[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.
