Title:
LIGHTING CONTROL DEVICE, METHOD, AND SYSTEM, AND COMPUTER-READABLE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2020/170914
Kind Code:
A1
Abstract:
The present invention prevents strong light from shining on an approaching subject. A lighting device (300) emits light toward a moving subject. A control device (500) controls the light emitted from the lighting device (300) such that the amount of light shining on the subject remains a fixed amount or less. For example, in cases in which the lighting device (300) emits light in pulses, the control device (500) may control the amount of light shining on the subject by controlling at least one from among the pulse width and the pulse strength of the light. The control device (500) may, for example, control the light emitted from the lighting device (300) in accordance with the distance between the lighting device (300) and the subject.
