Selects the reduced light.
Reduced light is lighting for images excluded from images used for inspection. (Reduced lighting does
not have to be selected.) Use the following procedure to select the reduced light.
1. Press the [Reduced Light] button at the "Luminance" screen to open the light sampling type screen.
2. Select one image with good contrast other than the object to be inspected, and press the [OK]
button.

Set the threshold value.
1. Press the [Sampling] button.
2. Click the location to be detected in the upper left image. The clicked luminance is plotted with red
dots in the upper right image.
3. Select the "Sampling Type" - [Remove] radio button, and click the location that is not to be
detected. The clicked luminance is plotted with blue dots in the upper right image.
4. Press the [Sampling] button again to end sampling.
5. Press the [Detected] button to verify the area sampled and shown in red in the upper left image. The
luminance area shown in gray in the drawing upper right is sampled and shown in red. If the
threshold slide bar is moved or reduced light is selected, adjust by dragging the gray area and
changing the angle so that only the detection object is shown in red. If the gray area is changed
and the angle changed, the reduced light magnification is also changed.

TIP
Adjustment is also possible without performing sampling by adjusting the threshold slide bar or changing the angle of
the gray area. The reduced light magnification value can be changed by pressing the [Reduced Light] button and
entering the magnification directly.

Multiple threshold value settings
If there are differences in inspection object luminance due to differences in part lots, inspection can be performed by
setting four different threshold values for a single step.
1. Press the "LIGHT" tab at the [Data Edit] - "Step" screen.
2. Set "Thresh 2", "Thresh 3", and "Thresh 4" to "Use" only for the number of set threshold values.
3. Use the threshold value setting bar to display only the inspection object in the step screen in red.

Selects the sampling light.
1. Select "Color" for the sampling light type, and then press the [Light Detail] button.
2. Press the [Sampling Light] button at the color screen, select one image from the sampling light list
that shows the inspection object with good contrast, and press the [OK] button.

Set the threshold value.
1. Press the [Sampling] button.
2. Click the location to be detected in the upper left image. The location with same color as the
clicked location is shown in red. When a large area of the part being sampled turns red, press the
[Sampling] button again to end sampling.
3. Press the [Detected] button to verify the area sampled and shown in red in the upper left image.
4. Move the three threshold slide bars to adjust the threshold value until only the inspection object is
shown in red. The area shown in red with Green Ratio, Red Ratio, and Luminance images is shown in
red in the upper left of the image.
