2.3.1  Image Filter 

Grayscale Preprocess   

Select a maximum of 10 types from the following 21 filters for a 
captured gray image. The combination is called a preprocess group, 
and a maximum of 16 preprocess groups (A to P) for 1 type and 1 
camera can be stored. 

This preprocess function is the data common to all checkers. 

 

1. 

Select one from preprocessing group A to P in "Grayscale Preprocess". 

2. 

Select “Filter Type” and specify the desired filter from 21 types. 

Selectable preprocessings are as follows. 
Dilation / Erosion / Erosion -> Dilation / Dilation -> Erosion / Auto Correct. / Gray Cut / Area Averaging 
/ Correction Setting / Median / Smoothing / Sobel / Prewitt / Laplacian / Edge Extract. X / Edge Extract. 
Y / Sharpen / Tophat / Dynamic / Frequency Extract. / Rotation / Reflect 

 

 

Refer to Chapter 4.6.5 in the PV200 User's Manual for the details of preprocess filters and setting procedure. 

Threshold method 

Select one from the following three threshold methods according to the status of images, and set required items. 
Adjust checking segmentation results, together with "Segment pre-process filter" mentioned in the next page. 

 

Threshold 
method 

Usage 

Fixed 

When the brightness of image is always constant, and the brightness over the 
image is even. 

Auto 

When the brightness of whole image varies every time the inspection is executed 
although unevenness of brightness is less. 

Dynamic 

When the brightness of the image in the inspection area is uneven. 

Fixed 

A method to binarize based on any specified value. 

Use it when there is no uneveness of brightness in the inspection area and the brightness of whole image does 
not vary every time the inspection is executed. 

1. 

Select “Fixed" in "Threshold method". 

2. 

Set the color of characters in "Segment Color". 

If the characters are brighter than the background, select “White”. If the object image is darker than the 
background, select “Black”. 

3. 

Select from slice level A to P in "Slice Level".
