Abstract: A synchronization device for providing an optical synchronization signal in computer controlled picture recordings of a motion picture camera is provided. The synchronization device includes a signaling device for generating an optical synchronization signal, whereby the optical synchronization signal of the synchronization device is triggered by a computer that controls the picture recordings. By providing a number of optical signaling elements, the signaling device is configured to provide different optical signals for synchronizing the picture recording of the motion picture camera.

Abstract: A support stage for a prompter has a bi-divisional structure comprising a first support stage on which an LCD and a semitransparent mirror are supported and a second support stage on which an ENG camera is supported. Because the first support stage and the second support stage are constructed in the manner as to be capable of overlapping with each other by a slide mechanism, the support stage can be compact in size and can have a better weight balance; hence the support stage is easy to carry.

Abstract: The present invention is a prompter for TV camera allowing it to easily mount a half mirror on a manuscript display with an image memory. The apparatus comprises a support plate swingably supporting the half mirror, operating knobs for securing the half mirror at its operating position and retracted position, and a light shield for shielding the half mirror therearound when the half mirror is positioned in front of the lens assembly, and being foldable. The support plate is mounted on the display unit by mating the half hinges, or by coupling with magnets. When the half mirror is inclined by 45.degree. to its operating position, the image of manuscript is displayed on the half mirror. In retracting, the half mirror is moved to the retracted position and the light shield can be folded.

Abstract: A personal use, low cost, portable speech prompter which is light in weight and small in size. The speech prompter includes a support frame on which is mounted a light box with a horizontal translucent top wall. A transparent film with a speech printed thereon is slidably mounted, upside down, on the light box top wall. An image of the speech printed on the transparent film is reflected upwardly to a see-through view screen which reflects the speech image rearwardly along a line of sight between a speaker and the see-through view screen.

Abstract: The element of the laser framefinder comprise a laser beam generator, a shutter for pulsing a beam of laser light, a laser beam scanner, coupling elements joining a laser beam generator with a laser beam scanner, elements for manipulating a scanning device to produce a laser light pattern, a camera including elements for coupling a scanning device to a camera body, projecting device for aligning a laser light pattern with an optical axis of a camera, a device for optically transmitting a laser light pattern from the scanner to one projecting device, elements creating optical transparency to laser light in a substantially planar ground glass element used as the focusing element of a reflex viewing system, a feedback network utilizing a sensing element to couple laser beam pulsation with a positioning of an optical element of a scanning device, a feedback network utilizing a sensing device to couple a laser beam pulsation with a positioning of a projecting apparatus.

Abstract: Cinematography under low visibility conditions is facilitated by providing a camera with a slide that has photoengraved markings in the ocular path for indicating the borders of the camera field, light emitting diodes for lighting an edge of the slide, and logic circuitry that energizes the light emitting diodes in synchronism with the rotation of the camera shutter so that the light emitting diodes are energized when the shutter is closed.

Abstract: A system for performance of photographing with moving picture cameras, still picture cameras or television cameras, particularly of direct sound - movie picture photography, whereby a signal receptor - and/or transmitting - device is coordinated to each photographic object, and the running time between the photographic object, and respectively, between the signal receptor - and/or transmitting - device and the camera is used for determining the distance of the photographic object from the camera and under the circumstances for the automatic distance setting of its camera taking lens.

Abstract: An audio signal device for reproduction apparatus such as a sound-film camera including a sound signal emitter and a microphone connected to the camera in which the control trigger on the camera is arranged through a switching arrangement to connect the sound emitter to the microphone only during at least one of the turn-on and turn-off steps in the operation of the camera to thereby provide an audible signal from the microphone to the person being photographed only during such steps.

Abstract: A combination prompting device (such as a known roll type or a video monitor used as a prompter) and a television camera, together with a reflecting system, including two transparent or pellicle mirrors (or clear glass or plastic sheets), in periscope embodiments, angularly mounted on said camera, one being disposed in front of the lens, substantially angled, such as at about 45.degree. to the longitudinal axis thereof, whereby an actor in front of the camera looking in the direction of the camera lens can see a reflected script or picture of himself and/or other scenes related to the program exhibited on the screen of the prompting device.

Abstract: An automatic prompter uses a script written on a paper-supply roll that is fed across a reading region and coiled in a takeup roll, and a motor drives the feed mechanism in pace with the speaker reading the script. A microphone picks up the speaker's speech, and electronic circuitry amplifies the speech and detects the portion of the speech that exceeds a threshold. Switching circuitry energizes the motor whenever the speech is above the threshold and de-energizes the motor whenever the speech is not above the threshold. The drive train, including the motor and the feed roller, has mechanical inertia that cooperates with the switching circuitry so that the motor increases speed during energization up to a maximum limit and decreases speed after de-energization to provide an average speed as a function of the portion of the total time of a given interval that the energization occurs.
