Abstract

APPAREIL DE PRISE DE VUES SUSCEPTIBLE D'ETRE ACTIONNE POUR ENREGISTRER UNE IMAGE D'UN SUJET PLACE DANS UNE GAMME DONNEE DE DISTANCES DE SUJET, L'APPAREIL DE PRISE DE VUES POSSEDANT UN TELEMETRE POUR, EN REPONSE A L'ACTIONNEMENT DE L'APPAREIL DE PRISE DE VUES, DETERMINER LA DISTANCE DU SUJET, ET UN AGENCEMENT D'OBTURATEUR POUR EXPOSER UNE IMAGE DU SUJET SUR UN MOYEN D'ENREGISTREMENT, LEDIT TELEMETRE PRODUISANT UN TRAIN D'IMPULSIONS DONT LE TOTAL EST EN RELATION AVEC LA DISTANCE DU SUJET. LE TELEMETRE PRODUIT UN TRAIN D'IMPULSIONS DE TELLE SORTE QU'UNE PLURALITE D'IMPULSIONS EST REPRESENTATIVE DE LA DISTANCE DU SUJET PLACE DANS LADITE GAMME ET QU'AU MOINS UNE AUTRE PLURALITE EST REPRESENTATIVE DE LA DISTANCE DU SUJET A L'EXTERIEUR DE LADITE GAMME, DES MOYENS ETANT DE PLUS PREVUS POUR INDIQUER QUE LE NOMBRE TOTAL D'IMPULSIONS SE TROUVE DANS LADITE AUTRE PLURALITE POUR AINSI DIRE QUE LEDIT SUJET EST A L'EXTERIEUR DE LADITE GAMME. APPLICATION A LA PHOTOGRAPHIE.PHOTOGRAPHIC APPARATUS CAPABLE OF BEING ACTIVATED TO RECORD AN IMAGE OF A SUBJECT PLACED IN A GIVEN RANGE OF SUBJECT DISTANCES, THE PHOTOGRAPHIC EQUIPMENT HAVING A TELEMETER FOR, IN RESPONSE TO THE OPERATION OF THE APPARATUS OF SHOOTING, DETERMINING THE DISTANCE OF THE SUBJECT, AND A SHUTTER ARRANGEMENT TO EXPOSE AN IMAGE OF THE SUBJECT ON A MEDIA OF RECORDING, A TELEMETER PRODUCING A TRAIN OF PULSES THE TOTAL OF WHICH IS RELATED TO THE DISTANCE OF THE SUBJECT. THE TELEMETER PRODUCES A TRAIN OF PULSES SUCH AS A PLURALITY OF PULSES IS REPRESENTATIVE OF THE DISTANCE OF THE SUBJECT PLACED IN THE SAID RANGE AND AT LEAST ONE OTHER PLURALITY IS REPRESENTATIVE OF THE DISTANCE OF THE SUBJECT OUTSIDE THE SUBJECT RANGE, MEANS BEING FURTHER PROVIDED FOR INDICATING THAT THE TOTAL NUMBER OF PULSES ARE IN THE SAID OTHER PLURALITY SO AS TO SAY THAT SUCH SUBJECT IS OUTSIDE THE SAID RANGE. APPLICATION TO PHOTOGRAPHY.
