A user by halfway depressing (S 12 ) a shutter button acquires (S 13 , S 14 ) the output OR and the output OL of a sensor array. Subsequently, an operation judges whether or not the absolute value of the difference between the output OR and the output OL is greater than a threshold value (S 15 ). When judged greater than a threshold value, an operation initiates a warning notification to the user (S 17 , S 18 ) and AF processing by a contrast detection method is performed. Meanwhile, when judged less than a threshold value, the focus lens is moved so focus can be performed toward the distance to an object with a phase difference detection method (S 20 ). Then, the focus lens is moved from the existing focus lens position by a narrow range and the focus lens is moved to the lens position constituting the highest contrast value (S 21 ).
