Claim 18:
19. A method comprising:
receiving a first captured image frame comprising a plurality of pixels having a first range of associated pixel values;
receiving a selection of a subset of the pixels, wherein the subset comprises a scene feature;
determining a span associated with the pixels of the subset having a second range of associated pixel values smaller than the first range;
wherein the span comprises a first limit associated with the scene feature and a second limit associated with an expected gas feature;
receiving a second captured image frame comprising the scene feature and the gas feature; and
scaling the second captured image frame to provide an adjusted image frame limited to the second range of pixel values associated with the span to increase contrast between the gas feature and the scene feature.
