Abstract
Abstract 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.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
257 words
In an apparatus for reproducing motion pictures recorded on a recording medium, in combination, reproducing means operative for reproducing successive image frames on the recording medium, including transport means for transporting the recording medium through the apparatus; and interrupt-transport marking detector means operative for detecting interrupt-transport frame markings on the recording medium correlated with certain image frames and in response to such detection causing the transport means to discontinue recording medium transport so that the reproducing means reproduces those image frames as still images, the marking detector means being adapted to detect both end-of-scene interrupt-transport frame markings correlated with the terminal frames of motion-picture scenes and still-shot interrupt-transport frame markings correlated with recorded still shots, the marking detector means including discriminating means for discriminating between end-of-scene and still-shot interrupt-transport frame markings and selecting means for selecting the interrupt-transport markings to be detected, the discriminating means comprising means for discriminating between a first case in which a frame provided with an interrupt-transport frame marking is not preceded by a frame provided with an interrupt-transport frame marking, and a second case in which a frame provided with an interrupt-transport frame marking is preceded by a frame provided with an interrupt-transport frame marking, the detector means comprising two marking detectors spaced apart in the direction of recording medium transport a distance corresponding to one image frame, the discriminating means comprising means for differentiating between the case wherein both marking detectors detect interrupt-transport frame markings and the case wherein only one of the two marking detectors detects an interrupt-transport frame marking.

In an apparatus for reproducing motion pictures recorded on a recording medium, in combination, reproducing means operative for reproducing successive image frames on the recording medium, including transport means for transporting the recording medium through the apparatus; and interrupt-transport marking detector means operative for detecting interrupt-transport frame markings on the recording medium correlated with certain image frames and in response to such detection causing the transport means to discontinue recording medium transport so that the reproducing means reproduces those image frames as still images, the marking detector means including a magnetic pick-up head for detecting magnetically recorded interrupt-transport frame markings and also further magnetically recorded markings distinguishable from the interrupt-transport frame markings, furthermore including means receiving signals from the pick-up head and storing information concerning the interrupt-transport frame markings, means for erasing both the interrupt-transport frame markings and the further markings, and means for rerecording the erased interrupt-transport frame markings onto the recording medium.
