Two-edge Midpoint Compensation
This position compensation item detects edges in two directions.
If the specified color is detected (or the specified density is detected for a Sensor with a Monochrome Camera),
it is recognized as an edge. Two edge positions are detected.
The image is adjusted so that the coordinates of the midpoint position of a line that connects the two detected
edge positions matches the position when the edges were registered.
