[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.
