Restoration of audio information embodied on a soundtrack (25) of a motion picture film (20) advantageously occurs by scanning the film with a beam of light to capture the image in the form of a digital signal via an imager (100). The digital signal undergoes storage in a storage mechanism (300) and subsequent processing via controller (400). The controller (400) applies one or more statistical processing algorithms to eliminate deficiencies and to enhance the quality of the audio embodied in the soundtrack.
La présente invention permet la restauration avantageuse d'informations audio contenues dans une bande son (25) d'un film cinématographique (20) par balayage du film à l'aide d'un faisceau de lumière afin de capturer l'image sous la forme d'un signal numérique via un imageur (100). Le signal numérique est stocké dans un mécanisme de conservation en mémoire (300) et subit un traitement ultérieur effectué par un contrôleur (400). Le contrôleur (400) applique au moins un algorithme de traitement statistique afin d'éliminer les défauts et d'améliorer la qualité de l'audio contenu dans la bande son.
