By calculating contour lines and judging,
stable positional detection is possible even
for hidden, overlapped objects that have
been difficult to detect up to now. Thanks to
this, better yields are achieved.
Gray scale matching makes sub-pixel
positional detection possible. Furthermore,
shape inspection, such as for the detection
of chipped objects, can be carried out
simultaneously with the gray scale
difference processing function.

Smart matching
Highly accurate and reliable inspection is
realized by automatically adjusting object
orientation and stop position deviation.
Since adjustment is done using gray scale
data, the AX40 shows its strength when it
comes to changes in brightness.
Complicated adjustments are possible
because of the priority adjustment function.
The AX40 uses a dedicated LCD VGA color
monitor. Visual clarity is in a league apart
from conventional NTSC monitors.
Judgment results are displayed large and in
color, which makes them easier to see. A
font consisting of 18-dot characters is used,
so even Japanese kana and kanji
characters can be displayed.
Versatile rotational and positional adjustment
The shape of the
inspection area can
be set to match
particular targets.
Also, mask area
settings can also be
combined so that
efficient inspection
can be carried out
just for a required
part.

Fine adjustment for
color inspection is
possible. Even
when colors
resemble each
other, the target
color alone can be
extracted to enable
highly accurate
inspection.

The computation function, which has been
troublesome up to now, now supports
Japanese, so settings can be easily made,
even by beginners to image processing.
Also, operation has become even easier
thanks to the ability to set both numerical
calculation and judgment output on the
same screen.

Versatile image processing that enables gray scale and color processing.
Verify images on a beautiful color monitor. View two images simultaneously.
In order to boost rotational position
accuracy, filter processing is used to
realize stable image processing even for
images containing much noise.

Differentiation processing is possible in addition to color and gray scale processing and binarization. High precision image processing
means you can use it in a wide range of applications.
