile body (no user) during the standby mode, the transition control being performed combined with a transition control by a timer. <P>COPYRIGHT: (C)2013,JPO&INPIT |
