Claims (6)

Acquisition means for acquiring images continuously captured using an image sensor;
With respect to the image, by image recognition, and the first object detecting means for continuously detecting a predetermined subject,
Of the image, with respect to the first object detecting means a plurality of images picked up continuously during the image to be detected of the predetermined object, detected by the first object detecting means and the Second object detection means for detecting the object by sequentially detecting movement of the area of the object;
A discriminating means for discriminating whether or not a predetermined condition is satisfied for at least one of a gain adjustment amount applied to the image or an exposure time of an image sensor when capturing the image;
Determining means for determining an area of the predetermined subject in the image acquired by the acquiring means;
The determining means is
When the determination means determines that the predetermined condition is satisfied, the predetermined subject area is determined based only on the subject detection result by the first subject detection means;
If the determination means does not determine that the predetermined condition is satisfied, the predetermined subject area is determined based on the subject detection results by the first subject detection means and the second subject detection means. Decide
2. The imaging apparatus according to claim 1, wherein the predetermined condition is that the gain adjustment amount exceeds a predetermined threshold value or the exposure time is longer than a predetermined threshold value. Sensitivity The gain adjustment amount, the image is larger value the higher the setting of the imaging sensitivity when imaged, said determining means, for setting the imaging sensitivity when the image is captured it is predetermined The imaging apparatus according to claim 1, wherein it is determined whether or not the gain adjustment amount satisfies the predetermined condition by determining whether or not the threshold value exceeds a predetermined threshold value.   3. The apparatus according to claim 1, further comprising a stopping unit that stops the operation of the second subject detecting unit when the determining unit determines that the predetermined condition is satisfied. The imaging device described.   The imaging apparatus according to claim 1, wherein the first subject detection unit detects a human face as the predetermined subject. An acquisition step in which an acquisition unit acquires images continuously captured using an image sensor;
A first subject detecting means, wherein the image, by image recognition, the first subject detecting process of continuously detecting a predetermined subject,
The second subject detection means applies the first subject to a plurality of images captured continuously between images in which the predetermined subject detection is performed in the first subject detection step. A second subject detection step for detecting the subject by sequentially detecting the movement of the region of the subject detected in the subject detection step;
Determining means, for at least one of exposure time of the imaging device when imaging the gain adjustment amount or the image is applied to the image, a determination step of determining whether a predetermined condition is satisfied,
Determining means, and a determination step of determining the area of the object in the image acquired by said acquisition step,
In the determining step , the determining means includes :
If it is determined by the determination step that the predetermined condition is satisfied, the region of the subject is determined based only on the subject detection result by the first subject detection step;
If it is not determined by the determination step that the predetermined condition is satisfied, the region of the subject is determined based on a subject detection result obtained by the first subject detection step and the second subject detection step;
The control method for an imaging apparatus, wherein the predetermined condition is that the gain adjustment amount exceeds a predetermined threshold value or the exposure time is longer than a predetermined threshold value.   A program for causing a computer included in an imaging apparatus to execute each step of the control method for the imaging apparatus according to claim 5.
