9.4 Maximum Line Speed and Exposure Calculations

When the Dynamic reading option is selected in the Image Auto-Setup or Automatic Setup window, the maximum allowable
image exposure is automatically calculated according to the formula described in this section, using the parameters
entered.
The Exposure Time (or Shutter) parameter defines the time during which the image will be exposed to the reader to be
acquired. This parameter depends heavily on the environmental conditions (external lighting system, image contrast, etc.).
In general, a longer time corresponds to a lighter image but is susceptible to blurring due to the code movement; a shorter
exposure time corresponds to a darker image.
