Composition control device, imaging system, composition control method, and program

摘要

A composition control device includes: a composition determination unit which determines a target composition, the composition determination unit determining zoom magnification and a target position of the subject in an image region; a preliminary position obtaining unit which obtains, as a preliminary position, a position of the subject, before a field angle is changed according to the zoom magnification, in a case where the target position is obtained; a movable mechanism section control unit which performs a control for a movable mechanism section which changes an imaging view range of the imaging section so that the position of the subject corresponds to the obtained preliminary position; and a zoom control unit which performs a driving control for a zoom lens of the imaging section so that the field angle is obtained according to the zoom magnification after the image region of the subject is disposed in the preliminary position.
