Abstract

An information processing apparatus according to the present embodiment has, as operation modes, a normal operation power mode and a power-saving mode in which power consumption is lower than that of the normal operation power mode. The apparatus comprises a human detection sensor which is able to detect a user of the information processing apparatus. The apparatus shifts, based on a detection result of the human detection sensor, the operation mode of the information processing apparatus from the second power mode to the first power mode, and determines whether or not to shift the operation mode of the information processing apparatus to the second mode based on a detection result of the human detection sensor when a first predetermined time period has elapsed without receiving a user operation after shifting the operation mode to the first power mode.

First claim

What is claimed is:

1 . An information processing apparatus having, as operation modes, a first power mode and a second power mode in which power consumption is less than that of the first power mode, the apparatus comprising:
a human detection sensor which is able to detect a user of the information processing apparatus; a shift unit configured to, based on a detection result of the human detection sensor, shift the operation mode of the information processing apparatus from the second power mode to the first power mode; and a determination unit configured to determine whether or not to shift the operation mode of the information processing apparatus to the second mode based on a detection result of the human detection sensor when a first predetermined time period has elapsed without receiving a user operation after shifting the operation mode to the first power mode.

2 . The information processing apparatus according to claim 1 , wherein when the operation mode of the information processing apparatus is caused to shift from the second power mode to the first power mode, the shift unit stops supply of power to the human detection sensor, and when the first predetermined time period has elapsed without receiving a user operation after shifting the operation mode to the first power mode, the shift unit causes detection of an object by supplying power to the human detection sensor.

3 . The information processing apparatus according to claim 2 , wherein the shift unit shifts the operation mode of the information processing apparatus from the first power mode to the second power mode in a case where no person is detected by the human detection sensor to which power has been supplied after the first predetermined time period has elapsed without receiving a user operation.

4 . The information processing apparatus according to claim 2 , wherein the shift unit stops power supply to the human detection sensor in a case where a person is detected by the human detection sensor to which power is supplied after the first predetermined time period has elapsed without receiving a user operation, and
the determination unit checks that the first predetermined time period has elapsed again.

5 . The information processing apparatus according to claim 4 , wherein the shift unit shifts the operation mode of the information processing apparatus from the first power mode to the second power mode in a case where an elapsed number of the first predetermined time period exceeds a threshold without receiving a user operation.

6 . The information processing apparatus according to claim 4 , wherein the determination unit issues an alert when an elapsed number of the first predetermined time period reaches a threshold, and
the shift unit shifts the operation mode of the information processing apparatus from the first power mode to the second power mode in a case where the elapsed number of the first predetermined time period exceeds the threshold without receiving a user operation.

7 . The information processing apparatus according to claim 5 , wherein
the determination unit checks that a second predetermined time period has elapsed after executing processing corresponding to user input when the user input is received before the first predetermined time period elapses, and checks that the first predetermined time period has elapsed again when the second predetermined time period has elapsed.

8 . The information processing apparatus according to claim 7 , wherein the determination unit resets the number of timings when checking that the second predetermined time period has elapsed again.

9 . The information processing apparatus according to claim 7 , wherein the determination unit issues an alert when checking that the first predetermined time period has elapsed again, and
the shift unit shifts the operation mode of the information processing apparatus from the first power mode to the second power mode in a case where the first predetermined time period has elapsed again without receiving a user operation.

10 . The information processing apparatus according to claim 6 , wherein the shift unit, by at least one of audio output and display output, notifies, as the alert, that the information processing apparatus will transit into the second power mode in a case where user input is not performed.

11 . The information processing apparatus according to claim 1 , wherein the shift unit, in a case where the operation mode of the information processing apparatus is caused to return from the second power mode to the first power mode, supplies power to only devices necessary for receiving user input thereafter.

12 . The information processing apparatus according to claim 1 , wherein the human detection sensor is an ultrasonic sensor, a pyroelectric sensor, or an infrared array sensor having a fixed detection range.

13 . A method of controlling an information processing apparatus having a human detection sensor which is able to detect a user of the information processing apparatus, and, as operation modes, a first power mode and a second power mode in which power consumption is less than that of the first power mode, the method comprising:
based on a detection result of the human detection sensor, shifting the operation mode of the information processing apparatus from the second power mode to the first power mode, and determining whether or not to shift the operation mode of the information processing apparatus to the second mode based on a detection result of the human detection sensor when a first predetermined time period has elapsed without receiving a user operation after shifting the operation mode to the first power mode.

14 . A computer-readable storage medium storing a computer program for causing a computer to execute each step of a method of controlling an information processing apparatus having a human detection sensor which is able to detect a user of the information processing apparatus, and, as operation modes, a first power mode and a second power mode in which power consumption is less than that of the first power mode, the method comprising:
based on a detection result of the human detection sensor, shifting the operation mode of the information processing apparatus from the second power mode to the first power mode, and determining whether or not to shift the operation mode of the information processing apparatus to the second mode based on a detection result of the human detection sensor when a first predetermined time period has elapsed without receiving a user operation after shifting the operation mode to the first power mode.
