Picture Diagnose feature at Settings page is here to help you fine tune AmbiScreen settings according to your hardware display/player setup when navigating to Settings » Diagnose page (accessible via webapp and Lite settings webapp).
Two main features in Diagnose are available – live Screenshot preview and option for downloading Configuration file.
If you want to check what video image your device is processing for LED colors, click on “Screenshot preview” button. You can fine tune this screenshot, just fill in your custom values, then click on “Screenshot preview” button. You will see screenshot with your custom values.
Note: When you want to check screenshot with these settings, it is necessary to have your video source plugged in.
All values can be fine tuned, such as image width, height, frameDecimation, sizeDecimation, cropping and color signal thresholds.
