Abstract:
1. An information-processing apparatus having a first operation mode, a second operation mode having power consumption smaller than the first operation mode, and a third operation mode having power consumption smaller than the second operation mode, comprising: an image processing unit configured to carry out image processing; a determination unit configured to determine whether or not the image processing unit is operating; and a control unit configured to control changeover between the first to third operation modes based on a determination result by the determination unit so that a system is shifted to the first operation mode if the image processing unit is operating while being shifted to the second operation mode if it is not operating, and the system is shifted to the first operation mode if the image processing unit starts the operation while being shifted to the second operation mode if other units excepting the image processing unit start the operation, during the third operation mode.
