6. BACK LIGHT SETUP
◆ USER BLC : Enables a user to select a desired area on a picture and
view that area more clearly.
◆ HLC (High Light Compensation) : If the scene contains extremely bright
light areas such as from car headlight, the light can mask out much
of the on-screen detail. Use HLC feature to remove these
exceptionally bright light areas to allow detail such as car license
plate number to become visible.
☞ NOTE
■ Because there can be a difference in the effectiveness of HLC according to the
amount of light area in the screen, optimize the installation angle for the best HLC
performance.
■ When dark, the HLC is only activated when a bright light exceeding a specific
size in NIGHT ONLY mode.
■ The HLC is not activated in day light or when bright light is not present at night
in NIGHT ONLY mode.
■ BLC Function doesn't work in the B/W mode of the DAY/NIGHT menu.
7. SPECO DNR SETUP
This function reduces the background noise in a low light environment.
☞ NOTE
■ When the AGC mode of the EXPOSURE menu is 'OFF', you cannot set the
SPECO DNR to 'ON' or 'OFF'.
■ When adjusting the noise reduction level in DNR3 mode, remember that the
higher level is set, the greater reduction in noise level, as will the brightness of
the image.
