Auto Focus Multi Code Reader V430-series User’s Manual (Z392) 10-5
Camera and IP Setup
Evaluation
In Evaluation, you can view images
currently in the reader, 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 reader.
Click Receive to refresh this view.
Click Capture/Decode to display the
current stored image. Only one capture
and 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.
