The present invention relates to an apparatus (10) for determining respiration signals (R) from a subject (12), comprising: a receiving unit (28) for receiving image data (26) determined from the subject (12) in a field of view (42), a processing unit (30) for evaluating the image data (36), wherein the processing unit (30) is adapted to determine a plurality of different alternating signals (S) corresponding to vital sign information of the subject from a plurality of different areas (52, 54, 56) of the field of view (42) on the basis of movement pattern, and an evaluation unit (34) for evaluating the different alternating signals S and for determining a plurality of different respiration signals (R1, R2, R3) from the subject (12) on the basis of the different alternating signals (S) determined from the different areas (52, 54, 56) of the field of view (42).
