luminance difference thresholdとは 意味・読み方・使い方

Specifically, the determination is based on the area in the frequency distribution where the luminance difference is not higher than a predetermined threshold and on the ratio of the geometric mean of luminance differences to the arithmetic mean thereof in the frequency distribution where the luminance difference exceeds the predetermined threshold, and the determination result is output (S130).例文帳に追加
