■ SHUTTER

When capturing a subject, moving fast or under low light condition, user can adjust the shutter speed to faster or

slower to get improved images.

ESC : Shutter speed is controlled automatically according to the brightness on the screen.

MANUAL : Shutter speed is controlled in 1/20000 ~ X128 manually.

A.FLK : Use this mode when the screen flickers due to the inconsistent frequency under surrounding lights.

■ SHUTTER MANUAL

■ AGC

Auto Gain Control is to brighten the screen under the low light condition.

■ SSNR ( DIGITAL NOISE REDUCTION )

Noise is lessened under the low light condition.

OFF : Noise reduction has no effect.

LOW: Noise reduction effect is small but there is little afterimage.

MID: Noise reduction effect generally goes proper and afterimage is not strong.

HIGH: Noise reduction effect is excellent but afterimage is also strong.

■ DSS

By controlling Electronic Shutter, it makes the screen brightened under the low light condition.

However, if user sets higher ratio of DSS, afterimage becomes stronger and Auto Focus may not work.

1. If possible, do not use A.FLK and WDR mode at the same time.

2. In internal synchronization system, if SHUTTER is set to ESC and the camera faces to sunlight or strong light

reflecting areas directly, the screen goes wrong. In this case, change the location of the camera.
