Abstract: A camera for detecting an object in a detection zone is provided that has an image sensor having a plurality of light reception elements for the generation of image data from received light from the detection zone), a reception optics having a focus adjustment unit for setting a focal position, with an angle of incidence of the received light on the image sensor changing on a change of the focal position, and a control and evaluation unit that is configured to set the focal position for a sharp recording of image data of the object, A sensitivity change of the capturing of the image data caused by the respective angle of incidence of the received light is compensated.

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 camera (10) for detecting objects (32) moving relative to the camera (10) in a conveying direction (34), comprising a light receiver (20) having a plurality of pixels (24) arranged in two lines (22a-b) in a line direction transverse to the conveying direction (34) and an evaluation unit (26) configured to generate a first and second image (40a-b) of a partial region of the object (32) by means of the two lines (22a-b), the images (40a-b) having a mutual offset in the line direction, to compute an image line of higher resolution than an original resolution from the first and second image (40a-b), and to compose an overall image from the image lines generated in the course of the movement, wherein reception optics (16) are arranged in front of the light receiver (20) for providing the mutual offset.

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.
