  • Patent number: 12276899
    Abstract: The present invention provides an image pickup device that recognizes the object that the user is attempting to capture as the subject, tracks the movement of that subject, and can continue tracking the movement of the subject even when the subject leaves the capturing area so that the subject can always be reliably brought into focus. The image pickup device includes a main camera that captures the subject; an EVF that displays the captured image captured by the main camera, a sub-camera that captures the subject using a wider capturing region than the main camera, and a processing unit that extracts the subject from the captured images captured by the main camera and the sub-camera, tracks the extracted subject, and brings the subject into focus when an image of the subject is actually captured. When the subject moves outside of a capturing region of the main camera, the processing unit tracks the subject extracted from the captured image captured by the sub-camera.
