Abstract
A focus control device that has an image sensor that receives light flux that has passed through a photographing lens and is capable of generating a phase difference detection signal, and that executes focus adjustment based on the phase difference detection signal, the focus control device comprising a focus detection circuit that detects ranging data representing defocus amount based on phase difference detection signals of a plurality of focus detection regions that have been set in a region of the image sensor where the light flux is received, and a processor that, with ranging data corresponding to a plurality of focus detection regions being arranged in order of short distance, performs focus adjustment based on ranging data remaining after excluding ranging data in a specified range from ranging data representing a closest range.
