Video and digital cameras use an electronic image sensor, usually a charge-coupled device (CCD) or a CMOS sensor to capture images which can be transferred or stored in a memory card or other storage inside the camera for later playback or processing. A wide range of film and plate formats have been used by cameras.

What is a video camera and how it works?
The electronic or VIDEO CAMERA is similar to any other camera in that light reflected from an image is focused by a lens onto a plane inside the camera. Unlike the film camera, the video camera contains a CAMERA TUBE which processes the image.
How do film video cameras work?

How a camera works step by step?
A camera lens takes all the light rays bouncing around and uses glass to redirect them to a single point, creating a sharp image. When all of those light rays meet back together on a digital camera sensor or a piece of film, they create a sharp image.
How does a video camera work physics?
Cameras use convex lens to take real inverted images. This is because light rays always travels in a straight line, until a light ray hits a medium.The glass causes the light rays to refract (or bend) this causes them to form inverted on the opposite side of the medium.

How does a camera focus?
To allow your image to be sharp, or to allow you to intentionally not focus, the camera and lens work together to change the distance of the lens from the sensor or film in order to control where the captured light converges. When the light converges precisely at the plane of the film or sensor, the image is in focus.
How do point and shoot cameras work?
A film or digital camera in which the focus and exposure is entirely automatic. The user aims the camera and presses the button; the camera does the rest. Point-and-shoot cameras can range from cheap throw-aways to pocket-sized digitals.

How long will a camcorder record?
The maximum continuous recording time for a movie is approximately 13 hours. The camcorder uses the VBR (Variable Bit Rate) format to automatically adjust image quality to suit the recording scene. This technology causes fluctuations in the recording time of the media.
