Features of the A230 Character Recognition Type
1.
Character recognition is possible using the neural net
(character recognition checker)
See p. 7 − 3.
− A maximum of five dictionaries (fonts) can be registered (comes standard with
two fonts: OCR−A and OCR−B).
− Compatible with connected letters and dotted letters.
− Cuts noise such as background patterns that can be mistakenly recognized as
characters.
− Recognized character strings are output serially.
− Compares the recognized character string with String Judgment (can be
changed by the external device.) to determine whether it matches or not.
2.
Allows easy character−by−character inspection
(Character Verification Checker).
See p. 8 − 3.
− Checks for missing characters, dirt, blurring, and incorrect
characters on a character−by−character basis.
− Just enclose the text with a marquee to extract and register each character as
a reference image for inspection.
− The Background Processing function eliminates unwanted noise (background
patterns etc.) that may otherwise be interpreted as characters.
