method and device for automatic image acquisition of the face of a person

摘要

The method involves using a search camera (4), which detects a defined region of view with a large image angle. A portrait camera (8), which has a small image angle, detects a small field of view, within the field of view of the search camera. The portrait camera is guided with its field of view on a section of the field of view of the search camera. The field of view of the search camera is defined according to the presence of characteristics having at least a defined degree of coincidence with characteristics defined by reference data and which are typical of a view.
