In a method and device for determining the stationary position of the line of sight of a video filming device subject to periodic vibrations, the video signal produced by the device is sampled by means of sampling signals coming from a vibration detector detecting the vibrations. The image observed by the filming device is reconstituted using the sampled video signals, and the position of the stationary reconstituted image corresponding to the stationary line of sight is determined from the reconstituted image.

This invention relates to a system for adjusting the relative angular positions of two video cameras directed towards the same object, characterized in that it comprises:--structure for synchronizing the actions of said cameras;--structure for displaying the video signals issuing from said cameras, these display structures being common to said cameras;--and a device for addressing to said display structure a succession of images which come, alternately, from one and the other of said cameras. The system of the invention is more particularly applicable to the adjustment of the axes of two apparatus, for example the firing axis of a weapon and the axis of sight of a viewfinder.
