Colour palette

The "Colour Palette" menu allows you to change the fake colour of the infrared
image displayed or captured on the screen. A range of colour palettes is available
for use. Some colour palettes are more applicable to the special areas, so they
are set as required options. The grayscale colour palette offers balanced linear

applies to the warm-cold contrast situation. It is used to enhance the colour
contrast of high-temperature and low-temperature images. Iron red and rainbow
