A system controller of a digital camera has a function of detecting a face region from a captured image which is output from an imaging element, and sets a face region detected from a first captured image, as a reference image, searches for a similar region similar to a specific image which is a part of the reference image from a second captured image output after the first captured image, and detects a first region including the similar region in the second captured image and having the same size as the reference image, as the face region. The position of the specific image in the reference image and the position of the similar region in the first region coincide with each other.

A detection area is decided in a case where a target has gone out-of-frame. If a target is being imaged by a camera continuously, it is determined whether the target has gone out-of-frame. If the target has gone out-of-frame, then the magnitude and direction of motion of the camera are detected. If camera motion is large, it can be concluded that the camera user is imaging the target while tracking it. Accordingly, it can be concluded that the target will again be imaged at the center of the imaging zone. An area defined as a region in which the target will be detected is set at the center of the imaging zone. If camera motion is small in a case where the target goes out-of-frame, it can be concluded that the user is waiting for the target to re-enter the imaging zone and therefore the edge of the imaging zone is set as the detection area.

An image obtained by imaging a subject is displayed and a tracking frame is displayed at the central portion of a display screen. A target area is set surrounding the tracking frame and a high-frequency-component image is generated. A distance image indicating the distance to the subject image within an imaging zone is generated. An area, which represents a subject at a distance identical with that of the subject portion specified by the tracking frame displayed at the reference position, is decided upon as a search area. While a moving frame is moved within the search area of the high-frequency-component image, amounts of high-frequency component are calculated. The position of the moving frame at which the calculated amount of high-frequency component is maximized is adopted as the initial position of the tracking frame.
