An apparatus for playback of an analog optical sound track comprises a transport means for transporting a film including an analog optical sound track. A scanning means generates an image signal of only the analog optical sound track. An alignment means aligns the scanning means such that the image signal of the analog optical sound track substantially fills a width of the scanning means. A processor processes the image signal to form an audio output signal.
L'invention concerne un appareil permettant de lire une piste sonore optique analogique comprenant un moyen de transport permettant de transporter un film comprenant une piste sonore optique analogique. Un moyen de balayage permettant de générer un signal d'image uniquement de la piste sonore optique analogique. Un moyen d'alignement permettant d'aligner le moyen de balayage de sorte que le signal d'image de la piste sonore optique analogique remplisse sensiblement une largeur du moyen de balayage. Un processeur permettant de traiter le signal d'image pour former un signal de sortie audio.
