The target object is binarized, then the component is detected from the detected target object.
This mode can be used for recognition of the irregular shaped components.
It is possible to use the fixed threshold and the automatic threshold for binarization.
White objects are normally recognized, but it is also possible to detect black objects on
a white background.

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.

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.)
Note
*2
: The size (surface area) of the object being detected is set to the “Reflect LL.” and
“Lead Width.” field. The surface area of the lead is obtained from the following
formula:
The lead length x the lead width.
Note
*3
: The inner center position in the Y direction of the detected object lead is set at the
position offset from the component center.
