How digital camcorders work
Consumers have been using camcorders since early 1980s. Since then they have gotten better and cheaper, with prices starting at only a few hundred dollars, making DV camcorders affordable for anyone. Shooting home videos is fun, everyone loves filming their families during special events. From your kids birthday, your son's soccer game, to the family trip to Mexico, but how exactly do video cameras work? Digital video cameras convert analog video into a digital format. Digital video camcorders take the analog information in the video camera and then translate it into bytes of data. Digital video is converted from moving images to a stream of zeroes and ones. The digital video camcorder records the bytes of digital information onto one of three items, a hard disk, a dv tape, or a DVD. From there you have the ability to transfer the video to your computer. You can then edit the video, email it to friends and family or even add the video to a website. The digital video process begins at the lens in the camcorder. The lens stores and then focuses light from the video that you are capturing onto the image sensor located behind it. Because the Charge- Coupled Devices (CCDs) used by camcorders are capable only of measuring the amplitude of the light hitting the photodiodes on their surfaces, a system of filters is required to establish just what color that light is. Another part of the camcorder, that plays an important role is the viewfinder. Originally view finders where black and white, as time progressed viewfinders have evolved into color LCD screens. This is a necessary part of the camcorder, it lets you see what you are filming. Newer models of viewfinders even let you add effects to your video via an LCD touch screen while you are filming.
