    <h2>Reference Image and Camera Settings</h2>
    <details id="desc_details" style="font-size:16px">
        <summary><b>CLICK HERE</b> for usage description. More infos in documentation: 
                <a href=https://jomjol.github.io/AI-on-the-edge-device-docs/Reference-Image/ target=_blank>Reference Image</a>
        </summary>
        <p>
            The reference image is the base image on which the alignment markers, digit ROIs and anlog ROIs will be defined.
        </p>        
        <p>
            Initially the currently saved reference image is shown. If you start with a setup from scratch, a default image is shown as a placeholder.
            Use the button <b>"Create New Reference / Change Camera Settings"</b> to start the creation of your own reference image. After clicking the button, the camera will take a
            photo using the configured parameters. This will be your new reference image. With the button <b>"Update Reference Image"</b> you can update the image again.
        </p>        
        <p>
            To have a reliable evaluation processing, it is mandatory to have the digit ROIs horizontally aligned. Using the two input fields "Rotation angle" and
            "(Fine-tune)" the image can be rotated in both directions. The resulting rotation angle is used to pre-rotate the image before
            the alignment algorithm is processed to compensate only small misalignments (See next step Alignment Markers). Further information can be found in documenation:
            <a href=https://jomjol.github.io/AI-on-the-edge-device-docs/Reference-Image/ target=_blank>Reference Image</a>
        </p>
        <p>
            After setting up your reference image don't forget to save with the <b>"Save new Reference Image and Camera Settings"</b> button!<br><br>
            <b>NOTE:</b> There is no need to perform a reboot after every saving or step. It's sufficient to reboot after all configuration steps 
            (reference image, alignment, ROI configuration) are completed to activate new configuration.
