Interpreting The Image – Relative Temperatures
The image displayed is simply a black and white picture of the infrared energy
entering the lens. The camera displays relative temperature differences between
individual objects and their surroundings irrespective of overall ambient
temperature.
The camera is set up to display objects at various shades between black for cooler
items and white for hotter bodies, e.g. in a room at 20
°
C a cold drink would appear
black whilst a hot radiator would appear white. However, in a room at 250
°
C, it is
possible that the same hot radiator may appear darker than, for example, burning
materials. Depending upon the application mode selected, the image may be
coloured according to actual temperature (Fire or Size Up mode) or relative
temperature (Overhaul, Inspection, WH, Missing Persons or BH mode).
