(P50 to A50) The ratio of AUTO IRIS/AUTO GAIN up/AUTO ND (ELC)
detected peak to average can be adjusted within a predetermined range.
Iris Area
A photometric measurement method can be selected for AUTO IRIS/AUTO
GAIN UP/AUTO ND (ELC).
ALL: All the screen area is measured.
Center: The screen is measured mainly in the center area, about
