SECTION 1
Outline
 Dot code images can be converted to easy-to-read images.
Dilate or Erosion processing converts code images that have a small dot size and are difficult to
read into images that can be read reliably.
Refer to page 94 (Sec.5).
 A maximum of ten patterns can be registered for one scene.
If multiple patterns are registered, even codes subject to dispersion in the dot spacing or printing
quality can be read. It is also possible to read codes with different matrix sizes and symbol colors
in the same scene.
Refer to pages 105 (Sec.5) and 130 (Sec.5).
