OCR/OCV scanning settings
Settings of the adjusting window:
Adjusting over X(horizontally) and
from the left and over Y (vertically)
from the top.
Ramp form light to dark.
If a mask is selected a mask generator
will assign a function to every
character. If variable length is
selected all characters found in the
scanning window will be scanned.
The output string can be made up
with zeros up to a fixed length, if
required.
The characters are dark on light
background.
The compliance proportion should be
at least 90 %.
The minimum height of the
characters should be at least 20 pixels
and the minimum width 6 pixels.
If inside a character distances of up to
5 pixels are present it will be scanned
as one character.
The minimum distance between the characters should be at least 1 pixel.
The division factor is defined by the proportion height to width * 10.
The grey scale value threshold indicates the minimum contrast that may be present.
The control function is used to insert information in the scanned characters. CNTR and the
mouse are used to add individual control outputs.
In order to edit additional menu items the character string to be scanned should be read and
the display in the window should be set to at least 320 x 240. If separating is selected the
following interface will be displayed. The buttons display (adjusting window or scanning
window) will display the selected window.
In the figure below the adjusting window is shown in green.
Use the mouse to reset or move the window. This is also possible by directly entering the
coordinates.
