An image processing method using a first image sensor covering the visible range and a second sensor covering the infra-red range. The method includes a) acquiring a first image Iof said given zone of space by means of the first image sensor, b) acquiring a second image Iof said given zone of space by means of the second image sensor, c) performing a decomposition of the first image Iso as to obtain at least one luminance image I, d) obtaining an image Iresulting from digital fusion of the luminance image Iand of the second image I, e) adding colour information to the fusion image Ior during the fusion stage d).

Method for processing images

An remote optical gas detection device comprising a detection housing () connected to an electronic power supply unit and to a human-machine interface, this detection housing containing an infrared lens () for forming an image on an uncooled microbolometer matrix detector (), a CCD or CMOS-type camera () for observing the observed region under visible light, an assembly of electronic means () for controlling the detector and for acquiring and digitizing the infrared signals, as well as a processor () for processing these signals in order to detect a gas in the observed region and to determine the concentration thereof.
