• Measurement Data That Can Be Used for External Outputs and Calculations
The following values can be used as measurement data and output to external devices via Ethernet or used in
calculations.
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 Shape Search Position
Compensation item, but it performs processing to detect differences in colors and patterns in addition to
processing for image pattern shapes.

Parameter Setting Description
Interpolation Bilinear (default) Points are connected with lines to find approximations. This create smoother
images.
None Position compensation is performed at the pixel level.
