Abstract:
1. An image processing apparatus comprising: a main controller which is coupled to and controls a sub controller; a power supply which is coupled to the main controller and supplies power to the main controller; and a switching unit which is coupled to the power supply and the main controller and selectively allows the power to be supplied from the power supply to the main controller; wherein the sub controller is coupled to the switching unit and determines whether a first power-off event occurs based on an input signal, and controls the switching unit to cut off the power supplied to the main controller if the sub controller determines that the first power-off event occurs, the main controller determines whether a second power-off event different from the first power-off event occurs, and the switching unit cuts off the power supplied to the main controller if the second power-off event occurs, the second power-off event comprises a soft power-off state entered by the image processing apparatus when a predetermined time lapses, and the main controller remains powered-off after the power supplied to the main controller is cut off in the first power-off event and in the second power-off event.
