Abstract
A portable slating device comprises a light-tight housing having a lens on the front thereof and a copyholder on the rear thereof. When the lens on the front end of the housing is positioned adjacent the lens of a movie camera whose scene takes are to be identified by slating information, the housing lens functions as a supplementary close-up lens cooperating with the camera lens to sharply focus the information in the copyholder onto the film in the movie camera. When the filming of a scene-take starts, the operator closes a switch for simultaneously energizing a synchronizing light bulb located within the housing and an audio signal device mounted on the housing to provide for synchronizing the visual action of the film with the sound track.
Claims8
A portable slating device for use with a movie camera having a lens, a film, and a separate sound recorder, said device comprising:
- a light-tight housing having a lens on the front end and a copyholder on the back end thereof for holding an opaque record medium having information on the face thereof of a size as provided by a conventional typewriter,
- a source of electrical energy,
- light bulbs in said housing connected to said source of electrical energy and positioned for illuminating the face of the record medium so that the information thereon can be photographed,
- a synchronizing light bulb located in said housing,
- an audio signal means mounted on the wall of said housing, and
- circuit means connected to said source of electrical energy and including a switch attached to the wall of said housing which when closed provides for momentarily simultaneously energizing said synchronizing light bulb and said audio signal means,
- whereby when the front end of said housing is positioned adjacent the lens of the camera operating at sound speed for the housing lens functions as a supplementary close-up lens which cooperates with the camera lens to sharply focus the information on the opaque record medium onto the film, and
- whereby when said switch is closed said synchronizing light bulb flashes on a frame of the film and said audio signal means emits an audio signal which is recorded by the sound recorder for use in thereafter synchronizing the visual action on the film with the audio on the sound recorder.
