the dynamic processing device includes a pixel value analyzing unit, which is respectively connected to the template customizing unit and the target judging unit, and configured to determine, for each contour pixel constituting the target contour, different filtering strategies according to a pixel distribution within a median filtering window centered thereon based on the median filtering template, where determining different filtering strategies according to a pixel distribution within a median filtering window centered thereon based on the median filtering template includes: when the number of target pixels in the median filtering window is larger than or equal to the number of non-target pixels in the median filtering window, taking the average value of the pixel values of all the target pixels as the pixel value of the contour pixel, and when the number of the target pixels in the median filtering window is smaller than the number of the non-target pixels in the median filtering window, taking the average value of the pixel values of all the non-target pixels as the pixel value of the contour pixel;
the pixel value analysis unit is further used for taking the mean value of the pixel values of all pixels in a median filtering window which takes the median filtering template as the center as the pixel value of each non-contour pixel which does not belong to the target contour in the refrigerator interior image based on the median filtering template; the pixel value analysis unit outputs a dynamic processing image.
