Abstract

Abstract A camera includes means for separating an image to be photographed into in plurality of picture elements. These picture elements are transmitted by means of fiber optics or by means of opto-electrical converters to a view finder which displays the image to be photographed as a raster image. Said means for separating the image to be photographed is arranged close to the plane of a film or in a plane conjugate to the plane of a film.

Claims Analysis

Total Claims: 15
Claim 1
Independent Claim 109 words
A camera comprising: a picture-taking objective capable of reproducing objects to be photographed; a screen comprising a plurality of elements for receiving and separating an image from said objective into a plurality of image elements; a focal-plane shutter having a curtain connected with said screen; transmitting means for transmitting information from said screen to at least one viewfinder so as to display therein the picture seen by said objective; and at least one roll for winding said curtain of said focal-plane shutter, said roll comprising at least one slot for receiving said curtain and said screen, said transmitting means emerging from said roll and being connected to said viewfinder.
Claim 2
Dependent Claim 109 words
A camera comprising: a picture-taking objective capable of reproducing objects to be photographed; a screen comprising a plurality of elements for receiving and separating an image from said objective into a plurality of image elements; a focal-plane shutter having a curtain connected with said screen; transmitting means for transmitting information from said screen to at least one viewfinder so as to display therein the picture seen by said objective; and at least one roll for winding said curtain of said focal-plane shutter, said roll comprising at least one slot for receiving said curtain and said screen, said transmitting means emerging from said roll and being connected to said viewfinder.
Claim 3
Dependent Claim 40 words
A camera as defined in claim 1 wherein said viewfinder includes a device for displaying the picture seen by the objective and an ocular in position opposite to said device, the distance between said ocular and said device being variable.
Claim 4
Dependent Claim 52 words
A camera, as defined in claim 2, wherein an adjusting wheel for moving the ocular relative to said device is provided, said adjusting wheel comprising markings the relative positions of which are indicative for a defined position, said defined position indicating the focus of the objective for which said ocular is adjusted.
Claim 5
Dependent Claim 114 words
A camera comprising: a camera housing; a picture-taking objective capable of reproducing objects to be photographed on a plane of a film; at least one viewfinder for viewing the objects to be photographed; at least one screen comprising a plurality of elements for separating an image into a plurality of image elements, said screen being at least temporarily located in a plane intermediate said objective and said film plane and in the axis of the light beam of the objective so as to receive information transmitted from said objective towards said film plane; and means for transmitting the information from said screen to said viewfinder to transmit thereto the picture seen by the objective.
Claim 6
Dependent Claim 114 words
A camera comprising: a camera housing; a picture-taking objective capable of reproducing objects to be photographed on a plane of a film; at least one viewfinder for viewing the objects to be photographed; at least one screen comprising a plurality of elements for separating an image into a plurality of image elements, said screen being at least temporarily located in a plane intermediate said objective and said film plane and in the axis of the light beam of the objective so as to receive information transmitted from said objective towards said film plane; and means for transmitting the information from said screen to said viewfinder to transmit thereto the picture seen by the objective.
Claim 7
Dependent Claim 26 words
A camera as defined in claim 4 wherein said image elements comprise a plurality of light-conducting fibers arranged so as to form a fiber optic sheet.
Claim 8
Dependent Claim 23 words
A camera, as defined in claim 4, wherein said screen is an integral part of at least one curtain of a focal-plane shutter.
Claim 9
Dependent Claim 42 words
A camera according to claim 4 said plurality of elements of said screen comprising first ends of light-conducting fibers, said viewfinder comprising an imaging screen having a plurality of light-emitting elements, said light-emitting elements being the second ends of said light-conducting fibers.
Claim 10
Dependent Claim 57 words
A camera according to claim 4 said plurality of elements of said screen comprising opto-electrical converters, said viewfinder comprising an imaging screen having a plurality of light-emitting elements, said light-emitting elements comprising electro-optical converters; and electrical conductors for connecting said opto-electrical converters to said electro-optical converters so that the viewfinder shows the picture seen by said objective.
Claim 11
Dependent Claim 43 words
A camera as defined in claim 4, said camera further comprising: a translucent casing arranged in said housing; a reflector turnably mounted in said translucent casing; a flash lamp arranged in said reflector; and means for turning said reflector in said transparent casing.
Claim 12
Dependent Claim 75 words
A camera comprising: a picture-taking objective capable of reproducing a plurality of elements to be photographed; at least one screen comprising a plurality of elements for separating an image into a plurality of image elements, said screen being arranged on a focal-plane shutter and positioned to receive information from said objective; and means for transmitting information from said screen to at least one viewfinder so as to display therein a picture seens by said objective.
Claim 13
Dependent Claim 75 words
A camera comprising: a picture-taking objective capable of reproducing a plurality of elements to be photographed; at least one screen comprising a plurality of elements for separating an image into a plurality of image elements, said screen being arranged on a focal-plane shutter and positioned to receive information from said objective; and means for transmitting information from said screen to at least one viewfinder so as to display therein a picture seens by said objective.
Claim 14
Dependent Claim 122 words
A camera comprising: a picture-taking objective capable of reproducing objects to be photographed on a plane of a film; a shutter provided in a plane between the objective and the film plane; at least one screen comprising a plurality of elements for receiving and separating an image from the objective into a plurality of image elements, said screen being movable at least temporarily into a plane between the objective and the film plane without corresponding necessarily to the movement of the shutter, said screen plane being arranged in the axis of the light beam of the objective; and transmitting means for transmitting information from said screen to at least one viewfinder so as to display therein the picture seen by said objective.
Claim 15
Dependent Claim 122 words
A camera comprising: a picture-taking objective capable of reproducing objects to be photographed on a plane of a film; a shutter provided in a plane between the objective and the film plane; at least one screen comprising a plurality of elements for receiving and separating an image from the objective into a plurality of image elements, said screen being movable at least temporarily into a plane between the objective and the film plane without corresponding necessarily to the movement of the shutter, said screen plane being arranged in the axis of the light beam of the objective; and transmitting means for transmitting information from said screen to at least one viewfinder so as to display therein the picture seen by said objective.
