Image processing apparatus and method for interrupting a power supply in response to a user's operation or a kernel of the operating system to switch the power supply between a supply of power and an interruption of power to the apparatus, when a time lapse since an interrupt request notification was sent, exceeds one of a plurality of predetermined times

摘要

An image processing apparatus includes: a switch of a main power supply unit that is switched between ON and OFF in response to a user's operation so as to switch the power supply between a supply of power and an interruption of the supply; a first notification unit that sends an interrupt request notification for requesting to interrupt a process in a recoverable way to all of or a part of the applications being run if the switch of a main power supply unit is turned off; and a power supply control unit that interrupts the supply from the power supply when a time lapse, that is measured since a time when the notification unit has sent the interrupt request notification, exceeds a first predetermined time.
