Document Type and Number:
Japanese Patent JPS5056937
Kind Code:
A
Abstract:
A method and apparatus for the resynchronization of the transport of movie film (image carrier) with the movement of another information-carrying medium such as sound tape film. Speed control and synchronization signals are produced by means of sensing the sound tape movement which provides control synchronization signal, monitoring the image frames for each sequence on the movie film by means of a counter, and comparing in a coincidence circuit the image frame count signal with the signal from the sound tape. Desynchronization of the movie film and tape is indicated by the absence of a predetermined relationship between the number of image frames in a given sequence and the signal from the sound tape, whereupon the coincidence circuit energizes an appropriate control means via a switching mechanism, such as a gate circuit, which produces a resynchronization of the film and the sound tape.
