Moving image capture

Moving image capture refers to data captured by means of digital video cameras, webcams and TV cards. The essential parameters of any moving image sequence as a visual presentation are: presence or absence of colour, aspect ratio, resolution and image change rate.

The capture process fixes the ‘natural’ frame rate of the image sequence. This capture rate (i.e. the speed of the motion in real life) should be the same as the presentation rate (i.e. the speed at which the moving images will be shown as video), unless, for example, the video will be shown in slow motion.

All modern moving image capture systems use some sort of a mechanical and/or electronic shutter. In a camera, a shutter is a device that allows light to pass for a determined period of time, for the purpose of exposing photographic film or a light-sensitive electronic sensor to light to capture a permanent image of a scene. A shutter can also be used to allow pulses of light to pass outwards, as in a movie projector or signal lamp.

Once moving images have been captured in a digital form, the video can then be edited as part of the post-production process, and transmitted in different formats, e.g. by streaming over the Internet, or on a DVD.
