Abstract
An information processing apparatus including a volatile storage unit, and is operated in any of a plurality of modes including a first power mode and a second power mode, power being supplied to the storage unit in the first power mode and the second power mode, power consumption in the first power mode being higher than power consumption in the second power mode.
Claims18
An image processing apparatus comprising:
- a display;
- one or more controllers, each including a processor, a first memory configured to store program data to be executed by the processor, and a second memory configured to hold working data loaded from the program data;
- and
- a power source unit capable of operating in a plurality of power supply states, the plurality of power supply states including (A) a power-saving state in which the power to the processor is stopped and the power is supplied to the second memory, and (B) a power-on state in which the power is supplied to the processor and the second memory,
- wherein the one or more controllers are configured to function as:
- a first unit configured to cause the second memory to hold the working data including information about a screen to be currently displayed, and cause the display to display the screen based on the information about the screen held by the second memory;
- and
- a second unit configured to update the information about the screen to be currently displayed to information about a predetermined screen in the second memory before the power supply state of the power source unit is shifted to the power-saving state so that a screen to be displayed immediately after the power supply state returns to the power-on state next time is the predetermined screen, in response to reception of an instruction to shift the power supply state of the power source unit from the power-on state to the power-saving state.

- one or more controllers, each including a processor, a first memory configured to store program data to be executed by the processor, and a second memory configured to hold working data loaded from the program data;
- and
- a power source unit capable of operating in a plurality of power supply states, the plurality of power supply states includes (A) a power-saving state for a suspend function in which the power to the processor is stopped and the power is supplied to the second memory, and (B) a power-on state in which the power is supplied to the processor and the second memory,
- wherein the one or more controllers are configured to function as:
- a first unit configured to cause the second memory to hold the working data including information about a screen to be currently displayed and cause the display to display the screen based on the information about the screen held by the second memory;
- and
- a second unit configured to shift the power supply state of the power source unit to the power-saving state in response to reception of an instruction to shift the power supply state of the power source unit from the power-on state to the power-saving state, and subsequently, to update the information about the screen to be currently displayed to information about a predetermined screen in the second memory and then turn on the display in response to return to the power-on state.
