Acquisition lighting settings

This page gives you the possibility to configure backlight and frontlight acquisition settings:

• by providing maximum and minimum exposure time in milliseconds

• by providing exposure time increment (interval) in milliseconds

• by indicating which lighting is installed on the system

This settings will define the available acquisition settings that you can choose when editing a recipe.

Note

Exposure time is the time during which the camera is exposed to light when acquiring images. The longer the exposure time, the brighter the image is. You must choose an exposure time range that ensures good part detection.

Astuce

First, try using the default settings. If the images are too dark, return to this page and increase the minimum and maximum exposure times. If the images are too bright, decrease the minimum and maximum exposure times.

For example, configuration from Fig. 125 enables following image acquisition settings:

• Backlight: 1, 2, 3, 4, …, 20ms

• Frontlight: None because lighting is disabled

Note

If your system does not have a backlight or a frontlight, disable it with the switch on top right.

Avertissement

Changing these settings will affect all your recipes when re-starting image acquisition. It will not modify the settings already saved if they are unchanged.
