Abstract: A camera includes an image sensor having a first recording channel of a first sensitivity for recording first image data including first pixels and a second recording channel of a second sensitivity lower than the first sensitivity for recording second image data including second pixels. The first pixels and second pixels are associated with one another by capturing a same object area. A control and evaluation unit processing the image data is configured to suppress noise effects in the second image data using a noise suppression filter that assigns a new value to a respective considered second pixel based on second pixels in a neighborhood of the considered second pixel. The noise suppression filter takes the second pixels in the neighborhood into account with a weighting that depends on how similar first pixels associated with the second pixels are to the associated first pixel of the respective considered second pixel.

Abstract: A modular camera apparatus is provided having a common control and evaluation unit and having at least one camera module that has a reception optics and an image sensor that determine a module viewing zone of the camera module, wherein the module viewing zones together produce a monitored zone of the camera apparatus. The monitored zone is here adaptable by a common setting of the module viewing zones.

Abstract: An optoelectronic sensor is provided for a repeated detection of objects at different object distances, having a light receiver for generating a received signal from received light, having an evaluation unit for generating object information from the received signal, and having a distance sensor for determining the object distance from a respective object. The evaluation unit is here configured to acquire a measurement variable from the received signal with respect to an object, to associate the measurement variable with the object distance measured for the object, and to form a first distribution of the measurement variable via the object distance after detecting a plurality of objects.

Abstract: A method of reading an optical code is provided in which an image having the code is recorded, a first brightness adaptation of the image is carried out, a region of interest having the optical code is localized in the image, and the optical code in the region of interest is read. In this respect, the first brightness adaptation is a local brightness adaptation that is carried out in partial regions of the image still while further sections of the image are read; and the localization of the region of interest is based on image information of the image already processed by the first brightness adaptation.

Abstract: A method of determining the module size of an optical code (20) is specified in which image data having the code (20) are recorded and the module size is estimated from distances between light-dark transitions in the image data, At least one frequency distribution, in particular a histogram, is formed that indicates how often dark and/or light pixel sequences of a respective number occur along at least one line through the code (20) and the module size is estimated from the frequency distribution.
