In English, a camera is a device that captures and records visual images through the use of an optical system. Cameras come in various forms, including digital cameras, film cameras, and professional-grade cameras used in photography and cinematography.
A camera typically consists of a lens that focuses on the subject, a mechanism to control the amount of light entering the camera (such as an aperture), and a sensor or film that captures the image. The captured image can be stored digitally on a memory card or film, and then be viewed on a screen or printed out.
Cameras have evolved significantly over time, from early pinhole cameras to the sophisticated digital cameras we have today. They play a vital role in many fields, including art, journalism, surveillance, and entertainment.
