1. An image capture apparatus comprising: a face detection unit configured to detect a face that is included in an image; a subject detecting unit configured to track a subject by sequentially detecting an area similar to a template image of the subject in a sequence of images obtained by shooting; and a control unit configured to: determine, during tracking of the subject, reliability of the detection by the subject detecting unit, and if the face detected by the face detection unit has been set as the template image, not change the template image until it is determined a predetermined plurality of times in succession that the reliability of the detection by the subject detecting unit is low, and change the template image to another face that has been continuously detected for the predetermined plurality of times in succession if it has been continuously determined for the predetermined plurality of times in succession that the reliability of the detection by the subject detecting unit is low.
