Analog Formats Are Out, Digital Video Cameras Are In
Most people today wonder why digital video cameras are superior to the cameras of yesteryears. The reasons are many. To begin with, the technology that drives digital video cameras is totally different from the one that has been used hitherto. All photographs that are taken with digital video cameras consist of millions of minute dots of light arranged in a grid. Every single such dot is called a pixel. You might wonder why a person says that a picture is heavily pixilated. It only proves the fact that the resolution that a picture should be at, is not what it is supposed to be. If the number of pixels is higher then the images that they produce will be a lot clearer. It will also ensure that the colors that you have used are very realistic. However, while choosing a camera, it would be wise if you could ascertain the number of effective pixels a camera can capture; instead of the gross number of pixels. The term effective pixels, refers to the number of CCD or CMOS chips or sensors that actually process the recording of an image.
While going through the working of digital video cameras one can understand that the pixel information is captured on CCD or CMOS sensors, which are positioned just at the back the lens. How could one relate this particular feature to an analog camera that was used a decade or so ago? The answer is quite simple. The CCD or CMOS sensor does the same work that a film did in an analog camera.
Just as there can be variations in the kinds and sizes of films that exist for analog cameras, there can be various kinds of sizes of sensors that are used in digital video cameras. If the sensor is fairly large, it can easily capture more light, since it can sense a greater quantum of light that is coming in. When this happens, the quality of the picture is also enhanced; you are then able to get a picture which is not just clearer, but is also a pleasure to look at. The colors presented in the photograph are incredibly rich and full of life. For instance if there are pictures that are taken with digital video cameras, you can be sure that every single details will be visible and clear. The colors are lifelike and there are no hues that do not reflect the actual image.
Another reason why the picture that is produced by digital video cameras is so vivid is that there is usually more than one sensor in the camera. Single sensors cannot produce pictures that are as clear as those produced with three or more sensors. In the technology that is available now, three sensors capture the three primary colors such as red, green and blue which are used in various combinations to produce the right tone and color.
