Summary:To enable focus control capable of reducing cost and power consumption and downsizing.Machine learning is performed to generate a depth map. A control unit 134b performs focus control by using a depth map generated by a depth calculation unit 134, and switches to different control between a tracking mode for tracking a predetermined subject a non-tracking mode for not tracking the predetermined subject. For example, in a case of the tracking mode, focus control to focus on the predetermined subject searched for on the basis of subject distance information generated by using the depth map is performed. In a case of the non-tracking mode, focus control to focus on the subject at the nearest position indicated by the subject distance information generated by using the depth map is performed. Even if a ranging sensor is not provided, the focus control according to the tracking mode or the non-tracking mode can be performed by using the depth map generated on the basis of the captured image.
