A method for displaying a thermal image is provided, in which one color of a color palette is assigned in each case to one temperature range of the thermal image. The colors are assigned to the temperature ranges depending on whether certain criteria of the temperature distribution occur in a geometric region of the thermal image.

The embodiment of the present disclosure relates an image processing method, an electronic device and a computer-readable storage medium, the image processing method, includes: acquiring a first image; detecting a feature region in the first image to obtain a detection result of the feature region; in which the feature region is a region with a specified feature; determining a first transmissivity corresponding to the first image based on the detection result of the feature region; and determining an image de-graying intensity based on the first transmissivity, and performing de-graying processing on the first image according to the image de-graying intensity so as to obtain a second image.
