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

1. 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.

2. 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.

3. 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.

4. 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.

5. 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.

6. A camera, as defined in claim 4, wherein said screen is an integral part of at least one curtain of a focal-plane shutter.

7. 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.

8. 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.

9. 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.

10. 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.

11. 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.
