Abstract
An individual ECU (luminance adjustment apparatus) adjusts a luminance value of a lamp. The individual ECU adjusts the luminance value of the lamp according to a luminance pattern in which luminance values are indicated in keeping with elapsed time in one cycle. The individual ECU acquires a synchronization count value (or “time value”) relating to the luminance pattern and changes an adjustment count value (or “actual value”) of the elapsed time in one cycle based on the acquired synchronization count value.
Claims14
A luminance adjustment apparatus that adjusts a luminance value of a lamp, comprising:
- a processing unit configured to execute a process,
- wherein the processing unit:
- adjusts the luminance value of the lamp according to a luminance pattern in which luminance values are indicated in keeping with elapsed time in one cycle;
- acquires a time value relating to the luminance pattern;
- and
- changes an actual value of the elapsed time based on the acquired time value.
A luminance adjustment system comprising:
- a plurality of luminance adjustment apparatuses configured to adjust luminance values of lamps;
- and
- a transmission apparatus configured to transmit a time value, which relates to a luminance pattern in which luminance values are indicated in keeping with elapsed time in one cycle, to the plurality of luminance adjustment apparatuses,
- wherein each luminance adjustment apparatus includes a processing unit configured to execute processing, and
- the processing unit in each luminance adjustment apparatus:
- adjusts the luminance value of lamps corresponding to the luminance adjustment apparatus out of the plurality of lamps according to the luminance pattern;
- acquires the time value transmitted by the transmission apparatus;
- and
- changes an actual value of the elapsed time based on the acquired time value.
A luminance adjustment method of adjusting the luminance of a lamp, causing a computer to execute:
- a step of adjusting the luminance value of the lamp according to a luminance pattern in which luminance values are indicated in keeping with elapsed time in one cycle;
- a step of acquiring a time value relating to the luminance pattern;
- and
- a step of changing an actual value of the elapsed time based on the acquired time value.
