3-5 Adjusting the Images That Were Taken
Image Adjustment
You can adjust the image that is taken by the Sensor to make it easy to measure.
There are mainly the following two types of items that you can use to adjust the image.
• Filtering the Images (Filter Items)
These items filter the image by eliminating image noise with filters to make them suitable for measurement.
• Compensating for Position Offset (Position Compensation Items)
These items compensate for offset in the position or orientation of the image.
You can combine several filter items and position compensation items to adjust the image that was taken. (You
can use a total of up to eight filter and position compensation items combined.)
Flow of Image Adjustment
The image that is taken by the Camera (called the Camera image) is adjusted in the order that the filter and
position compensation items are registered.
You can specify the order of image adjustment by registering the items in the desired order, but you cannot change
the order of the items after you register them.
