Camera

Definition

A camera is an optical device that captures images, either as still photographs or as moving images such as videos. It works by allowing light to enter through a lens and projecting it onto a sensor or film, creating a visual representation of the scene in front of it. Cameras are crucial for visual perception in robotics, enabling machines to analyze their surroundings and make decisions based on that information.
