<p>In order to continuously separate value documents from a value document stack (10), the value document stack is lifted and tracked to the separator (30). In order to control the tracking of the value document stack, an image of one side of the value document stack is taken and evaluated in order to recognize the edges of the individual value documents. The tracking of the value document stack is controlled on the basis of the number of value document edges which are detected in the image taken. If, however, the number of value document edges cannot be detected or can be detected only insufficiently, a brightness of the image in this image portion is also determined. When separating the value documents shown in this image portion, the tracking of the value document stack is controlled on the basis of the brightness detected in this image portion.</p> |
