Backlight Compensation (BLC)

If there is excessive light (for example, a window exists in a scene), the camera tries to compensate by reducing the overall exposure, resulting in the areas surrounding the window becoming too dark. Turn the BLC switch ON to eliminate the silhouette effect.

Flickerless Mode (FL)

Set the FL switch to ON to remove the flicker in a picture. For PAL models, the shutter speed is 1/100 second; for NTSC models, the shutter speed is 1/120 second.

Automatic Gain Control (AGC)

This feature can improve picture quality when the level of scene illumination is low. When set to OFF, the gain is 11 dB. When set to ON, the gain is 30 dB.

Auto White Balance (AWB)
