Image processing apparatus having a selectable power-saving mode, and image processing method using the selectable power-saving mode

摘要

An image processing apparatus includes a connection unit that is connected to an external storage device, an image reading unit that reads image data to be stored on the external storage device at least, a controller that controls power to be supplied to the image reading unit by selecting between a standard mode and a power-saving mode consuming power less than in the standard mode. When the external storage device is connecting to the connection unit while the power-saving mode is selected, the controller determines whether the external storage device is enable to be written or not. The controller supplies power to the image reading unit in the standard mode if the controller determines the external storage device is enable to be written, or supplies power to the image reading unit in the power-saving mode if the controller determines the external storage device is not enable to be written.
