Slow Speed Shutter 
The Slow shutter can be turned “ON” if the sensitivity is still not so 
good under “High” gain condition at dark. The optimum image level can 
be maintained by appropriate gain and shutter combination which are 
determined automatically inside camera system.  
As slow shutter activates, the exposure time becomes longer and 
frame rate becomes smaller. Blurred images sometimes are prominent 
with moving objects. 
Back Light Compensation 
Set an area for backlight compensation. If backlight compensation is 
activated, the camera performs the exposure control only within the 
specified area. 
Backlight compensation is a function that achieves the brightness of a 
selected area to an optimum image level. This function is necessary 
when an auto iris lens tends to close due to an intense light coming 
from the back of the object in the area to be viewed so that areas 
become dark and visibility deteriorates. In this case, set the area so 
that the portion to be viewed is within the selected area. The area size 
is roughly as shown in Fig. 2 below. 
Sharpness 
Set a sharpness effect. 
“Sharp”:  sharpness is strong. 
“Soft”:      sharpness is weak. 
Gamma 
“1”:  May be selected for some specific area, such as FA application for 
obtaining true video data. 
“0.45”:  This is default, suitable for CCTV application 
White Balance 
Set the white balance values to meet the environment condition for 
best colour rendition. 
z
 
“AWB”: the colour of camera is automatically adjusted according to 
external lighting condition. 
z
 
“Manual”: Adjustable by user manually, this is useful for some 
specific condition which AWB may be unaffordable to perform 
correctly. 
z
 
“Indoor”: Default for 3200K condition 
z
 
“Outdoor” Default for 5100K condition 
Iris Adjustment 
19 steps of offset level from -9 to +9 are available to adjust the image 
level for an DC auto iris lens. Images become brighter as higher the 
level is and becomes darker as lower the level is.
