Setting Detect Mode
1.
Select “Virtual Circle Detect Condition” > "Detect Mode".
2.
Select a desired Detect Mode from the list.
Depending on the selected Detect Mode, detected data items to be displayed at the bottom of the screen
vary.

a) Virtual circle
Virtual circle is a true circle(*) that is calculated with the
coordinate values of the edges of an object detected by each cell.
Two detection methods are available. "General Mode" which
uses the coordinate values of all detected edges and "Details
Mode" which does not use the coordinate values of convex or
concave of an object for calculating the virtual circle.
*) When Calibration is employed, virtual circle (true circle) is
detected with the values after calibration. When Factor X and
Factor Y are different, it is displayed as an ellipse according to
the ratio. (Because the image displayed on the screen is the state
before calibration.)
