Abstract:
1. A control system for a camera, comprising: a memory configured to store coordinate data of a predetermined pseudo subject-plane representing a plane virtually covering people in a room to be shot with the camera, wherein the predetermined pseudo subject-plane is defined by three-dimensional coordinates in the room, and wherein the camera is provided at a predetermined position in the room, the position of the camera being identified by the three-dimensional coordinates in the room; a display unit provided at a place remote from the room and configured to instruct a direction of the camera based on an input by a user viewing an image displayed on the display unit, whereby an image of one or more persons in the room the user is interested in is captured by the camera; a determining unit configured to determine coordinates of an intersection point of a straight line from the camera extending in the direction instructed by the directing device with the pseudo subject-plane read from the memory; a distance calculating unit configured to calculate the distance from the camera to the intersection point based on the coordinates of the camera and the intersection point; and a zoom calculating unit configured to calculate a zoom amount of the camera needed to produce a predetermined shooting range based on the distance calculated by the distance calculating unit.
