The first camcorder was invented by Jerome Lemelson in
1980. And since that time the first bulky analog video camcorders have evolved
into the modern digital camcorder, so small they can fit in the palm of
your hand, and so clear they rival even professional broadcast video cameras.
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.
Newer DV camcorders can not only shoot high definition video (up to 720 lines)
but models such as the Sony
hdr-fx1 hdv camcorder, Canon
xl2 and the Canon
zr200 mini dv camcorder even offer digital
still image capabilities. You can snap crystal clear images with resolutions
up to 1024 x 768, perfect for family photos. Need to email your videos to friends
and family across the globe, no problem. With the MPEG feature you can even
email short video clips to any one with an email address! Grandparents in Europe
can see your daughters birthday 4 minutes after you have filmed it in the U.S.A!
Even though current
digital
video camcorders come in a range of sizes and shapes, the techniques
used to convert moving pictures hasn't evolved much. But
the styles of digital camcorders have evolved. You can find digital video camcorders
come in all types, from dvd
camcorders to mini
dv camcorders. As technology changes video is not restrained to digital
video cameras. cell phones now have the capability to shoot video and
email the clips instantly anywhere in the world. It's hard to predict how
far video technology can go, the sky seems to be the limit.
