Reflection properties of the start/stop pattern, decoded codeword yield, unused error
correction, modulation, decodability, defects
In the
AIM DPM-1-2006
mode, a total of 8 characteristics are determined (for
ECC200 / QR
code
only):
Cell contrast, cell modulation, fixed pattern damage, decodability, axial non-uniformity (evaluation of
the width and height), grid non-uniformity (evaluation of the slope angle), unused error correction,
mean grey value of the light modules. (0,70..0,86 → A; 0,86..1,0 and 0,55..0,7 → B; 0,4..0,55 → C;
0,25..0,4 → D; under 0,25 → F).
NOTE
In order to be able to make the settings "Appearance" and "Code parameters" on the
tabs, you must set the Parameters on the "Common" tab to
User defined
.
Colour conversion:
Enter the method you wish to use to convert the field of view into a black and
white image here. Select
Gray value
, if the black and white version of the field of view contrasts well.
Select
Two colour optimization
if the barcode and background appear in similarly light colours.
Polarity:
Specify whether the code is brighter or darker than the background.
Mirroring:
Specify whether the code is mirrored.
Minimum contrast:
Specify the minimum contrast of the matrix code.
