Patent ID: 8159691

Claim:
An information processing apparatus for managing an image processing apparatus having a processing mode which involves processing related to an image and having a plurality of power control modes which do not involve processing related to the image, wherein the plurality of power control modes include a standby mode, and a low power mode which consumes power that is smaller than power consumed in the standby mode, the information processing apparatus comprising: a specifying unit that specifies user identification information which identifies at least one of a user that uses the image processing apparatus and a department to which the user belongs; a counting unit that counts a page outputting number for the processing mode; a timing unit that times an operation time for each of the plurality of power control modes; a memory unit that stores a power consumption amount per page for the processing mode, and a power consumption amount per unit time for each of the plurality of power control modes; a calculation unit that calculates (i) a power consumption amount of the image processing apparatus for the processing mode by multiplying the power consumption amount per page stored by said memory unit and the page outputting number counted by said counting unit, and (ii) a power consumption amount of the image processing apparatus for the plurality of power control modes by multiplying the power consumption amount per unit time stored by said memory unit and the operation time timed by said timing unit; and a preparation unit that prepares statistical information concerning (i) the power consumption amount of the image processing apparatus for the processing mode calculated by said calculation unit, and (ii) the power consumption amount of the image processing apparatus for the power control mode calculated by said calculation unit, wherein said preparation unit prepares the statistical information concerning the power consumption amount of the processing mode for the specified user identification information specified by said specifying unit and concerning the power consumption amount of the plurality of power control modes such that the power consumption amount of the plurality of power control modes is not associated with any user identification information.
