Abstract
Abstract An electronic view finder having an electronic display screen is provided with an electronic image source which produces an electronic image of a boundary frame and a neutral or black background with the electronic boundary frame being adjustable electronically in a predetermined manner when a binocular visioned viewer views the image of the electronic image with one eye and a scene with the other eye to produce an optically fused image of the scene and electronic image to the brain of the observer. When the electronic view finder is part of a video camera recording system which has a zoom lens, and a zoom lens control mechanism, the adjustment referred to electronically adjusts the boundary frame whereby the size of the bound frame is adjusted simultaneously or contemporaneously with the adjustment of the zoom lens. The image can be selectively presented either (1) the ordinary electronic video image of the scene being recorded or (2) the illuminated boundary frame.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
99 words
In an electronic view finder having an electronic display screen, means for producing an electronic image and means for causing said electronic image to cause a visual display on said display screen, the improvement wherein said electronic image is a boundary frame and a neutral background and means for electronically adjusting said boundary frame in a predetermined manner, whereby when a binocular visioned observer views the image of said electronic image with one eye and a scene with the other eye, an optically fused range of said scene and electronic image is presented to the brain of said observer.
Claim 2
Dependent Claim
99 words
In an electronic view finder having an electronic display screen, means for producing an electronic image and means for causing said electronic image to cause a visual display on said display screen, the improvement wherein said electronic image is a boundary frame and a neutral background and means for electronically adjusting said boundary frame in a predetermined manner, whereby when a binocular visioned observer views the image of said electronic image with one eye and a scene with the other eye, an optically fused range of said scene and electronic image is presented to the brain of said observer.
Claim 3
Dependent Claim
63 words
The electronic view finder defined in claim 1 wherein said electronic view finder is a part of a video camera recording system including a zoom lens and a zoom lens control means, and said means for electronically adjusting said boundary frame includes said zoom lens control means whereby the size of said boundary frame is adjusted contemporaneously with adjustments of said zoom lens.
Claim 4
Dependent Claim
43 words
The electronic view finder defined in claim 2 including image select switch means for selectively displaying on said electronic display screen (1) said electronic image of a boundary frame and a neutral background or (2) the scene being observed by said video camera.
Claim 5
Dependent Claim
39 words
The electronic view finder defined in claim 2 wherein said boundary frame is reduced in size as said zoom lens control means optically enlarges and said video camera records a portion of the scene viewed by said other eye.
Claim 6
Dependent Claim
88 words
In a method of presenting a framed image in the electronic image view finder of a video camera, the improvement wherein an electronic boundary frame light image is presented to one eye of a binocular visioned observer viewing said electronic image view finder and the other eye of said observer views the scene to be recorded by said camera, whereby an optically fused image of the respective scenes viewed through the two eyes of said binocular visioned observer is presented to the brain of said binocular visioned observer.
Claim 7
Dependent Claim
88 words
In a method of presenting a framed image in the electronic image view finder of a video camera, the improvement wherein an electronic boundary frame light image is presented to one eye of a binocular visioned observer viewing said electronic image view finder and the other eye of said observer views the scene to be recorded by said camera, whereby an optically fused image of the respective scenes viewed through the two eyes of said binocular visioned observer is presented to the brain of said binocular visioned observer.
Claim 8
Dependent Claim
44 words
The method defined in claim 5 wherein said camera has a zoom lens and a zoom lens control device and the area encompassed by said boundary frame light image is changed synchronously with changes in said zoom lens by said zoom lens control device.
Claim 9
Dependent Claim
46 words
A boundary setting device for a camera comprising: an electronic display screen means and means for causing a visual image of an adjustable boundary frame for defining the viewfield of a camera on an optically neutral background to be presented on said electronic display screen means.
Claim 10
Dependent Claim
46 words
A boundary setting device for a camera comprising: an electronic display screen means and means for causing a visual image of an adjustable boundary frame for defining the viewfield of a camera on an optically neutral background to be presented on said electronic display screen means.
Claim 11
Dependent Claim
42 words
The boundary setting device defined in claim 7 including a camera having a predetermined optical axis and means for mounting said boundary setting device on said camera so that said adjustable boundary frame surrounds a scene to be photographed by said camera.
Claim 12
Dependent Claim
44 words
The boundary setting device defined in claim 7 including a video camera, a zoom lens on said video camera, and means for causing contemporaneous operation of said means for causing a visual image of an adjustable boundary frame with operation of said zoom lens.
Claim 13
Dependent Claim
17 words
The invention defined in claim 7 wherein said optically neutral background is constituted by a black background.
Claim 14
Dependent Claim
19 words
The invention defined in claim 9 wherein said optically neutral background is an electronically formed on said electronic display.
Claim 15
Dependent Claim
41 words
The invention defined in claim 9 including selection switch means for selectively displaying on said electronic display (1) said visual image of an adjustable boundary frame on an optically neutral background or (2) the scene being observed by said video camera.
