<P>PROBLEM TO BE SOLVED: To provide an image processing device capable of changing a power supply state of its own device by more minutely corresponding to power supply states of terminal devices. <P>SOLUTION: A sub-CPU 21 of an image processing device 10 inquires at terminal devices 30 connected to a network about their power supply states, and each terminal device sends back power supply state information indicating that its own device is in a normal state, a sleep state, or a shut-down state. Based on the number of terminals in each power supply state obtained by tallying up the response from each terminal device, the image processing device 10 estimates the availability of its own device from the terminal devices to control the power supply state of its own device. <P>COPYRIGHT: (C)2012,JPO&INPIT |
