Abstract
A film camera is disclosed which is equipped with a device for recording synchronizing data, for use in automated post processing, wherein, for example, timing data is exposed onto the film by means of an optical display element activated by an activator unit and with a rotary shutter positioned so that at a first half rotation of the shutter the light entering through the camera objective is deflected through the viewfinder and during the second half rotation of the shutter the light enters an image window and wherein the activator unit comprises a shutter drive which controls the actuation of the shutter over which the rotating shutter is held in an arrested position covering the image window during exposure of the film by the optical display element.
Claims20
A film camera, comprising recordation means for recording data onto a film during exposure of the film in the camera over a predetermined time period, said recordation means including:
- an activator,
- an optical display element operated by the activator for exposing a film to form first data thereon relating to film information, and
- a time code generator operatively connected to the optical display element for exposing the film, cadre-by-cadre, via the optical display element to form second data thereon relating to time-dependent information in directly readable or coded form.
A method for recording information onto a film in a film camera, comprising the steps of providing an optical display element for displaying information, exposing a film, cadre-by-cadre, to thereby form current time information, displayed by the optical display element, in directly readable or coded form on the film before each film sequence.
A method for synchronizing a film sequence with a sound recordation, comprising the steps of:
- exposing a film at the start of a film recordation by a recordation device to form a time information in directly readable or machine-readable coded form on the film;
- and
- developing a negative of the film;
- scanning the time information contained in single frames on the film by a reader.
