Mask Model Image (Image including component and electrode).
(1) Mask Area
Specify the area to mask in the model image.
1.
Click (Create Window) button in the Image Operation tool bar.
Drag and drop the cursor to form a rectangle in the model image.
2.
Click either of the buttons below to specify the area to mask in the
model image.
Automatically set the mask per
character and mark.
Mask the area inside the drawn
rectangle.
Enables the area inside the drawn
rectangle.
Mask the area outside the drawn
rectangle.
3.
Repeat the above procedure to specify multiple areas to mask.
To clear the masked areas, click .
(2) Extraction Area Ratio
Specify the ratio (%) of the pixels to binarize (for extraction) to the entire unmasked area
(100%). The pixels of the color specified in (3) are extracted starting from those with the
lower brightness or saturation, until the specified extraction ratio is reached.
The ratio can be specified in the range of 1 to 99.

(3) Binarization Color
Select the color used for binarization from the options: Red / Green / Blue / Saturation.
(4) Reverse Color
If this checkbox is selected, the pixels of the color specified in (3) are extracted starting from
those with the higher brightness and saturation until the ratio specified in (2) is reached.
(5) Add Model Button
Clicking the button creates a mask model based on the image.
(6) Component Difference/Polarity Difference Inspection Switch
Setting the toggle button ON/OFF specifies the mask model to use for which inspection.

(7) Model Set Selection Combo box
Select a model set to belong from the combo box. Specify non-defective items with the same
character/mark for one model set. The measured value closest to the non-defective item in
the set is used for non-defective/fault judgment. If more than one model set is being
specified, the value closest to the fault item between the sets is used for non-defective/fault
judgment.
Shown below is an example. Non-defective/fault item images shown below are
assumed.
