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.
