Items to be set Set value
Explanation
Comp. Threshold
Sets the binarization level.
(If 0, the binarization level is set
automatically.)
Comp. Tolerance Specifies the tolerance as a percentage.
Search Area (mm) Sets the range of the detection.
Body Size X (mm) Sets the size of the outer edge.
Body Size Y (mm) Sets the size of the outer edge.
Body Size Z (mm) Sets the size of the outer edge.
Cntr. Offset X (mm)
Sets the offset amount in the X direction
from the center position.
Cntr. Offset Y (mm)
Sets the offset amount in the Y direction
from the center position.
Cntr. Offset R (mm)
Sets the offset amount of the angle of
rotation.
Ruler Width 0
Algorithm Special 2/3
Selects the recognition algorithm when
using a special algorithm.
Base Alignment Flip chip
Selects the basic component type when
using a special algorithm.
Vision Option 1 0
An index of the ball position definition
file.
Vision Option 2 0
Ball matching level (%)
(This is effective only for Special 3
algorithm.)
Vision Option 3 0
Vision Option 4
*Note 1
Specifies the noise cut for inside and
outside of the component, the order of
execution and the object type.
(This is effective only for Special 2
algorithm.)

Note *1: . This option parameter consists of one byte of data, and each bit has different
meaning (Please refer to “2.12.3-3. Mark 2, Note *3” for the details.)
As shown in Figure 79, the definitions for the individual ball positions are stored in a ball
position definition file (text file) (Lines beginning with // are comments.)

detection. Consequently, they should be defined as close to the outer edge as possible
within the various quadrants. (The user do not need to concern about making these positions
precisely.) It is possible to perform recognition by using Pos1 ~ 4, or Pos5 ~ 8.
