Abstract
Systems and methods for allocating display colors to thermal image intensity data acquired by thermal band photodetectors. Intensity data from the photodetectors corresponding to scene temperature is converted to a digital value within an analog to digital conversion (ADC) range. The full ADC range may be divided into two or more sub-ranges. In one sub-range, intensity values within that sub-range are assigned display colors from a first color table utilizing one or more Histogram Equalization (HE) techniques. In another sub-range, specific display values from a color table different from the first may be are assigned to specific intensity values. Lower temperatures may be assigned colors using HE and higher temperatures are assigned specific colors corresponding to specific temperatures. Such an arrangement is particularly applicable to thermal imaging use by firefighters because the arrangement allows them to determine temperature directly from displayed color for potentially dangerous temperatures.
