Then, a display line flag value of each display line is obtained according to horizontal block flag values of all of the horizontal blocks of the display line. Next, M vertical block flag values are obtained according to the display line flag values of all of the display lines in each vertical block. Then, it is determined whether or not the display mode has to be switched according to the M vertical block flag values.
