Option 3: Recognition Flag
Option 4: Corner detection filter:
2) Special 2: NS Base Search
In this mode, SOJ recognition is performed by first using the leads in the N/S
direction, then based on the data, the recognition of W/E direction is performed.
Option 1: Lead detection flag (same as Special 1)
Option 3
: Recognition Flag (same as Special 1)
3) Special 3: WE Base Search
In this mode, SOJ recognition is performed by first using the leads in the W/E
direction, then based on the data, the recognition of N/S direction is performed.
Option 1
: Lead detection flag (same as Special 1)
Option 3: Recognition Flag (same as Special 1)
4) Special 4: Check Direction
It compares the average brightness of the specified circular region and the
other circular region located 180 degrees opposed (diagonal) from the
specified circular region in order to identify the direction.
Option 1: Lead Detection Flag (same as Special 1)
Option 2: Direction of mark: (0:N, 1:S, 2:W, 3:E)
Option 3: Recognition flag (same as Special 1)
Option 4: Corner detection filter (same as Special1)
Bit position
Excessive Lead Check (0:Non, 1:Exist)
(It checks whether the extra leads exist outside of pitch 1)
Bit position
Lead Search Filter: (0:None, 1:Once, 2: Twice)
(Noise
elimination
filter is used when detecting the corner.)
Right Angle Fitting: 0:None, 1:Exist
(It checks the perpendicularity of the candidate
adjacent sides when extracting the corner.)

Set the direction determination data to the second Lead Group of the direction set in Option
2.
- Number of the leads
* “Angle correction” mode needs to be custom ordered.
- Lead pitch: Min. Brightness Difference (If the value is 0, 50 is set)
If the difference of the average brightness of the detected circle is less than
the value specified here, it is determined to be an error.
- Lead width: The diameter of the detecting circle (mm)
- Reflect LL: 0
- Find Pos X: The center position X of the detecting circle
- Find Pos Y: The center position Y of the detecting circle
