发明名称 Image processing including hibernation
摘要 When the first time has elapsed after the operator operates a power switch to stop power supply, an image processing apparatus forcibly stops power supply. When stopping power supply, the image processing apparatus executes hibernation processing to retract, in a secondary storage device, the stored content of a main memory used as a work area by a CPU. When the hibernation processing will be completed within a target time necessary to complete the hibernation processing and end processing of the image processing apparatus before the first time elapses, the image processing apparatus executes the end processing of the image processing apparatus and stops power supply after completing the hibernation processing; otherwise, the image processing apparatus interrupts the hibernation processing, executes the end processing of the image processing apparatus, and stops power supply.

主权项 1. An image processing apparatus, comprising: a power switch; a power stopping unit that forcibly stops power supply to the image processing apparatus when a first time has elapsed after the power switch is operated; a processing unit that executes hibernation processing to retract, in a second storage unit, a stored content of a first storage unit used as a work area by a CPU of the image processing apparatus in a case where the power switch is operated; a determination unit that determines, after starting the hibernation processing, whether or not the hibernation processing by said processing unit will be completed before the first time elapses; and a control unit that, in a case where the determination unit has determined that the hibernation processing is not completed before the first time elapses, interrupts the hibernation processing being executed by said processing unit, and executes a shutdown processing of the image processing apparatus.
