Abstract
The method for automatic regulation comprises the steps of: acquiring an image; attempting reading of at least one optical code in the acquired image; detecting characteristic quantities of the acquired image only if the reading has been successful; and carrying out a large number of acquisitions of different images, obtaining a significant statistical datum of the characteristic quantities. The controlled parameters of the optical system are modified on the basis of this statistical datum detected, to optimise the reading. If the relationship between each controlled parameter and the respective characteristic quantities is not monotonic, the current valve of the controlled parameter is modified by at least one small positive deviation and one small negative deviation with respect to the current value; the value of the controlled parameter providing the best reading then becomes the central value for the successive readings.
