Claim One:
1. An image fusing method for fusing a thermal image and a visible image of a subject, the image fusing method comprising: detecting an important pixel of the thermal image based on a luminance value of each pixel of the thermal image; detecting a first important pixel and a second important pixel of the visible image based on a luminance value of each pixel of the visible image; setting a pixel coefficient for each pixel of the thermal image according to whether each pixel of the thermal image is the important pixel and whether each pixel of the visible image is at least one of the first important pixel and the second important pixel; generating another thermal image by applying the pixel coefficient to the luminance value of each pixel of the thermal image; and fusing the other thermal image and the visible image to generate a fused image, at an image fusing controller, wherein the detecting the important pixel comprises: determining the important pixel of the thermal image of which a luminance value is equal to or greater than a first reference value calculated based on a mean of luminance values of the thermal image; determining the first important pixel of the visible image of which a luminance value is equal to or greater than a second reference value calculated based on a mean of luminance values of the visible image; and determining the second important pixel of the visible image of which a luminance value is equal to or greater than a third reference value calculated based on a mean of luminance values of the visible image.
