Digital Camcorder

A camcorder records a scene as a sequence of 25 to 30 still images per second, along with sound. It comprises a video camera to capture light from the scene, a viewfinder through which the scene may be viewed, a charge coupled device (CCD) to convert the visual data into an electric signal, and a means of storing the signal. Digital video cameras convert the signal into digital form - a series
of separate measurements  of the initial analogue (continuously varying) signal. They record the digital signal, usually on a chip or hard disk. Camcorders often have a slot where a memory card can be inserted to expand the memory and store longer recordings or more still pictures. Today there are many camcorders available like excellent quality camcorders for high budget money and low quality camcorders for less price.
