Abstract

An information processing apparatus which is capable of properly supplying power to an image processing unit and an image output unit from respective different power supplies without using a control instruction. The image processing unit obtains data from an external apparatus. A type of the obtained data is determined, and supply of power to the image processing unit and the image output unit is controlled based on the determined type of the data.

First claim

What is claimed is:

1. An image processing apparatus excluding a printing apparatus for printing an image, the image processing apparatus comprising:
a power supply unit that receives alternating current (AC) power, the power supply unit being different from another power supply unit included in the printing apparatus such that power states of the image processing apparatus are controlled independent of power states of the printing apparatus;
a first network interface that connects the image processing apparatus to and communicates with an external apparatus but not the printing apparatus via a first network not including the printing apparatus, the first network interface capable of receiving data from the external apparatus even when the image processing apparatus is in a first power state in which the power supply unit supplies power to a first part including less than all devices that constitute the image processing apparatus;
a second network interface that connects the image processing apparatus to and communicates with the printing apparatus but not the external apparatus via a second network separate from the first network;
a memory that stores programs; and
a processor that executes the programs stored in the memory to:
shift the image processing apparatus to the first power state;
while not shifting the image processing apparatus from the first power state, determine a type of the data received via the first network interface when the image processing apparatus is in the first power state;
in a case where it is determined that the data received from the external apparatus by the first network interface when the image processing apparatus is in the first power state is a first type data which can be responded without shifting the image processing apparatus from the first power state, respond to the data received via the first network interface without shifting the image processing apparatus from the first power state; and
in a case where it is determined that the data received from the external apparatus by the first network interface when the image processing apparatus is in the first power state is a second type data which is necessary to be transferred to the printing apparatus via the second network interface, shift the image processing apparatus from the first power state to a second power state in which the power supply unit supplies power to the first part including less than all devices that constitute the image processing apparatus and to another device, which is also included in the image processing apparatus, to transfer the received data to the printing apparatus,

wherein in a case where the data received from the external apparatus by the first network interface when the image processing apparatus is in the first power state is the second type data, the image processing apparatus transfers the received second type data to the printing apparatus via the second network interface after shifting from the first power state to the second power state.

2. The image-processing apparatus of claim 1 , wherein, in the case where the data received from the external apparatus by the first network interface when the image processing apparatus is in the first power state is the first type data, the image processing apparatus responds to the external apparatus based on a result of processing the received first type data, without shifting the image processing apparatus from the first power state.

3. The image-processing apparatus of claim 1 , wherein the processor further executes the programs stored in the memory to determine a type of the data received via the first network interface when the image processing apparatus is in the first power state by analyzing the subject received data without shifting the image processing apparatus from the first power state.

4. The image-processing apparatus of claim 1 , wherein the processor further executes the programs stored in the memory to respond to the data received from the external apparatus without performing any inquiry to the printing apparatus.

5. The image-processing apparatus of claim 1 , wherein the processor further executes the programs stored in the memory to transfer the data received from the external apparatus to the printing apparatus even when the printing apparatus is in a state where power is supplied only to the first part including less than all devices that constitute the printing apparatus.

6. The image-processing apparatus of claim 1 , wherein the another device included in the image processing apparatus is not the printing apparatus.

7. A data processing method implemented by an image processing apparatus which excludes a printing apparatus for printing an image and which has a power supply unit that receives alternating current (AC) power, the power supply unit being different from another power supply unit included in the printing apparatus, a first network interface for connecting the image processing apparatus with an external information processing apparatus but not the printing apparatus, and a second network interface for connecting the image processing apparatus with the printing apparatus but not the external information processing apparatus, the data processing method comprising:
shifting the image processing apparatus to a first power state in which the power supply unit supplies power to a first part including less than all devices that constitute the image processing apparatus such that power states of the image processing apparatus are controlled independent of power states of the printing apparatus;
when the image processing apparatus is in the first power state, receiving data from the external information processing apparatus via the first network interface;
while not shifting the image processing apparatus from the first power state, determining a type of the data received via the first network interface when the image processing apparatus is in the first power state;
in a case where it is determined that the type of the data received via the first network interface when the image processing apparatus is in the first power state is a type which can be responded without shifting the image processing apparatus from the first power state, responding to the data received from the external information processing apparatus via the first network interface without shifting the image processing apparatus from the first power state; and
in a case where it is determined that the type of the data received via the first network interface when the image processing apparatus is in the first power state is a type which is necessary to be transferred to the printing apparatus via the second network interface, shifting the image processing apparatus from the first power state to a second power state in which the power supply unit supplies power to the first part including less than all devices that constitute the image processing apparatus and to another device included in the image processing apparatus, and then transferring, to the printing apparatus, the data received via the first network interface when the image processing apparatus is in the first power state.

8. The data processing method of claim 7 , further comprising determining a type of the data received via the first network interface when the image processing apparatus is in the first power state by analyzing the subject received data without shifting the image processing apparatus from the first power state.

9. The data processing method of claim 7 , further comprising responding to the data received from the external information processing apparatus without performing any inquiry to the printing apparatus.

10. The data processing method of claim 7 , further comprising transferrin
