Backlight correction
When strong backlight enters the lens, the lens iris closes accordingly, and the other
objects become dark.
The backlight correction function is provided for this camera. With this function, the signal
level for such a strong backlight is automatically corrected, and the other objects do not
become dark.
When strong light enters the upper half portion of the critical photometric area No.1 with the
photometric area set to No.1, the backlight correction function is activated automatically.
The backlight correction function is activated in any light control mode.
When strong light enters the critical photometric area, effective backlight correction is
performed by selecting a photometric area far from the position of strong light.
If video signal level is not appropriate when the backlight correction function is being
activated, adjust the video signal level.
