HLC (Highlight Compensation) Setup
When a strong light such as streetlamp or headlight faces forward to the camera, you can
mask that exposed area in order to protect it from being saturated.
1. Select <Backlight>.
2. Set <Mode> to <HLC>.
3. Select each item and set it properly.
• HLC Mode : Set the HLC mode.
• HLC level : Adjust the brightness
level so as to remove the incoming
highlight from a specific condition.
• Mask tone : Adjust the mask tone of
the highlighted area.
• Mask Color : Specify the masking
color.
• BLC/HLC Box Mode : Specify the
mode of BLC or HLC Box.
M
At night operation, this function will be activated only if the incoming highlight exceeds a certain
area in a low contrast environment.
At night, HLC will not function if the scene is either too bright or too dark.
J
If the shutter mode is set to Manual or A.FLK, the WDR mode will be disabled.
If you select WDR, you may encounter the following problems. So set it to Not Used.
Unnatural change of colors that cause an unnatural image on the screen
-
Noise on the bright area of the image

As the performance of the WDR function may differ depending on the bright-area size of the
image, it is recommended to optimize the installation angle for the best performance.
At night operation, this function will be activated only if the incoming highlight exceeds a certain
area in a low contrast environment.
Increasing the maximum value may cause an unnatural portion of the image.
As long as you use the progressive scanning (VPS), the WDR will not be available because the
CCD read method differs accordingly. If you select to enable VPS, WDR will be set to FIXED
accordingly.
For the best WDR performance, it is recommended to set the IRIS mode to AUTO.
If you select HLC, the auto focus operation may be repeated according to the lighting condition.
So it is recommended to set the focus mode to One shot af or MANUAL.
