A digital video camera (DVCAM) is a device that captures motion picture information from live environments, encoding it into data that can be decoded or transcoded into electronic visual media. A typical digital camera consists of a lens, image sensor, storage media and a number of other features that can also be found on other cameras (such as scalable aperture, filters and flash).
Video technology dates back to the mid-twentieth century, with the first video tape recorders used for television broadcasts in the early 1950s. Around the same time, digital technology was evolving in the realm of computer programming. However, video remained an analog format for the next few decades.
The primary difference between analog and digital media is that, while the former is a continuous stream, the latter consists of discrete values (digits) that represent picture information. Analog video cameras were at first very large and difficult to operate, but by the 1980s evolved into portable "camcorders." Eventually, camera devices adopted the ability to record digital information, and as its quality surpassed that of previous analog formats, digital video has largely replaced most other moving image formats. Now most video cameras available on the consumer market are digital video cameras. The digital format allows for easy editing and sharing of video.
