<p><P>PROBLEM TO BE SOLVED: To provide an image processing apparatus such as a multifunction peripheral, duplicating device, computer or the like for efficiently reducing power supply consumption. <P>SOLUTION: In an image processing apparatus 1, ON/OFF of a commercial power supply 20 is controlled by a switching element 6, an internal power at a voltage level based on an ON/OFF control value is generated and supplied to various electrical components by a power supply control section 10, a plurality of operational environment factors relating to an operational environment of the image processing apparatus 1 are detected, an operational status corresponding voltage level tolerance corresponding to an operational status of the image processing apparatus 1 is calculated from an operational environment factor-voltage level tolerance table, in which a plurality of factor values for each operational environment factor and a voltage level tolerance are associated with, a request voltage level is calculated on the basis of a setting voltage level corresponding to a lower limit voltage level tolerance and the operational status corresponding voltage level tolerance, and the ON/OFF control value of the switching element 6 required for generating a voltage of the request voltage level by the power supply control section 10 is determined. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
