Description
JG Judgment
−
2: No judgment (not measured)
0: Judgment is OK
−
1: Judgment is NG
−
16: Measurement timeout error
This is the judgment result.

2: No verification pattern or reading
error
−
1: Verification is NG
0 to 31: Master data No
The verification result (master data No.) is out-
put.
N
Num. of characters
0 to 1024
The number of characters read is output.
E
Cell recognition rate
0 to 100
Value that lets you check the correction rate.
The recognition rate is higher when the ratio of
corrected characters to the total number of
characters in the code is lower.
When a code cannot be read, the value is 0.
C
Contrast
0 to 100
Indicates the contrast in a code.
When the difference of contrast between light
and shade in a code is bigger, the value of con-
trast become higher.
When a code cannot be read, the value is 0.
F
Focus
0 to 100
Indicates the focus of the image using the
change of density at cell edges.
When out of focus, the code cannot be read.
When the cell edges are sharper, the value of
Focus become higher.
When a code cannot be read, the value is 0.
P
Cell size
Depends on the size of the code.
Depends on the size of the code.
GDA0
Overall quality
0 to 4
Overall quality of 2D code based on ISO/IEC
TR29158(AIM-DPM-1-2006). The lowest grade
of the individual indices is the overall quality.
GDA1
Decode
0 to 4
Evaluates whether decode was successful.
GDA2
Cell contrast
0 to 4
Evaluates the difference between the average
of the white cell density and the average of the
black cell density.
GDA3
Cell modulation
0 to 4
Evaluates the deviation of cell brightness.
GDA4
Fixed pattern damage 0 to 4
Evaluates the degree of fixed pattern damage of
the code.
GDA5
Axial nonuniformity
0 to 4
Evaluates the degree of vertical and horizontal
distortion of the code.
GDA6
Grid nonuniformity
0 to 4
Evaluates the position deviation of each cell.
GDA7
Unused err. Corr.
0 to 4
Evaluates the proportion of unused error correc-
tion during decode.
