The invention concerns a method of, and an apparatus for, photographically making positive pictures from individual frames of motion-picture films, film strips and microfilms. The image from a respective selected film frame is exposed onto a self-developing ('instant-picture') film sheet which is then developed to produce a positive paper picture of this image.

Method of, and apparatus for photographically making positive pictures

The reproducing apparatus, such as a motion-picture film projector, stops recording medium transport in response to interrupt-transport frame markings on the recording medium and reproduces the thusly marked image frames as still images. Interrupt-transport frame markings are provided at the terminal frame of each motion-picture scene on the recording medium, or at each still-shot image frame on the recording medium, or both. The user of the reproducing apparatus can select automatic reproduction of motion-picture scenes interspersed with automatic still reproduction of still shots, and can additionally select automatic still reproduction of the terminal frame of each motion-picture scene.

Reproducing of interspersed motion-picture scenes and still shots

The user of a motion-picture camera selects between motion-picture and single-exposure operation, and presses a release member to initiate shooting, letting go of it to terminate motion-picture shooting. Each time the user lets go of the release member, an internal device provides an interrupt-transport marking alongside the just exposed film frame, or phase shifted relative thereto. Alternatively, the interrupt-transport marking is provided the next time the user presses the release member. In this way, the terminal frame of each motion-picture scene, and each and every one of the interspersed single-exposure shots, is provided with an interrupt-transport frame marking. Thus, if the film is run through a reproducing apparatus provided with a marking detector, detection of each interrupt-transport marking during motion-picture reproduction causes the terminal frame of each motion-picture scene, and also each one of the still shots, to be persistently reproduced as a still image. The interrupt-transport markings could alternatively be provided by such a device in a reproducing apparatus.
