<p><P>PROBLEM TO BE SOLVED: To determine a direction of movement of an AF lens when focusing. <P>SOLUTION: A controller 104 detects the edge of each color component and calculates a differential value of the edge strength of each color component. The controller 104 determines, on the basis of the calculated differential value of the edge strength of each color component, the direction of movement (driving direction) of the AF lens. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
