Abstract: A method of reading an optical code is provided in which a brightness profile of the code is recorded, light and dark part regions are identified in the brightness profile, and the code content of the optical code is read, First sum measurements for the light quantity in the respective light part regions and second sum measurements for the light quantity lacking for a white level in the respective dark part regions are determined from the brightness profile and the code content is read based on the first and second sum measurements.
