Drawing an Area: In the case of Area Shape = Line
1.
Set a start point (ST) and an end point (ED).
You can set an area in the vertical and oblique
directions as well as in the horizontal direction.
2.
Set the size of a cell (W) which is a rectangle
calculating the average brightness.
The widths in X and Y directions of a cell are
defined as the figures shown right.
3.
Set the number of cells (N).
Settable number of cells: 3 - 256
Set the number of cells in order to inspect the
object thoroughly from the start point to the end
point 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 and
cell size. Specify the number of cells in order to
inspect thoroughly even if an area size will become
larger.
The Number of Cells (N)
The lower figure is an example of occurrence of area
that cannot be inspected due to lack of cells.
