[7] Backlight Compensation
Multi-Area Light Measuring
⁃
This automatically detects the subject area, the
backlight conditions, and automatically corrects the
backlight.
The following settings configure sensitivity and the
effectiveness of corrections when there is backlight.
・
BLC Weight
The sensitivity to backlight can be configured to a
range of 0 to 15.
Larger values increase the sensitivity to backlight.
・
BLC Bright
The target brightness value of the subject area
when there is backlight can be configured to a
range of 0 to 15.
Larger values increase the effectiveness of the
correction.
Center-weighted metering
⁃
The 48 total areas are divided into 5 and brightness
levels are corrected by weighting and calculating
each area.
The weight of each area can be configured to a
range of 0 to 7. (CENTER is fixed at 7.)
The CENTER position and size can be changed
according to the position of the subject.
BLC Mask
⁃
By specifying masked areas within the 48 total
areas, brightness information of the masked areas
is ignored and brightness levels are corrected.
Note: When the Day/Night switch control is set to
AUTO mode, the backlight cannot be corrected
with multi-area light measuring when the
camera is set to B/W.
