ISO/IEC 15415 Symbol Quality Output
Contrast
Definition:
Contrast measurements assume 8-bit 0 to 255 grey correlate to 0 to
100% reflectance. Contrast is calculated in accordance with the ISO
15415 specification. The Contrast grading is defined as follows.
A (4.0) if C
B (3.0) if C
C (2.0) if C
D (1.0) if C
F (0.0) if C
When enabled, the Contrast is attached to the symbol output data as a
value.
Serial Cmd:
<K725, aperture, overall, contrast, modulation, reflectance margin, fixed
pattern damage, axial non-uniformity, grid non-uniformity, unused ECC>
Default:
Disabled
Options:
0 = Disabled
Modulation
Definition:
Modulation is calculated in accordance with the ISO 15415 specifica-
tion.
The Modulation grading is defined as follows.
A (4.0) if MOD
B (3.0) if MOD
C (2.0) if MOD
D (1.0) if MOD
F (0.0) if MOD
When enabled, the Modulation is attached to the symbol output data as
a value.
Serial Cmd:
<K725, aperture, overall, contrast, modulation, reflectance margin, fixed
pattern damage, axial non-uniformity, grid non-uniformity, unused ECC>
Default:
Disabled
Options:
0 = Disabled
Reflectance Margin
Definition:
Reflectance Margin is calculated in accordance with the ISO 15415
specification.
When enabled, the Reflectance Margin is attached to the symbol output
data as a value.
Serial Cmd:
<K725, aperture, overall, contrast, modulation, reflectance margin,
fixed pattern damage, axial non-uniformity, grid non-uniformity, unused
ECC>
Default:
Disabled
Options:
0 = Disabled
