Abstract: Disclosed herein is a method and apparatus for processing a thermal image. The method includes: performing histogram stretching on thermal image data of the thermal image; and adjusting a histogram stretching scale for thermal image data of a next frame using histogram data of the thermal image data on which the histogram stretching is performed. As a result, it is possible to mitigate that an image becomes less recognizable as thermal image data is deteriorated or saturated.
