PROBLEM TO BE SOLVED: To avoid responsiveness up to focusing from remarkably getting worse, without decreasing accuracy of focus detection.SOLUTION: A focus detector including a first mode in which auxiliary light is projected to an object when detecting a focus and a second mode in which the auxiliary light is not projected to the object when detecting the focus includes control means allowing focus detection processing in the first mode (S401) and then, allowing focus detection processing in the second mode when the detection result in the first mode is reliable (S404), but not allowing focus detection processing in the second mode when the detection result in the first mode is not reliable (NO in S403). |
