Information processing apparatus and non-transitory computer readable medium for exiting a power saving state based on detection of a target
An information processing apparatus includes plural detectors and a transition unit. The plural detectors detect a person and have different detection areas. The transition unit makes a transition from a power saving state to a normal state if a return condition that the person is detected by a predetermined detector among the plural detectors is satisfied, the power saving state being a state in which power lower than usual power is supplied, the normal state being a state in which the usual power is supplied. The transition unit sets, as the return condition, a condition that an intention of using the information processing apparatus by the person is detected and a detector, among the plural detectors, having a detection area wider than a detection area of the predetermined detector detects the person.
1. An information processing apparatus comprising:
a first detector and a second detector that detect a person, the first detector having a wider detection area than the second detector;
a communication unit that communicates with an external device; and
a processor configured to:
detect whether an intention of using the information processing apparatus by a person exists or not, and in a case where the intention exists, determine whether a predetermined time since detection of the intention has elapsed,
wherein the intention of using the information processing apparatus comprises a state where the external device is entered, by the communication unit, into a state where the external device is paired with the information processing apparatus;
determine whether the first detector has detected the person;
in a case where the first detector has detected the person and the predetermined time since detection of the intention has elapsed, activate the second detector and then change the information processing apparatus from a power saving state to a normal state if the person is detected by the second detector; and
in a case where the first detector has detected the person and the predetermined time since the detection of the intention has not elapsed, change the information processing apparatus from the power saving state to the normal state,
wherein the power saving state is a state whose power consumption is lower than that of the normal state.
2. The information processing apparatus according to claim 1 , wherein the processor is further configured to:
deactivate the second detector if the information processing apparatus is changed to the normal state as a result of detection of the person by the second detector.
3. The information processing apparatus according to claim 1 , wherein
detection of the person by the first detector or the second detector is a return condition for changing the state from the power saving state to the normal state, and
the processor is further configured to:
change the return condition to a condition that the second detector detects the person after completion of a process corresponding to the intention of using the information processing apparatus.
4. The information processing apparatus according to claim 2 , wherein
detection of the person by the first detector or the second detector is a return condition for changing the state from the power saving state to the normal state, and
the processor is further configured to:
change the return condition to a condition that the second detector detects the person after completion of a process corresponding to the intention of using the information processing apparatus.
5. The information processing apparatus according to claim 1 , wherein
the first detector and the second detector have detection areas that are set such that a narrower detection area is encompassed by a wider detection area.
6. The information processing apparatus according to claim 1 , wherein
the intention of using the information processing apparatus comprises a state where the external device displays a specific screen or activates a specific application.
7. The information processing apparatus according to claim 1 , wherein
the intention of using the information processing apparatus comprises a time period during which usage of the image processing apparatus is high.
8. The information processing apparatus according to claim 1 , further comprising:
a memory that temporarily stores data, wherein
the intention of using the information processing apparatus corresponds to an instruction for outputting the data stored in the memory.
9. The information processing apparatus according to claim 1 , wherein
the first detector and the second detector include at least a person sensor or a camera.
10. A non-transitory computer readable medium storing a program causing a computer to execute a process for information processing, the process comprising:
communicating with an external device;
detecting whether an intention of using an information processing apparatus by a person exists or not, and in a case where the intention exists, determining whether a predetermined time since detection of the intention has elapsed,
wherein the intention of using the information processing apparatus comprises a state where the external device is entered into a state where the external device is paired with the information processing apparatus;
determining whether a first detector has detected the person, the first detector having a wider detection area than a second detector;
in a case where the first detector has detected the person and the predetermined time since detection of the intention has elapsed, activating the second detector and then changing the information processing apparatus from a power saving state to a normal state if the person is detected by the second detector; and
in a case where the first detector has detected the person and the predetermined time since the detection of the intention has not elapsed, changing the information processing apparatus from the power saving state to the normal state,
wherein the power saving state is a state whose power consumption is lower than that of the normal state.
