Abstract: A camera (10) for the detection of objects (30) in a detection region (16) is provided which has a light receiver (22) having a plurality of light reception pixels, a multispectral illumination unit (12) for illuminating the detection region (16) in different spectral bands and an evaluation unit (24) that is configured to illuminate the detection region (16) by means of the illumination unit (12) during different illumination windows of time (30a-c) in a respectively different spectral band and to record image data from the detection region (16) by means of the light receiver (22) in recording windows of time (40a-c, 42a-c). In this respect, the light receiver (22) is configured as a two-line receiver having a first line (22a) of light reception pixels and a second line (22b) of light reception pixels and the recording window of time (40a-c, 42a-c) for the first line (22a) is different from that for the second line (22b).
