Setting up filtering and achieving a good image can be a challenging task and often can require a lot of repetitive testing and tweaking of parameters to get right. The VHV5 has an inbuilt feature that solves this via automatic optimisation of the imaging area per code.

If you select the region you have setup for your code, you will see two icons appear in the top right, one of these being the “Optimize” option.

Clicking on this will bring up the optimisation window for that barcode region only. Here you select “Optimize” and then you will need to acquire three images to proceed. In this example the camera is triggered through the button seen below (2), once you have three images the process will begin.

This process will take a minute or so (time will vary depending on complexity of image) to iterate through filtering options to determine what settings achieve the best reading based on the score, pixels per element, and time taken to process. 

From here you click “APPLY” and the settings are generated (remember to click save!) and then this can be carried out for each of the other barcode regions you have set.
