Electronic apparatus, control method, and program
An electronic apparatus includes: a system processing unit configured to execute system processing based on a system; a person detection unit configured to detect a change from a first detection state in which a person is present within a predetermined detection range to a second detection state in which no person is present; an operation control unit configured to instruct the system processing unit to cause the operating state of the system to make a transition to a first operating state when the change from the first detection state to the second detection state is detected by the person detection unit; and a prohibition control unit configured to instruct the operation control unit to prohibit the transition to the first operating state when the change from the first detection state to the second detection state is detected by the person detection unit.
1. An electronic apparatus comprising:
a system processing unit configured to execute system processing based on a system;
a person detection unit configured to detect a change from a first detection state in which a person is present within a predetermined detection range to a second detection state in which no person is present within the predetermined detection range;
an operation control unit configured to instruct the system processing unit to cause an operating state of the system to transition to a first operating state in which at least part of the system processing is limited when the change from the first detection state to the second detection state is detected by the person detection unit;
a prohibition control unit configured to instruct the operation control unit to prohibit the transition to the first operating state when the change from the first detection state to the second detection state is detected by the person detection unit, and to cancel prohibition on the transition to the first operating state based on a processing state of a specific processing executed in the system processing; and
the prohibition control unit, after confirming without user intervention that playback of a video by the electronic apparatus has stopped, cancels prohibition on the transition to the first operating state.
2. The electronic apparatus according to claim 1 , further comprising:
a playback processing unit configured to execute video playback processing as the specific processing executed in the system processing; and
a playback control unit configured to instruct the playback processing unit to stop playback of the video when the change from the first detection state to the second detection state is detected by the person detection unit and to prohibit the transition to the first operating state given by the prohibition control unit.
3. The electronic apparatus according to claim 1 , wherein, when the change from the first detection state to the second detection state is detected by the person detection unit, the prohibition control unit instructs the operation control unit to prohibit the transition to the first operating state when the specific processing is in a first processing state, and cancels the prohibition on the transition to the first operating state when the specific processing is changed from the first processing state to a second processing state.
4. The electronic apparatus according to claim 1 , wherein, when the change from the first detection state to the second detection state is detected by the person detection unit, the operation control unit performs control to make at least part of a display image to be displayed on a display unit invisible, and after that, when the prohibition on the transition to the first operating state is canceled by the prohibition control unit, the operation control unit instructs the system processing unit to make the transition to the first operating state.
5. A control method for an electronic apparatus including a system processing unit configured to execute system processing based on a system, the control method comprising:
a person detection step of causing a person detection unit to detect a change from a first detection state in which a person is present within a predetermined detection range to a second detection state in which no person is present within the predetermined detection range;
an operation control step of causing an operation control unit to instruct the system processing unit to cause an operating state of the system to transition to a first operating state in which at least part of the system processing is limited when the change from the first detection state to the second detection state is detected in the person detection step;
a prohibition control step of causing a prohibition control unit to instruct the operation control unit to prohibit the transition to the first operating state when the change from the first detection state to the second detection state is detected by the person detection unit, and to cancel prohibition on the transition to the first operating state based on a processing state of a specific processing executed in the system processing; and
the prohibition control step further including, after confirming without user intervention that playback of a video by the electronic apparatus has stopped, cancels prohibition on the transition to the first operating state.
6. A non-transitory computer readable medium with computer executable instructions stored thereon, executed by a processor, to perform a method to execute system processing based on a system, the method comprising:
a person detection step of detecting a change from a first detection state in which a person is present within a predetermined detection range to a second detection state in which no person is present within the predetermined detection range;
an operation control step of instructing the system processing unit to cause an operating state of the system to make a transition to a first operating state in which at least part of the system processing is limited when the change from the first detection state to the second detection state is detected in the person detection step;
a prohibition control step of giving an instruction to prohibit the transition to the first operating state when the change from the first detection state to the second detection state is detected in the person detection step, and to cancel prohibition on the transition to the first operating state based on a processing state of a specific processing executed in the system processing;
the prohibition control step further including, after confirming without user intervention that playback of a video by the electronic apparatus has stopped, cancels prohibition on the transition to the first operating state.
