Evaluation
Evaluation
In Evaluation , you can view images
currently in the Verifier, capture and
decode a symbol, save it as a digital file,
and perform histogram and line scan
evaluations.
When you click on the Evaluation tab,
you will see the images that are currently
stored in the Verifier.
Click Receive to refresh this view.
Click Capture/Decode to display the
current stored image. Only one capture/
decode event will occur, regardless of
read cycle settings.
Click Read to trigger a read cycle. If
there is enough time in the read cycle, up
to 32 good reads (or 6 full-scale images)
can be captured and displayed, depending
on the size of the images, and depending
on the number enabled in
Number of
Captures under Capture Mode in the
Camera Setup menu tree to the left of
the tabs.
If you click Save , the current image will
be saved to the location of your choice.
Note: An image can only be saved in
the format in which it was uploaded to
ESP . JPEG images will be saved as
.jpg , and bitmaps will be saved as .bmp .
When you click the JPEG Image box,
notice that the Line Scan button is grayed out.
The JPEG option allows faster captures and transfers, but since the JPEG standard compresses
image data, it is not suitable for the more rigorous demands of line scan evaluation.
JPEG also allows you to adjust the image quality (resolution) by adjusting the sliding tab
between 1 and 100, 1 being the lowest quality and 100 being the highest.
When possible, use the highest quality; when image transfer speed must be increased,
use a lower image quality setting. Adjustments for this setting will depend on your specific
hardware and software limitations.
