Switching Images Changes the Viewing Position
The ScanSpection system uses multiple Images to accomplish the inspection
process. The Images are located at a fixed offset from each other. To simplify
the user interface and to reduce the confusion to the user when the system
switches Images, the system automatically repositions the Image every time
there is an Image change. This ensures that the video cross hair stays with
the same position on the board before and after an Image change.
To the user, an Image change should only appear as a magnification change.
The system automatically compensates for the offset distance between the
Images.
If it is observed that the system does not compensate the offset correctly, the
Image offset needs to be re-calibrated. The instructions on how to calibrate
Image offset are given in the previous section.
