Camera connection and image capture
The 'Device' menu in the main toolbar provides a function to connect to a capture device.
Here is a simple example.
Click on the 'Connect' button to see the live view and then click on the 'Capture' button to grab the image.
The 'Device' menu allows a user to connect/select/disconnect the camera, set image format/resolution, and adjust the image bright/contrast/exposure.
To adjust image, click on the 'Video source' in the 'Device' menu (see below)
