Apparatus and method

A method comprising:

• determining a first object through first determination;
• acquiring a first focus detection result by executing focus detection on the first object through first focus detection;
• controlling driving of a focus lens based on a focus detection result;
• determining a second object through second determination;
• acquiring a second focus detection result by executing focus detection on the second object through second focus detection;
• storing the second focus detection result;
• and
• judging whether the second object is an object to be tracked by the focus lens through judgment,
• wherein, in a case where the second object is judged as an object to be tracked by the focus lens, the first determination determines the second object as a new first object, and driving of the focus lens is controlled based on the second focus detection result.

An apparatus comprising:

• a first determination unit configured to determine a first object;
• a first focus detection unit configured to acquire a first focus detection result by executing focus detection on the first object;
• a first moving object detection unit configured to acquire a first moving object detection result by executing moving object detection on the first object;
• a control unit configured to control driving of a focus lens based on a focus detection result with respect to the first object;
• a second determination unit configured to determine a second object;
• a second focus detection unit configured to acquire a second focus detection result by executing focus detection on the second object;
• a second moving object detection unit configured to acquire a second moving object detection result by executing moving object detection on the second object;
• a storage unit configured to store the second focus detection result;
• and
• a judgment unit configured to judge whether the second object is an object to be tracked by the focus lens,
• wherein, in a case where the second object is judged as an object to be tracked by the focus lens based on the first moving object detection result and the second moving object detection result, the first determination unit determines the second object as a new first object, and the control unit controls driving of the focus lens based on the second focus detection result.

• acquiring a second focus detection result by executing focus detection on the second object through second focus detection;
• acquiring a second moving object detection result by executing moving object detection on the second object through second moving object detection;
• storing the second focus detection result;
• and
• judging whether the second object is an object to be tracked by the focus lens;
• wherein, in a case where the second object is judged as an object to be tracked by the focus lens based on the first moving object detection result and the second moving object detection result, the first determination determines the second object as a new first object, and driving of the focus lens is controlled based on the second focus detection result.

An apparatus comprising:

• a focus detection unit configured to execute focus detection based on a signal output from an image sensor;
• a control unit configured to control driving of a focus lens;
• a first determination unit configured to determine a main object to be tracked by the focus lens after the control unit controls driving of the focus lens to adjust a focus on an object detected based on a result of the focus detection,
• wherein the first determination unit determines a first object based on object conspicuousness having a difference between a focus detection result and a position corresponding to the object which is less than a threshold value.
