摘要

A control unit of the invention controls shifting of an image processing apparatus from an operation state to a standby state with a use frequency information management table, a monitoring unit and a threshold value storage unit that stores a threshold value serving as a determination criterion for shifting the image processing apparatus from the operation state to the standby state. The control unit identifies terminal apparatuses that are connected to a communication line by the monitoring unit, and obtains the use frequency information for all terminal apparatuses that have been identified to be in the connected state from the use frequency information management table and adds the obtained use frequency information, and if a total value obtained by the addition is smaller than the threshold value stored in the threshold value storage unit, outputs a signal instructing the image processing apparatus to shift to the standby state to the image processing apparatus, and if the total value is larger than or equal to the threshold value, outputs a signal instructing the image processing apparatus to maintain the operation state to the image processing apparatus.
