Abstract

An information processing apparatus capable of communicating with an external device includes a receiving unit configured to receive from the external device a shutdown instruction for shutting down the information processing apparatus, a detection unit configured to detect a person being present near the information processing apparatus, and a control unit configured to restrict shutdown of the information processing apparatus according to the shutdown instruction received by the receiving unit while the detection unit is detecting presence of a person near the information processing apparatus.

Claims

1. An information processing apparatus capable of communicating with an external device, the information processing apparatus comprising:

a detection unit configured to detect a person being present near the information processing apparatus;

a transmission unit configured to, if the detection unit detects a person near the information processing apparatus, transmit a screen for selecting on the external device whether to forcibly shut down the information processing apparatus or to wait shutdown of the information processing apparatus; and

a control unit configured to shut down the information processing apparatus if an instruction for forcibly shutting down the information processing apparatus has been issued on the screen displayed on the external device, and if an instruction for waiting shutdown of the information processing apparatus has been issued on the screen displayed on the external device, to restrict the shutdown until the detection unit no longer detects a person near the information processing apparatus.

2. The information processing apparatus according to claim 1, wherein the detection unit includes a sensor configured to detect presence of a person by receiving infrared rays radiated from the person.

3. The information processing apparatus according to claim 1, wherein the control unit is configured to execute shutdown of the information processing apparatus when the detection unit no longer detects the person who had been present near the information processing apparatus.

4. The information processing apparatus according to claim 1, wherein the control unit is configured to, if the instruction for forcibly shutting down the information processing apparatus has been issued on the screen, shut down the information processing apparatus according to the instruction even if the detection unit detects that a person is present near the information processing apparatus.

5. The information processing apparatus according to claim 1, wherein the transmission unit is configured to transmit to the external device information indicating presence or absence of a person near the information processing apparatus.

6. The information processing apparatus according to claim 1, further comprising a display unit configured to, if shutdown of the information processing apparatus is executed, display a screen indicating that the shutdown is being executed.

7. The information processing apparatus according to claim 1, wherein the shutdown includes processing for stopping power supply to the information processing apparatus.

8. A method for controlling an information processing apparatus that is capable of communicating with an external device, the method comprising:

detecting a person being present near the information processing apparatus;

transmitting, if it is detected that a person is present near the information processing apparatus, to the external device a screen for selecting whether to forcibly shut down the information processing apparatus or to wait shutdown of the information processing apparatus; and

performing control to shut down the information processing apparatus if an instruction for forcibly shutting down the information processing apparatus has been issued on the screen displayed on the external device, and if an instruction for waiting shutdown of the information processing apparatus has been issued on the screen displayed on the external device, to restrict the shutdown until a person near the information processing apparatus is no longer detected.

9. A recording medium on which a program is recorded, wherein the program causes a computer in an information processing apparatus capable of communicating with an external device to function as:

a detection unit configured to detect a person being present near the information processing apparatus;

a transmission unit configured to, if the detection unit detects a person near the information processing apparatus, transmit a screen for selecting on the external device whether to forcibly shut down the information processing apparatus or to wait shutdown of the information processing apparatus; and

a control unit configured to shut down the information processing apparatus if an instruction for forcibly shutting down the information processing apparatus has been issued on the screen displayed on the external device, and if an instruction for waiting shutdown of the information processing apparatus has been issued on the screen displayed on the external device, to restrict the shutdown until the detection unit no longer detects a person near the information processing apparatus.

10. An information processing apparatus capable of communicating with an external device, the information processing apparatus comprising:

a receiving unit configured to receive from the external device a shutdown instruction for shutting down the information processing apparatus;

a detection unit configured to detect a person being present near the information processing apparatus; and

a control unit configured to restrict shutdown of the information processing apparatus according to the shutdown instruction received by the receiving unit while the detection unit is detecting presence of a person near the information processing apparatus.

11. The information processing apparatus according to claim 10, wherein the detection unit includes a sensor configured to detect presence of a person by receiving infrared rays radiated from the person.

12. The information processing apparatus according to claim 10, wherein the control unit is configured to execute shutdown of the information processing apparatus when the detection unit no longer detects the person who had been present near the information processing apparatus.

13. The information processing apparatus according to claim 10, further comprising a transmission unit configured to transmit to the external device information indicating presence or absence of a person near the information processing apparatus.

14. The information processing apparatus according to claim 10, further comprising a display unit configured to, if shutdown of the information processing apparatus is executed, display a screen indicating that the shutdown is being executed.

15. The information processing apparatus according to claim 10, wherein the shutdown includes processing for stopping power supply to the information processing apparatus.

16. A method for controlling an information processing apparatus capable of communicating with an external device, the method comprising:

receiving from the external device a shutdown instruction for shutting down the information processing apparatus;

detecting a person being present near the information processing apparatus; and

performing control to restrict shutdown of the information processing apparatus according to the received shutdown instruction while presence of a person near the information processing apparatus is being detected.

17. A recording medium on which a program is recorded, wherein the program causes a computer in an information processing apparatus capable of communicating with an external device to function as:

a receiving unit configured to receive from the external device a shutdown instruction for shutting down the information processing apparatus;

a detection unit configured to detect a person being present near the information processing apparatus; and

a control unit configured to restrict shutdown of the information processing apparatus according to the shutdown instruction received by the receiving unit while the detection unit is detecting presence of a person near the information processing apparatus.
