<P>PROBLEM TO BE SOLVED: To adjust time to restrict power supply to an activated part which is determined to be in disuse by time measurement, according to relative position between a user and the activated part. <P>SOLUTION: Execution timing of a shut down trigger is basically by a timer based on predetermined power non-supply state transition time t. However, an image processing device has been changed to a sleep mode, it requires time at next starting up. Thereby, average timer setting time is adopted, considering a present antinomic state showing that priority of convenience requires relatively long timer setting time, and priority of a power-saving property requires relatively short timer setting time. A power supply control device mainly uses the timer for timing (the shut down trigger) of transition from a standby mode to the sleep mode; and adjusts the power non-supply state transition time t of the timer based on mobile body detection by a first human detection sensor 28 and a second human detection sensor 30. <P>COPYRIGHT: (C)2012,JPO&INPIT |
