Embodiment approach

[0022] figure 1 is a block diagram of the image processing apparatus 100 of the first exemplary embodiment. The image processing apparatus 100 includes an image reading unit 10, an image forming unit 12, a network interface (I / F) 14, an operation unit 16, a display unit 18, a connection unit 20, a central processing unit (CPU) 22, a memory 24, a storage unit 26 and power supply 30. These hardware components are interconnected via a data bus 22 . The components are powered by a power supply 30 . The CPU 22 , the memory 24 and the storage unit 26 function as a controller 28 that controls the image processing apparatus 100 .

[0023] The image reading unit 10 reads (scans) an image formed on a predetermined medium such as paper. For example, the image reading unit 10 may be an optical scanner. The image read by the image reading unit 10 is stored on the storage unit 26 as image data.

[0024] The image forming unit 12 forms (prints) an image on a predetermined medium such a...

Abstract

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.

Description

technical field [0001] The present invention relates to an image processing device and an image processing method. Background technique [0002] One type of known image processing apparatus has an image forming function for printing an image on a medium such as a paper medium, and an image reading function for scanning the image printed on the paper medium. Another type of known image processing device is provided with a port connectable to an external storage device such as a Universal Serial Bus (USB) memory, prints image data stored on the USB memory, and stores the scanned image. on the USB memory. [0003] Another type of known image processing device operates switchably between a standard mode and a power saving mode to thereby reduce consumed power. Japanese Unexamined Patent Application Publication No. 2008-134765 describes a process of releasing the power saving mode and returning to the standard mode when connection of USB is detected. With this technique, the p...
