Abstract
An image-pickup apparatus is disclosed which can prevent focus control from being performed on the basis of incorrect information on an object distance externally measured. The image-pickup apparatus includes a first detector which produces first information corresponding to a contrast state of a picked-up image, a second detector which receives light from an object to detect second information corresponding to a distance to the object, and a controller which performs focus control by using the first information and the second information. The controller performs the focus control by using the first information without using the second information when a light-receiving luminance level in the second detector is lower than a first value.
