摘要： A method is disclosed whereby film images designed to produce a high-impact effect upon the members of an audience viewing a motion picture film are composited with other images designed to provide the conventional cinematic effect upon such audience members. 'High-impact' film images (21-23) photographed at forty-eight of fifty frames per second are composited with 'conventional' images (11-13) photographed at the traditional motion picture rates of twenty-four or twenty-five frames per second, with such images superimposed onto the same film frame. Certain portions of the motion picture image (31-33) seen by the audience deliver a greater illusion of reality than other portions of the same motion picture image. In addition, the method described can accommodate the intercutting of discrete scenes presenting either high-impact or conventional cinema experience. The method disclosed here also allows easy conversion of films of the 'conventional' twenty-four or twenty-five frames per second rate associated with conventional motion picture release and exhibition.

摘要： The present invention relates to film transport systems for motion picture projectors and, more particularly, to a film projector movement that is capable of transporting film prints having frames spanning a predetermined number of perforations per frame at a specified projection frame-rate and then automatically switching to another film format having frames spanning a different number of perforations per frame as well as a different projection frame-rate, based on the detection of an encoded trigger strip on the film which carries the format characteristics of the incoming film. A controller enables the system to automatically switch between a variety of different film formats and frame-rates, on the same projector and on the same platter of film, without substantially interrupting or delaying operation of the projector.

摘要： A device for controlling and adjusting film-strip feed in a film projector comprises reels (62, 72), each driven by a motor (61, 72) and arranged on either side of a film gate (8); feed and take-up sprockets (3, 4) driven by at least one drive motor (S1) and arranged between the reels (62, 72) and the film gate (8), which produce film loops on either side of the film gate (8); and a film-strip feed device (2) between the feed and take-up sprockets (3, 4). The drive motors (21; 51; 61, 71) for the reels (62, 72), the feed and take-up spockets (3, 4) and the film-strip feed device (2) are connected to a sensor device (25; 55; 65, 75) which determines the speed and/or direction of rotation. If a predetermined speed and/or direction of rotation of at least one of the drive motors (21; 51; 61; 71) are not respected and at least one drive motor rotates in a direction of rotation contrary to a direction of rotation predetermined by a priority control system, then all the drive motors (21; 51; 61, 71) are braked simultaneously.

摘要： A switchable pulldown film projection system comprising a film transport system (10) for transporting film (12) through a projector (14). The film transport system (10) has a plurality of sprockets (22, 24 and 28) teeth for engaging perforations (56) on the film (12), and a pair of motors (30 and 32) that rotate the sprockets (22, 24 and 28) and move the film (12) in a frame-by-frame manner with respect to an aperture (29) in the projector (14). The motors (30 and 32) are controlled by an electronic controller (94) that changes the rotational output of the motors (30 and 32) based on a signal (104) related to the format of the film (12) in terms of the number of perforations (56) spanned by each frame (58) on the film (12). The controller (94) enables the system (16) to switch between a variety of different film formats, on the same projector (14) and on the same strip of film (12), without substantially interrupting or delaying operation of the projector (14).

摘要： Un agencement d'avancement de film permet d'appliquer un procédé d'avancement intermittent ou continu du film. L'agencement comprend un moteur d'entraînement dont l'arbre est relié d'une part à une bobine dentée qui s'engage dans au moins une rangée de perforations du film et d'autre part à un capteur angulaire qui transmet des signaux de positionnement correspondant à la position angulaire de l'arbre du moteur à un agencement de commande et de réglage dont la sortie commande le moteur d'entraînement au moyen d'un amplificateur à courant continu. Lors de l'avancement intermittent du film, chaque étape d'avancement d'images successives est subdivisée en au moins une phase d'accélération, une phase de ralentissement et une phase de réglage de la position. Ces phases présentent une longueur variable, de préférence ajustable ou programmable, l'accroissement des valeurs de consigne de l'accélération et du ralentissement de l'agencement d'avancement du film étant limité.

摘要： A web motion control system (50) for controlling the tension in a web (10) advanced at a preset velocity in a web transport path between a supply reel (22) and a take-up reel (32) without the use of tension loops, particularly for use in transporting spliced together, developed filmstrips through a film preparation work station. The web (10) (film) is advanced in the web transport path in either a forward or rewind direction in either a velocity mode or a position mode by a motor driven capstan roller. The supply and take-up reels (22, 32) have a hub over which the web (10) is wound in unknown supply and take-up web winding diameters. Take-up and supply reel motors and encoders are attached to the take-up and supply reels (22, 32) for imparting torques to the reels in response to motor torque signals to prevent slack in the film segments between the reels and the capstan roller and to provide reel encoder output signals on at least each 360° rotation of the reels. A metering encoder rotated with the capstan roller is employed to develop an encoder count signal. The web winding radii are calculated from the differential encoder counts at successive reel encoder output signals, and appropriate motor torque signals are developed. The encoder count is also employed in the position mode to control the stopping of the web (10) after a predetermined advancement.

摘要： Un agencement de commande et de réglage de l'avancement du film dans un projecteur de cinéma comprend des plateaux d'enroulement (62, 72) agencés des deux côtés d'une fenêtre de cadrage (8) et susceptibles d'être entraînés par leur propre moteur (61, 71), un galet supérieur et un débiteur inférieur (3, 4) agencés chacun entre un plateau d'enroulement (62, 72) et la fenêtre de cadrage (8) et susceptibles d'être entraînés par au moins un moteur d'entraînement (51) afin de créer des boucles de film des deux côtés de la fenêtre de cadrage (8), et un organe (2) d'avancement du film situé entre le galet supérieur et le débiteur inférieur (3, 4). Les moteurs d'entraînement (21; 51; 61, 71) des plateaux d'enroulement (62, 72), du galet supérieur et du débiteur (3, 4) et de l'organe (2) d'avancement du film sont reliés à un capteur (25; 55; 65, 75) de la vitesse de rotation et/ou du sens de rotation. Lorsque la vitesse de rotation et/ou le sens de rotation prédéterminés d'au moins un moteur d'entraînement (21; 51; 61, 71) ne sont pas respectés et qu'au moins un moteur d'entraînement tourne dans un sens inverse à celui prédéterminé par une unité de commande prioritaire, tous les moteurs d'entraînement (21; 51; 61, 71) sont freinés en même temps.
