What does a document camera primarily provide?

A document camera primarily provides real-time image capture for displaying an object to a large audience. This technology is designed to enhance presentations by allowing the presenter to show documents, images, or physical objects live on a screen, making it easier for an audience to engage and understand the content being discussed.

The functionality of a document camera is particularly beneficial in educational and professional settings, as it allows instructors and presenters to showcase materials without needing to print multiple copies or rely on overhead projectors. The ability to zoom in on details and capture high-quality images adds to its effectiveness as a teaching tool or presentation device.

While other options mention useful features like static image storage, video conferencing, and audio recording, these do not reflect the primary function of a document camera. The main emphasis of this technology is its capability to provide a live display, making option A the most accurate choice.
