Definition:
|
All the pixels that fall within the area of
the test symbol, including its required zone, will be sorted by
their reflectance values to select the darkest 10% and the lightest
10% of the pixels. The arithmetic mean of the darkest and the
lightest pixels is calculated and the difference of the two means
is the Symbol Contrast.
(ANSI) Symbol Contrast grading is defined
this way:
|
| |
A (4.0) if SC > 70%
C (2.0) if SC > 40%
F (0.0) if SC > 20%
|
|
B (3.0) if SC > 55%
D (1.0) if SC > 20%
|
| |
If enabled, the symbol contrast is appended
to the symbol data according to the ISO/IEC 16022 Symbol Quality Output Mode
setting.
