Patent ID: 7982889

Claim:
An image processing apparatus comprising: a communicating medium that communicates with an external apparatus to at least receive a data processing request indicating one or more of a plurality of image processing related functions to be performed by the image processing apparatus; a plurality of function blocks that are each a part of a group of parts sectionalized in accordance with different image processing related functions that can be requested to be performed by the data processing request; at least one energization switching circuit that is operable to switch power from at least one power source to a plurality of function blocks in order to individually change the state of each of the plurality of function blocks from a non-energized state to an energized state so as to be able to perform an associated image processing related function or functions; and at least one energization controlling unit that controls the at least one energization switching circuit to switch power from the at least one power source to the plurality of function blocks that correspond to the image processing related function or functions to be performed by the image processing apparatus as indicated by contents of the data processing request, the at least one energization controlling unit controlling energization of the at least one energization switching circuit to energize the function blocks that correspond to the image processing related function or functions to be performed by the image processing apparatus as indicated by contents of the data processing request and based on a determination of an existing state of the image processing apparatus.
