2. Connect the document camera to the computer: Use a USB cable to connect the document camera to the computer. Ensure that both the camera and the computer are turned on.
3. Position the document: Place the document or object that you want to display under the document camera. Make sure it is centered and clearly visible.
4. Adjust the document camera settings: Use the controls on the document camera to adjust settings such as focus, zoom, and brightness to ensure optimal image quality.
5. Open the document camera software: Launch the document camera software on the computer. This software may come with the document camera or be available for download from the manufacturer's website.
6. Display the image: In the document camera software, select the option to display the image from the document camera. This may involve clicking a button or selecting a specific input source.
7. Project the image: Connect the computer to a projector or display device using the appropriate cables. Set up the projector to display the output from the computer.

9. Control the image: Use the document camera software to control the image being displayed. This may include zooming in or out, highlighting specific areas, or capturing still images.
