1. An image processing apparatus comprising:
- a plurality of devices for realizing a plurality of functions of the image processing apparatus;
a plurality of device control units, each specific device control unit of the plurality of device control units being associated with a specific corresponding device of the plurality of devices to control a power status of the specific corresponding device according to a relevant power mode; and
a power mode setting unit configured to set the relevant power mode to the specific device control unit,wherein a power status corresponding to the power mode set by the power mode setting unit is variable for the plurality of devices, depending on the specific device,wherein the power mode set by the power mode setting unit is selected from a group including low power mode, sleep mode, power on mode and power off mode, and in at least one instance, is the low power mode, andwherein in at least one instance, the specific device control unit determines, in response to the power mode being set to the power off mode by the power mode setting unit while the corresponding device controlled by the specific device control unit is in the power on mode, that the power off mode is not consistent with current operations of the device, and sets the device to the low power mode and not to the power off mode.

15. A power control method for controlling power of an image processing apparatus that includes a plurality of devices for realizing a plurality of functions of the image processing apparatus, and a plurality of device control units, each specific device control unit of the plurality of device control units being associated with a specific corresponding device of the plurality of devices, the method comprising:
-
a device controlling step for controlling, by said each specific device control unit of the plurality of device control units, a power status of the specific corresponding device associated with the specific device control unit, according to a relevant power mode of the image processing apparatus; and a power mode setting step for setting the relevant power mode to the specific device control unit, wherein a power status corresponding to the power mode set in the power mode setting step is variable for the plurality of devices, depending on the specific device, and wherein the power mode set in the power mode setting step is selected from a group including low power mode, sleep mode, power on mode and power off mode, and in at least one instance, is the low power mode, and wherein in at least one instance, the specific device control unit determines, in response to the power mode being set to the power off mode in the power mode setting step while the corresponding device controlled by the specific device control unit is in the power on mode, that the power off mode is not consistent with current operations of the device, and sets the device to the low power mode and not to the power off mode. - View Dependent Claims (16, 17, 18, 19)
