stable
Compare with room
temperature, the quality of
image in low temperature is
quite poor.
When temperature is above 0 Celsius, the object and background have
different thermal conductivity which lead to large temperature difference.
Image quality is higher in this case. In low temperature, object and
background have similar temperature, that lead to small temperature
difference, then poor image quality. This is a feature of thermal imaging
device.
