Image processing
3.1 Code reading (1D/2D codes)
Range of application
● Different types of code can be read in an image.
● Available for data matrix codes that can be read with standard methods.
● The maximum number of codes and the code types used are specified when the program
is saved. Depending on the configuration, the actual number and the code types found in
processing mode can vary.
● Due to the multiple decoding, the processing time is extended approximately proportional
to the number of codes per image.
Example
With this function, you can record a one-dimensional code and a data matrix code on
packaging with one image acquisition and output the read result of both codes in the same
cycle.
