The difference between camera and dv

A camera refers to a device that can shoot programs, and DV refers to a handheld digital camera. But when it comes to cameras, it usually refers to "cameras for professional program shooting". And DV is a "home camera".

The differences between the two cameras mainly include:

1, different picture indicators

The programs shot by professional cameras are used for broadcasting, so the indicators are definitely high. DV is used for family records, so the requirements for indicators are not high.

2. Different parameter control.

Professional camera shooting needs precision, so the parameter control function is powerful. DV is used for video recording, so it has many automatic functions.

DV is the abbreviation of Digital Video, which means "digital video" when translated into Chinese. It is a digital video format jointly developed by many famous home appliance giants such as Sony, Panasonic, Shengli, Sharp, Toshiba and Canon. There are also English abbreviations such as spray valve and digital voltage source.

Classification by purpose:

1, broadcast type number:

These models are mainly used in the field of radio and television, with high image quality and good comprehensive performance, but with higher price, larger volume, highest definition, largest signal-to-noise ratio and best image quality. Of course, the price of several hundred thousand yuan is not acceptable to ordinary people. For example, Panasonic's DVCPRO model above 50m and so on.

2. Professional models:

These models are generally used in professional TV fields other than radio and television, such as audio-visual education, and the picture quality is lower than that of broadcast cameras. However, in recent years, some high-end professional cameras have surpassed the old models of broadcast cameras in many aspects, such as performance indicators, and the prices are generally between tens of thousands and hundreds of thousands of yuan.

Compared with consumer models, professional DV is not only cooler and more eye-catching, but also much higher in configuration, such as using lenses with better quality and performance and larger CCD, which is more prominent in imaging quality and adaptability to the environment.

For friends who pursue image quality, the surprise brought by the improvement of image quality cannot be measured by money at all. Representative models such as Sony's DVCAM series models.

3. Consumer model:

This kind of camera is mainly suitable for home use, and it is used in non-business occasions where image quality is not high, such as home entertainment. This kind of camera is small in size, light in weight, easy to carry, simple to operate and cheap. It can be used to make VCD and DVD for personal families in low-demand occasions, and the price is generally in the order of several thousand yuan to ten thousand yuan.

If we subdivide home digital cameras, they can be roughly divided into the following categories: entry-level DV, mid-range consumer-grade DV and high-end quasi-professional DV products.

Precautions:

1. Image quality is a very important technical index when purchasing. Refers to the resolution of the image taken by the camera, measured by horizontal resolution. The more lines, the clearer the image.

2. Zoom performance represents the flexibility of the camera and is another important indicator. By changing the focal length of the lens, the optical zoom effect is better. Of course, the bigger the multiple, the better. Usually, the magnification of optical zoom is between several times and 20 times. Some models of cameras can also increase the magnification of optical zoom through multipliers.

3. The number of functions is also an important indicator for choosing a camera. In addition to the necessary functions such as clock setting and various operation settings, there are also picture special effects, digital editing, faders, etc., which are almost necessary for all types of cameras.
