Each frame of time-series pictures shot by a camera is converted to a spatial differential frame picture by the following equations: H(i, j) = UNION ¾ G(i+di, j+dj) - G(i, j) ¾ / (Gi, j, max / Gmax), I = Gmax / ä1 + exp(-0.02(H - 80))ü, where UNION denotes a sum over di = -1 to 1 and dj = -1 to 1, Gi,j,max denotes the maximum pixel value of 3x3 pixels having its center at the i-th row and j-th column, and Gmax denotes the assumable maximum value 255 of the pixel value G(i, j). Moving objects at a time t are discriminated based on a correlation between spatial differential frame pictures at times (t-1) and t and a discrimination result of moving objects included in the spatial differential frame picture at the time (t-1) .
