Title:
FLICKER MEASUREMENT DEVICE AND MEASUREMENT METHOD
Document Type and Number:
WIPO Patent Application WO/2021/090689
Kind Code:
A1
Abstract:
The present invention comprises a detection means (13) that detects candidates for the frequency of a fluctuation in light volume of a measurement subject (100), a frequency determination means (14) that determines the frequency of the fluctuation in light volume on the basis of the detected candidates for the frequency of the fluctuation in light volume, a resolution determination means (15) that determines the frequency resolution of flicker measurement on the basis of the determined frequency of the fluctuation in light volume, and a flicker measurement means (16) that measures flickering using the determined frequency resolution. The resolution determination means (15) determines one integer portion of the frequency of the fluctuation in light volume determined by the frequency determination means (14) as the frequency resolution.
