Fading audio-level controls for sound-recording motion picture cameras

In a motion picture camera, fade means for carrying out fade-out and fade-in operations, sound-recording means for recording sound during film exposure, adjustable means operatively connected with said sound-recording means for adjusting the audio level thereof, and control means operatively connected on the one hand to said adjustable means and on the other hand to said fade means for automatically controlling said adjustable means to reduce the audio level when a fade-out operation is carried out by said fade means and to increase the audio level when a fade-in operation is carried out by said fade means, said sound-recording means including an automatic means for automatically controlling the audio level during normal film exposure and sound-recording, and switch means electrically connected with said automatic means for rendering the latter ineffective during operation of said fade means.

In a motion picture camera, fade means for carrying out fade-out and fade-in operations, sound-recording means for recording sound during film exposure, adjustable means operatively connected with said sound-recording means for adjusting the audio level thereof, and control means operatively connected on the one hand to said adjustable means and on the other hand to said fade means for automatically controlling said adjustable means to reduce the audio level when a fade-out operation is carried out by said fade means and to increase the audio level when a fade-in operation is carried out by said fade means, said adjustable means being a photosensitive means for responding to light in order to adjust the audio level, light-source means positioned with respect to said photosensitive means for directing light to the latter, and said control means being situated between said light-source means and said photosensitive means for regulating the amount of light transmitted from said light-source means to said photosensitive means in response to operation of said fade means.
