PURPOSE: An auto focusing method is provided to detect an optimized point, thereby increasing scan speed while keeping detection accuracy. CONSTITUTION: A focus value of each site is detected after moving from an initial start point as many as 3 or 7 steps. Patterns of detected focus values are compared/analyzed to determine the first scan direction(S16). The first scan is performed in the determined first scan direction(S20). The second scan is performed in an optimized section during the first scan(S30,S40).
