[Problem] To realize focus control that can be reduced in size and cost and power consumption. Machine learning is performed to generate a depth map. The control unit 134b performs focus control by using the depth map generated by the depth calculation unit 134, and switches to different control between a tracking mode for tracking a predetermined subject and a non-tracking mode in which the predetermined subject is not tracked. For example, in the case of a tracking mode, focus control is performed that focuses on a predetermined subject searched based on subject distance information generated by using a depth map. In a non-tracking mode, focus control is performed that is focused on a subject at a nearest position indicated by subject distance information generated by using a depth map. Even if a distance measuring sensor is not provided, focus control according to a tracking mode or a non-tracking mode can be performed by using a depth map generated based on a captured image. 为了实现能够降低成本和功耗并且小型化的聚焦控制。执行机器学习
