4-18 QX Hawk Industrial Imager User Manual
Evaluation
Evaluation
In Evaluation, you can view images
currently in the imager, 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 imager.
Click Receive to refresh this view.
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.
