Abstract

Abstract 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.

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 117 words
A system for adjusting the relative angular positions of two video cameras directed towards the same object, comprising: means for synchronizing the actions of said cameras; means for displaying the video signals issuing from said cameras, these display means being common to said cameras; and means for addressing to said display means a succession of images which come, alternately, from one and the other of said cameras, the image from one of said cameras being an even-row image, and the image from the other of said cameras being an odd-row image, said images being interlaced in said display means and forming a single view of said object when both of said cameras are directed towards the object.
Claim 2
Independent Claim 117 words
A system for adjusting the relative angular positions of two video cameras directed towards the same object, comprising: means for synchronizing the actions of said cameras; means for displaying the video signals issuing from said cameras, these display means being common to said cameras; and means for addressing to said display means a succession of images which come, alternately, from one and the other of said cameras, the image from one of said cameras being an even-row image, and the image from the other of said cameras being an odd-row image, said images being interlaced in said display means and forming a single view of said object when both of said cameras are directed towards the object.
Claim 3
Dependent Claim 14 words
The system of claim 1, wherein at least one of said cameras is orientable.
Claim 4
Dependent Claim 17 words
The system of claim 2, wherein one of the cameras is fixed, whilst the other is orientable.
Claim 5
Dependent Claim 96 words
The system of claim 1, wherein said means addressing to the display means the images of the two cameras comprise an image commutation device provided with two inputs respectively receiving the video signals of said cameras and with a single output connected to said display means, said image commutation device being adapted to take one or the other of two alternate positions of which one connects one of said inputs with said output and the other connects the other of said inputs with this output, at the rhythm of the synchronization pulses of said video images.
Claim 6
Dependent Claim 52 words
The system of claim 4, wherein said image commutation device is controlled by a monostable multivibrator, of which the input receives the succession of the synchronization pulses of the video images and of which the output controls the alternate tipping of said commutation device from one of its positions to the other.
Claim 7
Independent Claim 171 words
A system for adjusting the relative angular positions of two apparatus towards the same object, comprising: a first video camera rigidly connected to the first of said apparatus so that its shot-taking axis is at least substantially merged with the axis of said first apparatus; a second video camera rigidly connected to the second of said apparatus so that its shot taking axis is at least substantially merged with the axis of said second apparatus; means for synchronizing the actions of said cameras; means for displaying the video signals issuing from said cameras, these display means being common to said cameras; and means for addressing to said display means a succession of images from one and the other of said cameras, the image from one of said cameras being as even-row image, and the image from the other of said cameras being an odd-row image, said image being interlaced in said display means and forming a single view of said object when both of said cameras are directed towards the object.
Claim 8
Independent Claim 171 words
A system for adjusting the relative angular positions of two apparatus towards the same object, comprising: a first video camera rigidly connected to the first of said apparatus so that its shot-taking axis is at least substantially merged with the axis of said first apparatus; a second video camera rigidly connected to the second of said apparatus so that its shot taking axis is at least substantially merged with the axis of said second apparatus; means for synchronizing the actions of said cameras; means for displaying the video signals issuing from said cameras, these display means being common to said cameras; and means for addressing to said display means a succession of images from one and the other of said cameras, the image from one of said cameras being as even-row image, and the image from the other of said cameras being an odd-row image, said image being interlaced in said display means and forming a single view of said object when both of said cameras are directed towards the object.
Claim 9
Dependent Claim 15 words
The system of claim 6, wherein at least one of the apparatus-camera assemblies is orientable.
Claim 10
Dependent Claim 20 words
The system of claim 7, wherein one of the apparatus-camera assemblies is fixed, whilst the other apparatus-camera assembly is orientable.
Claim 11
Dependent Claim 96 words
The system of claim 6, wherein said means addressing to the display means the images of the two cameras comprise an image commutation device provided with two inputs respectively receiving the video signals from said cameras and with a single output connected to said display means, said image commutation device being adapted to take one or the other of two alternate positions of which one connects one of said inputs with said output and the other connects the other of said inputs with this output, at the rhythm of the synchronization pulses of said video images.
Claim 12
Dependent Claim 52 words
The system of claim 9, wherein said image commutation device is controlled by a monostable multivibrator of which the input receives the succession of the synchronization pulses of the video images and of which the output controls the alternate tipping of said commutation device from one of its positions to the other.
