Abstract
An image processing apparatus includes an image-data processor, an interface, a power source, and a controller. The controller selects a first mode, a second mode, or a third mode as a power supply mode. In the first mode, electric power is supplied from the power source to the image-data processor and the interface. In the second mode, supply of the electric power from the power source to the image-data processor and the interface is in a stopped state. In the third mode, the electric power is supplied from the power source to the interface, but supply of the electric power to the image-data processor is in a stopped state. The controller switches the power supply mode from the second mode to the third mode in response to receiving a power supply request from an external device via the interface in the second mode.
