Definitions

  • the cinematography presupposes as essential condition that property of the human eye that is called " persistence of the images on the retine".
  • This phenomenon of inertia of the image on our retine gives in the cinematography the sensation of movement by means of a determined sequence of images projected on a screen: images before registered at intervals of time between the one and the other, inferior to 1/16 of second and made them slide on a pellicle or film in which are printed the instantaneous whales, settled frames that by the overlapping, give the sensation of the moviment if made slide on a tape, by a frequency like to that one in which had been unrolled in the movie film camera.
  • movie film cameras capable to be able to go on with speed, so that to be able to uncouple the frames, therefore with a speed of sliding very elevated, but perhaps, even if possible, with a damage of the quality of the same images, qualitative, with consequent results in the projection.
  • wc can say monotrack and with a frequency of retake that vanes from n 20 to 30 frames at second

Abstract

L'invention concerne un système cinématographique dans lequel le film est exposé avec au moins deux pistes d'images parallèles, les images des pistes voisines étant déplacées dans le sens longitudinal de l'ordre de moitié ou du tiers de la hauteur des images. Les images sont exposées en alternance, de manière à ce que les images le long d'une ligne en zigzag traversant le film soient exposées en séquence temporelles. Les images d'un film à pistes doubles peuvent être fusionnées, recombinées sur un film à piste unique pour une projection à vitesse réduite. Alternativement, une paire de caméras à obturateurs synchronisées peut être utilisée pour exposer deux films à piste unique d'images pour une projection à vitesse réduite. Ce système permet une surveillance constante d'une scène cinématographique et réduit les effets stroboscopiques et de scintillement en cours d'enregistrement d'objets se déplaçant rapidement.
