permissible exposure limitとは 意味・読み方・使い方

Further, the system control unit 50 calculates a face correction value by adding a value corresponding to the difference between the luminance of the sky area and a permissible luminance upper-limit value of the sky area to a difference between the luminance of the face area and a luminance target value of the face area, and controls exposure based upon a value corresponding to the face correction value.例文帳に追加

また、システム制御部５０は、空領域の輝度と空領域の許容輝度上限値の差分に応じた値を、顔領域の輝度と顔領域の輝度目標値の差分に加えることで、顔補正値を算出し、この顔補正値に応じた値に基づき露出を制御する。 - 特許庁
