The basic principle of the digital video camera is simply the light --- electricity --- the conversion of digital signals

Care must be taken during use to ensure the best performance of digital video cameras and take the best photos. In fact, the proper use of equipment is the best maintenance, because the correct use will not cause problems. Digital camera maintenance mainly has the following aspects:

(1) Add a hood to the digital video camera to avoid strong light, and stick a transparent protective film during use, which can more effectively protect the screen of the camera from being scratched.

High definition

As can be seen from the above figure, the attention of China's low-end digital video camera market has dropped significantly, mainly due to smart hands.

The failure phenomenon of digital cameras can be described as a variety of problems. According to the problems of different models, their solutions

Whether traveling or family gathering, digital video cameras are used very frequently. How to maintain and maintain the machine has become a matter of great concern to users. Regarding the precautions for maintenance, there are usually brief descriptions in the instruction manuals, but it is not enough for users who have comprehensive knowledge of maintenance. "Ten defenses" of the camera.

1.Anti-glare

Do not point the camera lens at the strong sun or other strong light source, because the strong light will burn out

1.CCD

The pixels of a CCD are an important indicator of the imaging quality of a digital video camera. The size of the pixels directly determines the sharpness, color, and smoothness of the captured image.

In addition to the manufacturing factors of the digital camera itself, the key is maintenance. In order to keep the camera in good working condition and prolong its service life, it must be carefully maintained, the framing device must be well maintained, and the use of power should be paid attention to: shockproof, antifreeze, heatproof, moistureproof, dustproof, etc.

Maintenance is one aspect, and it is important to pay attention to proper protection during use. Sometimes the wonderful moments make digital photographers excited, but the bad natural conditions have to make them amazed. At this time, as long as you know some effective protective measures, you can take pictures correctly. Let's talk about the maintenance and protection of digital cameras.

Digital Camera Cleaning

For digital cameras, the most time-consuming task is cleaning the viewfinder. Especially keep the lens and LCD screen clean. The first rule for cleaning the lens is to clean it only when it is needed. A little dust will not affect the image quality. When cleaning is needed, a soft brush, such as a mink brush or a hair dryer, should be used to remove dust. If you want to wipe the lens, you should blow the dust with an air pump before wiping it with lens paper, otherwise the dust may scratch the lens and the heartache will be too late; fingerprints will cause great damage to the lens, so it should be as fast as possible Remove it carefully and remember to close the lens cap when not in use to reduce the number of cleanings.

How to extend battery life, here are some ways to extend battery life:

Digital camera into the box without scratches

If you use Compact Flash, you don't need to worry about this problem. Because the interface of SmartMedia is exposed metal sheet, it is not difficult to scratch, and the card itself is too thin and easy to be broken. The safest is to put it in the box or camera.

Digital cameras change lenses faster

Point-and-shoot digital cameras are basically hermetically sealed. There is no need to avoid dust. High-end cameras with interchangeable lenses must always be on guard. When the lens is removed, as long as the CCD is dusted, all photos will be obliterated at any time. Therefore, when using this type of camera, the lens must be changed quickly.
