Abstract

A camera based code reader is provided that has an image sensor for detecting image data having an optical code, a memory for storing image data, a first processing unit for transmitting the image data from the image sensor to the memory in an image data stream, and a second processing unit that is configured for a decoding in which the stored image data are evaluated to read the code content of the optical code, In this respect, the first processing unit is configured for at least one auxiliary function in which the first processing unit reads back at least some of the image data from the memory and writes a pre-processing result back to the memory; and in that the second processing unit is configured to invoke the auxiliary function of the first processing unit as required to assist the decoding.
