A method for enhancing wide dynamic range in images is disclosed. The method comprises acquiring at least two images of a scene to be imaged, the images acquired using different exposure times. For a first image an illumination mask is constructed corresponding to the illumination in the scene, comprising a set of continuous weight values distinctively identifying respective areas of pixels of high or low illumination, over-exposed or underexposed with respect to a predetermined threshold illumination value, assigning one of the weight values to each pixels, whereas other weight value is assigned to other pixels of the other images. A spatial low-pass filter is used to smooth border zones on the illumination mask, thus assigning pixels in the border zones new continuous weight values in a range between the weight values. A combined image is constructed using combined weight values with image data of pixels assigned with one weight value of the first image and image data of pixels assigned with other weight value of the other images and in pixels corresponding to the border zones using image data from the images proportional to the new weight values.
