Abstract

A method for obtaining a composite color picture out of a plurality of original pictures and a camera employing the method are disclosed, wherein a plurality of original color picture are selectively exposed on a sheet of film one by one in a sequential manner with appropriate color compensation, magnification or reduction in size, and proper masking conducted upon each exposure. Both photographic film on which to duplicate composite picture and the original pictures are displaced across and on the optical center line of a camera in such a manner that, on the composite photographic picture thus obtained, the original pictures are laid out according to a plan.

Dependent claims

A duplicating camera for producing a color composite picture out of a plurality of original color pictures with a desired layout arrangement, comprising,

an original picture frame holding a plurality of original color pictures side by side on a single plane,
an original picture carriage supporting the original picture frame in a direction perpendicular to the plane on which the original pictures are mounted,
rotation means for rotatably supporting said frame at corners thereof to permit rotation of said pictures about an axis normal to said plane,
a means for successively moving the original picture frame across the optical center line of the duplicating camera, said rotation means supporting said moving means and being configured for clearance of said moving means to permit independent operation of said rotation means and said moving means while said original picture is oriented normally to said axis,
a light source for illuminating the color original picture which is placed on the optical center line,
a lens carriage comprising an optical system for producing the image of the original picture which is placed on the optical center line of the camera on its focal plane,
an exposure control device,
a cabinet which supports photosensitive material on the focal plane of the duplicating camera in such a manner that a desired point on the photosensitive material may be aligned on the optical center line of the duplicating camera for each of the original pictures,
a masking device having a variable light transmitting area over the photosensitive material surface having the lens carriage,
the masking device being provided with a light shielding screen which may be extended to or retracted from the central portion of the masking device on each side of the frame of the masking device,
the forward end of the light shielding screen being provided with a flat bar having knife edges, each pair of the neighboring flat bars with knife edges being slideably engaged one over another with their broader surfaces contacting back to back, and
a color compensating means adapted to be selectively actuated for each of the original pictures.

there being a plurality of original color pictures placed on said original picture frame, side by side, said original picture frame being detachably mounted on the original picture carriage,
a plurality of original picture frames being successively replaced from one to another upon completion of picture taking with respect to each of the original picture frames,
each of the original picture frames being provided with indicator means while the original picture carriage is provided with a detector means which is adapted to cooperate with the indicator means for the identification of the original picture which is presently mounted on the original picture carriage, and
wherein the indicator means comprises an indicator holder having a plurality of cells in which indicators are placed selectively in number and arrangement while the detector means comprises the same number of detectors as the cells in the indicator means arranged on the original picture carriage in such a manner that each of the detectors opposes a corresponding one of the cells in the indicator holder one to one.
