Image Gain
The image gain affects the camera’s ability to decode the barcodes by modifying the
image exposure. Increased gain increases the brightness and clarity of an image at a
given exposure.

tic | Image Viewer. The Image Viewer

3. In the Imag
e Viewer, hold the mouse pointer over any white area of the target.
LPI/DPI Calibration
Lines Per Inch (LPI) and Dots Per Inch (DPI) values read by the AV7000 must be within
5% of each other. The goal is for the AV7000 to capture square pixels. This is especially
important with certain barcodes and in cases where Optical Character Recognition
(OCR) is required.

tic | Image Viewer. The Image Viewer
window opens.

ter dot to the outer edges of the outer circle as shown below. This image is obvi-
ously elongated, and corrections must be made.
