1. An apparatus comprising:
an acquisition unit configured to acquire a captured image from a camera that is capable of controlling an orientation;
a display control unit configured to display the captured image onto a display screen;
a detection unit configured to detect, within the display screen, a subject at which a user is looking continuously for at least a first reference duration; and
an orientation changing unit configured to calculate, from a transition of a displayed image displayed on the display control unit, a moving speed of the subject within the displayed image, and to change an orientation of the camera, in response to a judgement that the subject falls out of the displayed image after a second reference duration has elapsed, in such a way that the subject does not fall out of the displayed image.
