1 . A self-service terminal ( 100 ), comprising:
an imaging device ( 102 ), configured for providing at least one digital image ( 104 );
at least one processor ( 110 ), configured for:
determining whether the at least one digital image ( 104 ) comprises a face of a person;
if the at least one digital image ( 104 ) comprises the face of the person, cutting out from the at least one digital image ( 104 ) an image region which comprises the face of the person; and
a storage device ( 108 ), configured for storing the image region.
2 . The self-service terminal ( 100 ) as claimed in claim 1 , wherein the at least one processor ( 110 ) is furthermore configured for: discarding the at least one digital image ( 104 ) if the at least one digital image ( 104 ) does not comprise a face of a person.
3 . The self-service terminal ( 100 ) as claimed in either of claims 1 and 2 , wherein the at least one processor ( 110 ) is furthermore configured for:
if the at least one digital image ( 104 ) comprises the face of the person, determining whether the cut-out image region satisfies a predefined criterion; and
storing the image region only if the cut-out image region satisfies the predefined criterion.
4 . The self-service terminal ( 100 ) as claimed in claim 3 , wherein the at least one processor ( 110 ) is furthermore configured for: discarding the image region if the cut-out image region does not satisfy the predefined criterion, or wherein the at least one processor ( 110 ) is configured for: selecting the image region using an image quality assessment and storing the selected image region.
5 . The self-service terminal ( 100 ) as claimed in either of claims 3 and 4 , wherein the predefined criterion comprises a predefined image quality criterion of the image region and wherein the predefined image quality criterion optionally comprises at least one of the following parameters: sharpness, brightness, contrast.
6 . The self-service terminal ( 100 ) as claimed in any of claims 3 to 5 , wherein the predefined criterion comprises a predefined recognizability criterion comprising the recognizability of the face of the person in the image region, and wherein optionally the recognizability criterion comprises at least one of the following parameters: degree of concealment of the face, viewing angle.
7 . The self-service terminal ( 100 ) as claimed in any of claims 1 to 6 , wherein the self-service terminal ( 100 ) is an automated teller machine, a self-service checkout or a self-service kiosk.
8 . The self-service terminal ( 100 ) as claimed in any of claims 1 to 7 , wherein the storage device ( 108 ) is configured to store the image region of the at least one digital image ( 104 ) in an image database.
9 . The self-service terminal ( 100 ) as claimed in claim 8 , wherein the storage device ( 108 ) is furthermore configured for storing a time of day at which the image was detected by means of the imaging device ( 102 ) and/or a procedure number assigned to the image region in conjunction with the image region in the image database.
10 . The self-service terminal ( 100 ) as claimed in any of claims 1 to 9 , wherein the at least one processor ( 110 ) is configured for determining whether the at least one digital image ( 104 ) comprises a face of a person by means of a facial recognition algorithm.
11 . The self-service terminal ( 100 ) as claimed in any of claims 1 to 10 , wherein the at least one digital image ( 104 ) is a sequence of digital images.
12 . The self-service terminal ( 100 ) as claimed in claim 11 , wherein the processor ( 110 ) is configured to process the sequence of images and to provide a sequence of image regions, and wherein the storage device ( 108 ) is configured to store the sequence of image regions.
13 . The self-service terminal ( 100 ) as claimed in any of claims 1 to 12 , wherein the storage device ( 108 ) comprises a non-volatile memory for storing the image region of the at least one digital image ( 104 ).
14 . A method for operating a self-service terminal ( 100 ), comprising:
detecting at least one digital image ( 104 );
determining whether the at least one digital image ( 104 ) comprises a face of a person;
if the at least one digital image ( 104 ) comprises the face of the person, cutting out from the at least one digital image ( 104 ) an image region which comprises the face of the person; and
storing the cut-out image region of the at least one digital image ( 104 ).
15 . The method as claimed in claim 16 , wherein the cut-out image region of the at least one digital image ( 104 ) is stored in a non-volatile memory.
