13. MAIN MENU (SETTINGS)
Note:
The Lens option only appears in the menu in case the GIS 320 camera has been calibrated for use
with multiple exchangeable thermal lenses.
13.7.2 Visible Camera
Visible Camera submenu allows user to set the parameters common to many regular digital video cameras. It
also allows these parameters to be reset to their default values.
Figure 13.10: Visible Camera submenu.
VISIBLE CAMERA submenu consists of the following items:
GAMMA ‐ cycles between STANDARD, STRAIGHT, NARROW and WIDE. This changes the gamma curve used
for mapping and compression of the values observed by the camera.
WHITE BALANCE ‐ cycles between WIDE, NARROW, INDOOR, OUTDOOR. WIDE and NARROW are automatic
modes which cover color temperature range from about 10000K to 2200K and about 7000K to 2500K
respectively. INDOOR and OUTDOOR are fixed color temperature balance modes for about 3200K and
5800K respectively.
VIBRATION COMPENSATION ‐ toggles ON and OFF. Optical vibration compensation is implemented mechanically
and attempts to decrease blurring and shaking effects. It’s mostly effective against vibrations within the
frequency range of 2‐17Hz.
BACKLIGHT COMPENSATION ‐ toggles ON and OFF. Backlight compensation attempts to ignore small, very
bright areas of the scene when determining the correct exposure settings which may allow intensely backlit
objects still remain well visible in the resulting image. This is at the cost of potentially losing detail in very
bright areas of the image.
WIDE DYNAMIC RANGE MODE ‐ toggles ON and OFF. Wide dynamic range cleverly maps the observed
brightness levels through the image to bring more contrast out of areas that’re in shadow or uneven light,
