    Abstract: The invention relates to a device and a method for reproducing photographic sound information in double-edged variable-width track (DZ). An opto-electronic converter device (1, 2, 4, 9 to 13) scans the optical sound track (3) of a film (4). Said converter device (1, 2, 4, 9 to 13) produces a digital image signal for intermediate storage in the memory (19) of a program-controlled data processing device (15). Said data processing device (15) derives the course of the two edges of the double-edged variable-width track (DZ) from data values of the intermediately stored image signal. Audio data for reproducing sound are generated using data relating to the course of the edges that is determined.

    Abstract translation: 为了以双Z字形(DZ)重放轻音信息,光电换能器装置(1,2,4,9至13)扫描胶片(4)的光声道(3)。 转换器装置(1,2,4,9至13)产生用于中间存储在程控数据处理装置(15)的存储器(19)中的数字图像信号。 在被缓存的图像信号的数据值中,数据处理装置(15)导出双锯齿签名(DZ)的两个边的走向。 基于关于所确定的边缘曲线的数据,生成用于声音再现的音频数据。
