1. A full-automatic detection method for static characteristic information in a dynamic image, wherein the full-automatic detection method for static characteristic information in a dynamic image at least comprises:

  • (1) judging whether a pixel is a static information pixel or not by comparing an inter-frame difference with a predetermined threshold in a predetermined first region and second region;

    the judging process is stopped when the pixels in the non overlap region of the first and second region are judged as non-static information points; and

    (2) determining static characteristic information in the dynamic image based on the static information points in the first region;

    wherein when the static information points in the first region are determined as belonging to the static characteristic information in the dynamic image, the steps (1) and (2) are repeated based on an adjusted predetermined threshold.
