1. An image capture apparatus comprising:
an irradiation unit configured to apply illumination toward a subject;
a first image capture unit;
one or more processors; and
a memory storing a program which, when executed by the one or more processors, causes the image capture apparatus to function as:
a first image acquiring unit configured to acquire a first image by capturing an image of the subject in a first exposure condition with the first image capture unit in a state where the illumination is not applied toward the subject;
a first determining unit configured to determine a first irradiation amount used by the irradiation unit, and a second exposure condition in accordance with the first image;
a second image acquiring unit configured to acquire a second image by capturing an image of the subject in the second exposure condition with the first image capture unit in a state where the illumination is applied toward the subject with the first irradiation amount;
a third image acquiring unit configured to acquire a third image by capturing an image of the subject in the second exposure condition with the first image capture unit in a state where the illumination is not applied toward the subject;
a shake detection unit configured to detect a movement of at least one of the image capture apparatus and the subject; and
a status detection unit configured to detect a status of the subject by using a difference image between the second image and the third imagery,
wherein, when the shake detection unit has not detected the movement, the status detection unit is configured to detect a status of the subject by using the difference image.
