Abstract: The illuminance acquisition device includes a setting unit, a human sensing unit, and an illuminance acquisition unit. The setting unit sets an illuminance acquisition area (as a first area) for use to acquire an illuminance in an image capturing area of an image capturing unit. The human sensing unit determines, based on an image captured by the image capturing unit, whether or not there is any human in a human sensing area (as a second area) of the image capturing area. The illuminance acquisition unit calculates, based on the image, a spatial illuminance in the first area.

Abstract: A control system includes: a first human detector that detects the presence or absence of a human within a first detection range; a second human detector that has a second detection range that overlaps with the first detection range, and detects the presence or absence of a human within the second detection range; a determiner that has a plurality of determination modes for determining the presence or absence of a human; a transmitter that transmits a control signal to a control target based on a result of determination made by the determiner; and a load that receives the control signal and serves as the control target whose operation mode is switched according to the control signal. The determiner performs operation in a first determination mode for determining the presence or absence of a human based on at least a result of detection performed by the first human detector when the load is in a first operation mode, and performs operation in a second determination mode for determining the presence or absence of a human based on a result of detection performed by the second human detector when the load is in a second operation mode that is different from the first operation mode.
