Figure 6 IWI 5521 45mm Window
Both the 15mm and 45mm windows have an uncoated area on the inside. (Labeled side 2 in
Figure 5 and Figure 6). The other difference between the inside and the outside is that the
outside of the window is dark in appearance; whilst the inside shows rainbow hues when the light
strikes it at different angles.

6. Settings
Selecting the Basic tab gives the screen as shown in figure 7.
Figure 9 Basic Tab Screen shot.
6.1. Power
Allows the unit to be turned on and off.
6.2. Freeze image
Allows the image to be frozen.
6.3. Colour palette
Allows the selection of different colour palettes to suit the user.
6.4. Shutter
Allows the shutter to be operated automatically or turned off. In auto mode the shutter
operates more frequently when switched on until the electronics warm up and stabilise. It
will then shutter as required and at least once every 18 minutes.
6.5. Tracker
This displays a green box on the screen which tracks the hottest point in the scene.
6.6. Display mode
Relates to the gain and offset settings of the display. The IRI 5300 series cameras offer
both automatic adjustment and manual adjustment of the gain and offset to display the
scene. The gain is equivalent to altering the contrast of the image and the offset is
equivalent to brightness. Select between Manual mode and auto mode.
6.6.1. Automatic mode.
There are three types of automatic gain settings available. The Advanced settings section
provides more details of the extra settings available for the automatic modes. Example
images are shown in Figure 10 to Figure 16.

6.6.1.1. Linear(Mean)
In the Linear Mean mode the gain and offset are defined by the mean value of all the
temperatures in the selected region.(see section 7) Therefore when a hot or cold object
enters the scene there is little change in the brightness and contrast of the image.
(Figure 10 & 11)
6.6.1.2. Linear(Median)
In the Linear Median mode the maximum and minimum temperatures in the scene are
used to define the gain and offset of the displayed image. Therefore when a hot or cold
object enters the scene the brightness and contrast change rapidly to highlight the
object. (Figure 12 & 13) This setting can be altered further. – See section 7.
6.6.1.3. Histogram
In histogram mode the colours displayed are based on the temperature histogram of the
scene. As the display is dominated by the background, when a hot or cold object enters the
scene there is very little change in the brightness and contrast, making this mode more
suitable for video content analysis requiring a stable background scene. (Figure 14 & 15). For
more setting details see section 7.
