Partial Input with DAP (Dual Axis Partial) Processing

Would you like a little more positioning accuracy?

Do you need a wider ﬁeld of view?

We hear you, and that is why we have greatly im-

proved the resolution of our camera.

The 1.3 megapixels maintain precision and accuracy

while also enabling a wider ﬁeld of view.

Precision 1.3 Megapixel Camera

Sub-pixel Processing

Processing time can be further reduced by limiting

the camera input to only the area that is required

for inspection. Previous models allowed trimming

only in the Y direction, but now you can specify a

range across both the X and Y axes for trimming.

Keep a wide ﬁeld of view and trim to only the sec-

tions that are required for inspection in each scene

to reduce processing time.

Integrated Sensor

Previously, position information could only be

output on a per-pixel basis, but now you can output

at a resolution even higher than the number of avail-

able pixels. This provides ﬁner measurement values

for travel distances and helps to improve positioning

accuracy.

[ Problems with a Standard Digital Zoom ]

Camera input is performed for all images and only a portion is

shown enlarged, so this does not decrease the amount of time

required for camera input.

760,000 Pixels

Note: DAP processing is provided only on 760,000-pixel and

1,300,000-pixel Sensors.

Typical Problem

Sub-pixel Processing

The position of the edge

cannot be detected accurately.

The position of the edge is

detected with greater accuracy.

Partial input allows you to input only the portion of

an image that is required for inspection by changing

scenes, without having to change the ﬁeld of view.
