An optoelectronic code reading apparatus is provided that has at least one camera-based code reader having an image sensor for recording image data from a reading zone, that has a control and evaluation unit that comprises a decoding unit for locating code zones in the image data and for reading their code content, and that has a filter unit to determine whether a multiple reading has taken place in which a plurality of codes were read. In this respect, the filter unit is furthermore configured to check the geometry of the code zones in the case of a multiple reading to identify a valid code.
