Q-See QD6004B 用户手册

This setting allows you to adjust the way the picture is displayed on your screen. Changes 
made will not affect what the camera captures. You can adjust brightness, contrast, 
sharpness, hue and gain with values from 0-255. You can also flip the image horizontally using 
the Mirror setting.

Adaptive Tone-curve Reproduction (ATR) attempts to show details in both the well-lit and 
shaded areas simultaneously for a more complete view. When enabled, both luminance and 
contrast can be adjusted to produce a more balanced image.

The Shutter setting controls how much light is used to “expose” each frame while AGC, or Au-
tomatic Gain Control “amplifies” the image to show more detail. As a general rule, the AUTO 
setting will be sufficient as the camera will automatically adjust to changing light levels.
In the rare situation where automatic settings aren’t ideal, you can chose to adjust the auto-
matic settings or manually set the values by selecting AUTO  or MANUAL respectively. 
Auto Setup
The image at right shows the default settings. 
In this menu, you can adjust how the camera 
behaves in brightly lit or dark situations by 
adjusting the Shutter from 0-255 with zero 
being the darkest. The AGC amplification 
can be turned off or it can be set from x0.25 
to x1.00 but the higher the amplification, the 
higher the “noise” in the image.

Manual Setup
The shutter speed can be set from 1/60 sec-
ond to 1/10,000 second going from lighter 
to darker with the higher speed. AGC’s value 
can range from 6.00 to 44.8. 
If there is a video monitor within the camera’s 
field of view, setting the shutter to 1/100 
(NTSC) or 1/120 (PAL) will reduce the flicker 
on the screen.

There are seven modes available for determining how your camera processes and displays 
color:
ATW - Automatic Tracking White Balance. This is the default the camera constantly analy-
ses and adjusts to create a neutral white balance. Colors may be slightly underexposed but 
generally accurate. Several settings can be modified, but the most significant is the Environ-
ment setting which adjusts the white balance 
based on the light source. Daylight generally 
has a bluish tint while indoor lighting will tend 
towards yellow (light bulbs) or green (fluores-
cent).
PUSH - Working in a narrower band of 
lighting - 2300K-10000K - it may over-com-
pensate the white balance if the field of view 
includes a large, single-colored object. However, it is the preferred mode for areas illuminated 
by halogen lights.
USER1 & USER2 - These are user defined modes The blue and red gains can be adjusted.
ANTI CR - (Anti Color Rolling) Reduces color rolling in areas illuminated by fluorescent lights.
MANUAL - Adjust the setting from 0-255 to best suit your personal preference.
PUSH LOCK - Locks in the white balance at its current level. This can be set by holding a 
piece of white paper in front of the camera. Pushing the multi-function button will then estab-
lish the white balance. Use this when the lighting is constantly changing or the area surround-
ing the object under observation is over- or under-lit

This allows the camera to compensate for lighting coming from behind the subject as well as 
bright light sources within the image. Backlight compensation can be left turned off, turned on 
(BLC) or set to Highlight Compensation (HLC) which masks overly bright light sources in the 
image, making certain features easier to make out.
