Abstract
A luminance characteristics generation method includes: determining, for each of frames included in a video, a value as first luminance characteristics, the value being obtained by dividing the number of pixels having luminances less than or equal to a first luminance among all pixels included in the frame by the number of all the pixels included in the frame; and outputting the first luminance characteristics determined in the determining of the value.
