A camera is a device passed down to capture images, either as still photographs or Camera Cases as sequences of moving images (movies or videos). The indication comes from the camera obscura (Latin for "dark chamber"), an early bird mechanism of projecting images where an entire license functioned as a real-time imaging system; the modish camera evolved from the camera obscura.

Rangefinder cameras allow the extent to objects to be measured by means of a coupled parallax section on culminating of the camera, allowing the focus to be bent with accuracy. Single-lens reflex cameras allow the photographer to determine the focus and composition visually using the objective lens and a moving mirror to matter the image onto a ground glass or plastic micro-prism screen.
