摘要
The invention relates to a method and a device for detecting the opening angle of the shutter (light or dark sector) of an adjustable rotating shutter (1) arranged in a film camera. Said shutter comprises a circular-segment-shaped or circular-sector shaped shutter wing (2) which is driven by a shutter motor via a shutter shaft (20), and also comprises an adjustable shutter adjustment wing (3) arranged in a coaxial manner in relation to the shutter wing (2) and which can be displaced in relation to said shutter wing by means of a shutter adjustment wing motor (33). According to the invention, the position of the shutter wing (2) and the position of the shutter adjustment wing (3) are detected during a rotation of the rotating shutter (1) and the difference between the two positions forms a value for the shutter opening angle or the light or dark sector of the rotating shutter (1).
