Black/White Hot, Color and Edge Detect modes
Pressing and releasing Switch (4) (marked
MENU
and corresponding icon) cycles through Black
Hot,
White
Hot,
Color
and
Edge
Detect
modes
(in
sequence).
Black Hot mode displays the heat sources as black. The cooler objects are displayed as
increasingly lighter shades of gray while the coldest objects are displayed as white.
White Hot mode displays the heat sources as white. The cooler objects are displayed as darker
shades
of
gray
while
the
coldest
objects
are
displayed
as
black.
NOTE:
If preferred, Color mode and Edge Detect modes can be turned on and off under Video
Settings Menu in Menu Mode.
Color mode assigns different colors to different temperatures and displays areas with different
colors depending on their temperatures.
Edge Detect mode darkens areas of the image that are algorithmically not important and outlines
objects that produce distinctive heat signature. This helps users stay focused for longer periods
of time and quickly identify object of interest when it becomes visible.
Contrast Enhancement (CE) Adjustment
CE adjustment allows the user to increase or decrease algorithmic contrast adjustment of the
image. CE adjustment changes parameters in a complicated gain and contrast adjustment logic
that are tailored to make object(s) of interest appear as clear as possible.
NOTE 1
: Different CE Adjustment settings maybe required for different observation conditions.
NOTE 2:
CE Adjustment can be required when switching between radically different scenes,
switching polarity of the image, etc.
Menu Mode Description
Refer to Figure 8.
Menu Mode allows user to conduct system configuration (choose brightness, contrast, enabled
functionality, etc.) and review some of the sy
stem’s parameters (part number and software
revision). To enter the Menu Mode press and hold Switch (4) (
MENU
) for approximately three
seconds.
