2. All functions

2.1 Recognition method (based on light sampling type)

There are four methods available for recognizing inspection objects in order to perform inspection. Those

methods are luminance, color, shape, and X-ray. Select the image to be used for inspection, and then set the

threshold value to show the object to be inspected in red.

2.1.1 Luminance

Samples detection objects in region of specified luminance, and uses them as the object of inspection. Open

the "LIGHT" tab and select "Luminance" for the "Light Sampling Type".

Selects the sampling light.

Sampling light is the lighting used for inspection. Use the following procedure to select the sampling

light.

1. Press the [Light Detail] button to open the "Luminance" screen.

2. Press the [Sampling Light] button to open a sampling light type screen, and select up to two images

that show the inspection object with good contrast. The name of the selected images and

composite image of the selected images appears in the lower right. This image is used for inspection.

3. Press the [OK] button to save the settings.

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.
