Sound modulating control display system for cine camera - has light producing devices in viewfinder illuminated when sound levels are reached

摘要

A sound control display device for sound film cine cam with the display mounted in the viewfinder of the camera is constructed using several lighting elements the illumination of which is directly related to the peak values of the sound modulating control. Light emitting diodes or liquid crystals may be used as the lighting elements. Circuitry is used which connects the light units of the display system to the sound control device and which permits the appropriate lighting unit of the display to be illuminated when the specific sound peak value for that unit is reached.
