“000” is added in case of No Read.
5.2.3 Symbol Type Information
Add symbol type information (decoded symbol type) to the head of decoded symbol
and output is in serial. Symbol Type is not added at No Read.
5.2.4 Decoding Time
Add decoding time to the symbol data.
5.2.5 Total Reading Time Information
Add number of images captured after trigger input and Total time from trigger
input to serial data output. Total Reading Time is not added at No Read.
Output format: (aa, bbbbbms)
aa: Number of images,
bbbbb: Total time [ms]
5.2.6 Contrast Information
Add the Contrast Information of the last decoded image.
Good Read
Calculate contrast value of a symbol including quiet zone. The decoder
determines a rectangular area for the symbol and calculates the contrast value
from its brightness level.
If there are multiple symbols, the calculated value is for the first decoded
symbol.
No Read
Calculate contrast value for the whole image.
Output format: (aaa, bbb, ccc)
13 bytes
aaa : Maximum value of reflectance
(000 to 255)
bbb : Minimum value of reflectance
(000 to 255)
ccc : Contrast [%] =100 x (aaa - bbb) / 255
(000 to 100)
