Claim One:
1. A following device with a pan head on which a camera is mounted moving to move shooting directions of said camera while taking in images shot by said camera one after another so as to extract images of a moving object by comparing taken-in images and to control moving velocity of said pan head based on positions on a screen of images of said moving objects so as not to dispose said moving object outside a shooting range of said camera, comprising: a moving object image extraction device to extract image of said moving object based on images taken in from said camera; a moving velocity detection device to detect moving velocity of said moving object from positional changes on the screen of images of said moving object extracted by said moving object image extraction device; and a control device to control moving velocity of said pan head based on the moving velocity of said moving object obtained by said moving velocity detection device so that said moving object does not get out of the shooting range.
