Abstract
Official abstract text for this publication.
A device control system includes a detecting apparatus configured to detect an object in a predetermined space, and an information processing apparatus configured to control an illuminating apparatus based on a detection result of the object. The device control system includes an obtaining unit configured to obtain, from the detecting apparatus, information relating to an illuminance in the predetermined space; and a control unit configured to control, when the illuminance in the predetermined space falls below a first targeted illuminance, the illuminating apparatus so that the illuminance in the predetermined space becomes a second targeted illuminance that is greater than the first illuminance.
First claim
Opening claim text (preview).
What is claimed is: 1. A device control system including a detecting apparatus configured to detect an object in a predetermined space, and an information processing apparatus configured to control an illuminating apparatus based on a detection result of the object, the device control system comprising: an obtaining unit configured to obtain, from the detecting apparatus, information relating to an illuminance in the predetermined space; and a control unit configured to control, when the illuminance in the predetermined space falls below a first targeted illuminance, the illuminating apparatus so that the illuminance in the predetermined space becomes a second targeted illuminance that is greater than the first targeted illuminance, wherein when the illuminance in the predetermined space exceeds the second targeted illuminance for a time longer than a threshold time, the control unit controls the illuminating apparatus so that the illuminance in the predetermined space becomes the second targeted illuminance. 2. The device control system according to claim 1 , wherein, when the illuminance in the predetermined space is in a range from the first targeted illuminance to the second targeted illuminance, the control unit does not control the illuminating apparatus. 3. The device control system according to claim 1 , wherein, when the illuminance in the predetermined space falls below the first targeted illuminance, the control unit controls the illuminating apparatus in a range not exceeding a predetermined maximum light level so that the illuminance in the predetermined space becomes the second targeted illuminance. 4. The device control system according to claim 1 , wherein, when the illuminance in the predetermined space exceeds the second targeted illuminance, the control unit controls the illuminating apparatus in a range not falling below a predetermined lower limit light level so that the illuminance in the predetermined space becomes the second targeted illuminance. 5. The device control system according to claim 1 , wherein when a light level of the illuminating apparatus is set to be a maximum light level in a state in which external light is not present, the illuminance in the predetermined space is the first targeted illuminance. 6. The device control system according to claim 1 , wherein when a light level of the illuminating apparatus is set to be a maximum light level in a state in which external light is not present, the illuminance in the predetermined space is less than the first targeted illuminance. 7. The device control system according to claim 6 , wherein when a light level of the illuminating apparatus is set to be a maximum light level in a state in which external light is not present, the illuminance in the predetermined space is a third targeted illuminance that is less than the first targeted illuminance. 8. The device control system according to claim 1 , wherein a difference between the first targeted illuminance and the second targeted illuminance is determined in consideration of a rapidity of change of external light, an amount of change of the external light within a fixed time, or a change of the illuminance in the predetermined space due to turning off an adjacent illuminating apparatus. 9. The device control system according to claim 1 , wherein, when controlling the illuminating apparatus so that the illuminance in the predetermined space becomes the first targeted illuminance or the second targeted illuminance, the control unit converts the first targeted illuminance or the second targeted illuminance into a light level so that the illuminance in the predetermined space becomes the first targeted illuminance or the second targeted illuminance.
