Quadrus EZ Reader User’s Manual 9-9

Camera Setup

Region of Interest by ESP

1. From the Camera menu, click the ROI

tab to bring up Region of Interest.

If you haven’t already captured an

image, click the Capture and Decode

button to decode the present image. If

successful, the Good Read indicator

on the ROI tab will be green and the

symbol will appear in the pane below.

Note: You can resize the image by

clicking and dragging the ESP window

from the lower right corner. This is useful

where very small symbols are being

read.

2. Click and drag your cursor over the

symbol that you want to isolate for

reading.

Notice that the surrounding area goes

black.

You can use the handles on the image

area that you have just drawn to resize

the region of interest. You can also

click on the center of the region of

interest and move it about.

3. Test the new settings in Read Rate

mode.

Note: to remove the region of interest, click

the Reset button or just click anywhere in

the ROI pane.

Note that all pixels not in the ROI are

defined as black.

Because the Quadrus EZ has much less

processing to do in a smaller window, read

rates typically increase dramatically. One

possible downside is that the chance of missing a symbol increases with the smaller window.

Always verify that your ROI will be large enough to allow for any random movement of

symbols in your FOV.
