A method for detecting optical codes comprises an input image being provided. Optical codes in the input image are detected by generating an output image on the basis of the input image. Within generating the output image, pixels of an area of the input image comprising a part of an optical code are assigned a first intensity in the output image. Within generating the output image, pixels of an area of the input image e.g. comprising no part of an optical code are assigned a second intensity in the output image. Regions of the output image with the first intensity are provided for determining properties of the detected optical codes.

Method, automation system and computer system for detecting optical codes

In a real-time environment at least one task is executed with a pre-defined task run-time, wherein at least one auxiliary function with indeterminate function run-time is to be processed within the specified task run-time by means of a time monitoring function. The time monitoring function, which defines a termination time for the auxiliary function within the pre-defined task run-time, is started. Then the auxiliary function is executed, wherein the time monitoring function monitors the function run-time and a function abort is initiated if the pre-defined abort time point is exceeded. Finally, the time monitoring function is terminated.
