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).

Abstract: A code reader for reading an optical code is provided that has a linear image sensor having a plurality of linear arrangements of light reception pixels for recording image data having the code and a control and evaluation unit that is configured to locate and read the code in the image data, wherein the light reception pixels have a different spectral sensitivity. Here, at least one linear arrangement is a white line whose reception pixels are sensitive to white light for recording a gray scale image and the other linear arrangements are color lines whose reception pixels are sensitive to light of only one respective color for recording a color image.
