Patent ID: 7965399

Claim:
An information processing apparatus for managing an image processing apparatus having a plurality of operation modes including a first operation mode which involves a print output operation, and a second operation mode which does not involve a print output operation, and having a plurality of power control modes which do not involve processing related to an image, wherein the plurality of power control modes include a standby mode, a plurality of low power modes that consume different powers, respectively, and which are smaller than power consumed in the standby mode, and a sleep 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 first operation mode; a timing unit that times an operation time for the second operation mode and 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 first operation mode, a power consumption amount per unit time for the second operation 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 first operation mode by multiplying the power consumption amount per page stored by said memory unit and the page outputting number counted by said counting unit, (ii) a power consumption amount of the image processing apparatus for the second operation mode by multiplying the power consumption amount per unit time stored by said memory unit and the operation time timed by said timing unit, and (iii) a power consumption amount of the image processing apparatus for the plurality of power control modes; and a preparation unit that prepares statistical information concerning (i) the power consumption amount of the image processing apparatus for the first operation mode calculated by said calculation unit, (ii) the power consumption amount of the image processing apparatus for the second operation mode calculated by said calculation unit, and (iii) the power consumption amount of the image processing apparatus for the power control mode calculated by said calculation unit, wherein said calculation unit calculates a power consumption amount of the image processing apparatus for the specified user identification information specified by said specifying unit, and wherein said preparation unit prepares statistical information concerning the power consumption amount of the image processing apparatus for the specified user identification information, and does not associate the power consumption amount of the image processing apparatus for the plurality of power control modes with the specified user identification information.
