• Using Filter Items for Processing with Position Compensation Items
To more effectively perform position compensation, filter items can be used to create an image specifically for
position compensation and then apply only the results of processing the position compensation to the image
that will be measured. The processing order of filter and position compensation items and the settings of the
source images are set up as shown below.

Shape Search Position Compensation
With this position compensation item, an image pattern is registered in advance. When the registered image
pattern is detected, the image is adjusted so that the image pattern is in the same position as when it was
registered.
This position compensation item performs the same type of processing as the Search Position Compensation
item, but it performs special processing for the shape of the image pattern.
Use this position compensation item to correct the position of a rotated image pattern.
