Once an imaging mode is set, an imaging apparatus displays a through image with a tracking frame on the predetermined position. If a shutter button is pressed halfway, an object that is overlapped by the tracking frame is recognized as a main subject that a user wants to capture. Until the shutter button is fully pressed or until the halfway-press is released, it is detected where the recognized subject is in frame image data that is captured in sequence, and the tracking frame is displayed based on the detected position. If the halfway press of the shutter button is released before the shutter button is fully pressed, the tracking frame is displayed on the predetermined position. Then if the shutter button is pressed halfway once again, the process is repeated.
