In the description of the VHSC Camcorder that I used for my assignment it states that the Camcorder has 270,000 CCD resolution maximum. In the description of CCDs in the reading they talk about having one, two or three CCDs in digital camcorders. Zooms are constructed to allow a continuously variable focal length, without disturbing focus. To achieve this, the optical zoom uses a combination of lenses that magnify the image prior to being registered at high resolution by the sensor . While the digital zoom only changes the presentation of existing data, the optical zoom actually augments the data collected by the sensor.
Optical zooms are superior to digital zooms.
TTL viewfinders show the photographer precisely what the lens sees, avoiding parallax problems. My school has a Canon Elura Digital Video Camcorder. The school has ordered this but they have not received it. Industry analysts predict a surge in IEEE 1394 product shipments and expect the market to grow from less than 2 million devices in 1997 to more than 460 million by 2011. Products supporting the 1394 standard go under different names, depending on the company.
