Electronic device
An electronic device comprises: a detection unit configured to detect movement of a person; and a control unit configured to, in a case where the detection unit detects a first movement of the person, control an operation unit such that the operation unit is changed from a first state to a second state and maintains the second state for a first predetermined period, wherein, in a case where the detection unit detects a second movement of the person in a predetermined detection period spanning from before an end time of the first predetermined period until after the end time, the control unit controls the operation unit such that the operation unit maintains the second state until an end of a second predetermined period changed from the first predetermined period according to an aspect of the second movement.
1. An electronic device of a lighting system mounted to a ceiling of a toilet booth comprising:
a detection unit configured to detect movement of a person within the toilet booth; wherein when the movement of the person is detected, the lighting system emits light toward the person; and
a control unit configured to, in a case where the detection unit detects a first movement of the person, control an operation unit of the lighting system such that the operation unit is changed from a first state, of not emitting light, to a second state of emitting light, and maintains the second state for a first predetermined period, wherein,
in a case where the detection unit detects a second movement of the person for maintaining the operation unit in the second state, in a predetermined detection period spanning from before an end time of the first predetermined period until after the end time, the control unit controls the operation unit such that the operation unit maintains the second state until an end of a second predetermined period changed from the first predetermined period and directly lasting based on a time aspect of the second movement of the person,
in a case where the first predetermined period ends and the operation unit is changed from the second state to the first state, the control unit determines whether a third predetermined period has elapsed, and
in a case where the detection unit detects the second movement during the third predetermined period, the first state is changed to the second state and the second state is maintained for the second predetermined period.
2. The electronic device according to claim 1 ,
wherein the control unit controls the operation unit in a state of issuing an advance notification that the operation unit returns to the first state from the second state in the predetermined detection period.
3. The electronic device according to claim 1 ,
wherein the predetermined detection period is at least one of a first period before the end time until the end time or a second period from the end time until after the end time.
4. The electronic device according to claim 1 ,
wherein the control unit changes a length of the second predetermined period according to at least one of a count of the second movement or a length of a period during which the second movement continues.
5. The electronic device according to claim 1 ,
wherein the first state is a state where the operation unit is stopped and the second state is a state where the operation unit operates, or the first state is a state where the operation unit operates and the second state is a state where the operation unit is stopped.
