want to delete, or select "Delete" from the pop-up menu
displayed with the FUNC key.
To delete all the registered character patterns, select "Delete
All Label".
Be aware the deleted patterns cannot be restored.
2.
Select "Yes" following the displayed message.
The character pattern you selected is deleted.
Point of images to be used for dictionary
- Register a clear image as much as possible (imaged served as a model) in the dictionary.
An illegible character causes false recognition.
- A maximum of three character patterns can be registered for each label, but it is not necessary to
register all of them. One character pattern is enough.
If there is a lot of variation in three images or they are illegible, it may reduce the accuracy of the
dictionary.
In a case where "a noise tends to be generated at this point each time", also register an image "that is
with a noise in the background but the character is clear" to the character pattern besides an image
without a noise. It is important that characters are not illegible.
Example where the same character is
captured several times
In the right figure, characters
"IMAGECHECKERPV230" are captured.
There are three "E" and two "C".
If character assignment is performed on
all segmented characters in the
"Character Assignment" menu under
"Registration", three "E" and two "C"
are registered in the dictionary as
shown in the right figure.
If the size and the font of these characters
are the same, only one of them is enough to
be registered in the dictionary. In that case,
skip the characters not to be registered and
leave them as "_" as shown in the right
figure.
