Camcorder is a device that combines both a video camera and a video recorder in a single unit. As compared to its previous technology that used separate devices for recording audio and video, a camcorder has a built-in recorder unit for recording both audio and video.
From the early generation of camcorder that used digital tape to store data to the more advanced ones that use non-removable media like hard disk drives to store, the camcorder has come a long way in the direction of technology and performance. The latest and sophisticated camcorders use two different storage media such as built-in HDD and memory card.
Major components:
Lens, imager and recorder are the three major components of the camcorders. Lens encompasses aperture, zoom and shutter. In a professional camcorder the lens is manually controlled for all optical functions. However, in a consumer unit it is generally controlled by the electronics of the camcorder. The prime function of lens is to gather and focus light on the imager. When the image is projected on the imager through the camera lens the light is converted to an electronic video signal. And last but not the least, it is the function of the recorder to write the video-signals to the recording medium. However, the record controlling system of the camcorders allows the user to control the device.
