NOTE: 1.
2.The image becomes brighter when the setting increases; however, the after image increases as well. Due to the increased light sensitivity of the Super HAD II chip, far less DSP ‘boost’ is needed, resulting in color or B/W images in low light with minimal ghosting.
3.Please note that spots and noise may appear if light amplification increases when
3.3.3.4BLC-BACKLIGHT COMPENSATION
There are three choices for the type of BLC which may be employed: OFF, traditional BLC or HSBLC.
BLC
Video gain can be adjusted automatically to correct the exposure of subjects that are in front of a bright light source.

| Press “END” to save all the menu settings and exit. |
HSBLC
HSBLC (Highlight Suppression BLC) is used to reduce the brightness of light sources in a specific area. It is activated only in a low illumination environment to minimize the effects of glare from bright lights such as spotlights, street lights or headlights in the field of view. Where ‘traditional’ BLC can increase the exposure of a dark area surrounded by a brighter area, HSBLC can decrease the exposure of bright areas surrounded by darker areas.
