In the case of Area Shape = "Plane"
1
. Set a start point and an end point.
Set a start point (STX, STY) and an end point
(EDX, EDY). PV scans from the start point to
the end point.
If the scan direction is set to
"Horizontal/Vertical", PV scans in both
directions.
2
. Set the size of a cell which is a rectangle
calculating the average brightness.
3
. Set the number of cells.
Settable number of cells:
- Number of cells X = 3 - 256
- Number of cells Y = 3 - 256
Set the number of cells in order to inspect the
object thoroughly from the start point to the end
point in both directions of X and Y, and not to
overlap cells each other as the figure shown on
the right. If the cells overlap each other, the
checker repeatedly scans the parts where the
cells are overlapping, resulting in increasing
inspection time.
Changed area size by Area Size Adjustment
function does not change the number of cells.
Specify the number of cells in order to inspect
thoroughly even if an area size will become
larger.
Scan direction: Horizontal
The lower figure is an example of occurrence of area
that cannot be inspected due to lack of cells.
