Provided is a novel light adjustment program that can make a human feel at ease. Provided is the light adjustment program that includes the steps of obtaining basic data having 1/f fluctuation characteristics; generating first smoothed data and second smoothed data by performing moving average processing with different periods on the basic data having 1/f fluctuation characteristics; generating light adjustment data by subjecting the first smoothed data and the second smoothed data to arithmetic processing; and changing luminance of a light-emitting device in time series in accordance with the light adjustment data.

Light adjustment program, light-emitting apparatus, and lighting device

The power consumption of a control device or a data processing system is reduced. Safety is enhanced. An electronic device is operated in a simple way. A control device includes an arithmetic circuit, an input unit, and a power management unit. The input unit includes a sensor element. The power management unit has a function of controlling supply and shutdown of power to the arithmetic circuit.
