BLC (BACK LIGHT COMPENSATION) is useful where a camera
is shooting from indoor to outside such as door gate or lobby
when the background behind the object is very bright.
BLC compensates the brightness of the object in the BLC
window regardless of other area's saturation.
Descriptions
GAIN is the value how much the object's brightness compensates.
Higher GAIN compensates the object brighter but other area becomes saturated
and noise increases.
BLC may not be perfect if the background is varying continuously in bright and
dark.
Sets the location and size of window.
Too small size of window makes the compensation unstable and results in exces-
sive compensation.
Too big size of window results in less compensation.
Position and size can be set if pressed at EXPOSURE > BACKLIGHT > BLC >
AREA.
BLC window has 5x8 blocks and its size and position can be set by a unit of row
and column.
