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.
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:

Mirroring:
Specify whether the code is mirrored.
Minimum contrast:
