Document Type and Number:
WIPO Patent Application WO/2023/286301
Kind Code:
A1
Abstract:
According to the present invention, reduction of cost and power consumption and miniaturization can be achieved, and focus control can be carried out. In the present invention, machine learning is executed, and a depth map is generated. A control unit 134b carries out focus control by using the depth map generated by a depth calculation unit 134, and switches control so as to be different between a tracking mode for tracking a prescribed object and an untracking mode for not tracking the object. For example, in the tracking mode, the focus control focusing on the prescribed object searched for on the basis of distance information of the object generated by using the depth map is carried out. In the untracking mode, the focus control focusing on an object at a nearest position indicated by the distance information of the object generated by using the depth map is carried out. Even without providing a ranging sensor, the focus control can be carried out in accordance with the tracking mode or the untracking mode by using the depth map generated on the basis of a captured image.
