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.
