COMPOSITION CONTROL DEVICE, IMAGING SYSTEM, COMPOSITION CONTROL METHOD, AND PROGRAM
First Claim
1. A composition control device comprising:
- composition determination means which is configured to determine a target composition on the basis of information about a subject detected from an image captured and obtained by an imaging section, the composition determination means determining zoom magnification for obtaining the target composition and a target position of the subject in an image region for obtaining the target composition;
preliminary position obtaining means which is configured to obtain, as a preliminary position, a position of the subject obtained in the image, before a field angle is changed according to the zoom magnification, in a case where the target position determined by the composition determination means is obtained; and
zoom control means which is configured to perform a driving control for a zoom lens of the imaging section so that the field angle is obtained according to the zoom magnification determined by the composition determination means after the image region of the subject is disposed in the preliminary position by means of a movable mechanism section control which is configured to perform a control for a movable mechanism section which is configured to change an imaging view range of the imaging section so that the position of the subject in the image region corresponds to the obtained preliminary position.
