Minimum values for image acquisition, decoding and verification
Note
Specifying the acquisition interval
According to the sampling theorem, the acquisition interval should be selected so that the
code to be read can be decoded mathematically with two acquired images.
Note
Dependence on the actual achievable values
The actual achievable values depend on the lamp used and the maximum exposure time
currently set. The WBM shows the actual high and low limits for each of the parameters
affected by this.
