Characteristics of digital video camera

The high-definition analog camera records analog signals, so the image clarity (also called resolution, resolution or resolution) is not high. For example, the horizontal resolution of VHS camera is mainly 240 lines. It is better to mention that the Hi8 model has only 400 lines. DV records digital signals, and the horizontal resolution has reached 500~540 lines, which is comparable to professional cameras.

The bandwidth of chroma and brightness signals of DV is almost six times that of analog cameras, and the bandwidth of chroma and brightness is one of the most important factors to determine the image quality, so the color of images taken by DV is more pure and gorgeous, reaching the level of professional cameras.

Lossless reproduction of the signals recorded on DV tapes can be transcribed countless times, and the picture quality will not be degraded at all, which is beyond the reach of analog cameras.

Small in size and light in weight, compared with analog cameras, DV cameras are greatly reduced in size, generally only about 123mm×87mm×66mm, and their weight is also greatly reduced, generally only about 500g, which greatly facilitates users, with a volume of only 74.7mm×6 1.9mm×26.9mm and a weight of only 90g..
