Apparatus and method for determination of a focus detection target

An apparatus comprising:

• at least one processor;
• and
• a memory coupled to the at least one processor, the memory having instructions that, when executed by the processor, performs operations as:
• 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 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 a first object detected based on a result of the focus detection,
• wherein the determination unit determines a second object as the main object based on conspicuousness in a case where a focus detection result corresponding to the second object is smaller than a first threshold value, and determines the main object regardless of the conspicuousness in a case where the difference between the focus detection result and the position corresponding to the second object is greater than or equal to the first threshold value.
