What is the difference between image formed in a projector and camera?

The main difference between the images formed in a projector and a camera lies in their purpose and orientation. A projector creates an enlarged, inverted image by shining light through a transparent slide or digital content onto a surface, allowing the audience to view it. In contrast, a camera captures images by focusing light through a lens onto a sensor or film, producing a smaller, upright image for storage or display. Essentially, a projector is designed for display, while a camera is meant for capturing and preserving images.
