Tune too, there must be skills to keep the camera in the best working condition (1)

Using the camera for video interaction, it is already very common. As the "eye" of video interactive communication, the performance of the camera will be directly Affect the effects of interactive communication. In order to effectively improve the video interaction, we must find ways to master some of the skills of the camera, so that it is often used. No, some of the usage tips summarized in this article will help you use the camera more efficiently!

Stay away from glare.

Considering that the camera contains plastic and polyester rubber components. These components are easily exposed to aging under direct sunlight, which greatly reduces the imaging effect. Therefore, when you place the camera, do not aim the lens directly at the strong sunlight for a long time. Also, keep the camera away from the heat source, because the camera will also occur when working in a high temperature environment for a long time. Aging phenomenon, reducing imaging results. Another point to remind you is that if the ambient light of the camera is too strong or too weak, the imaging effect of the camera is often difficult to achieve the most satisfactory state; for example, if the ambient light is very dim, then the camera image looks like Very dim, the picture may even look dark; of course, if the ambient light is too strong, then the camera image will look white. Therefore, choose a working environment with appropriate light brightness for video interaction, and the camera can not meet the light source to ensure a good effect.

Keep away from dust

Considering that the camera is exposed to the air directly during work, there is always some dust in the air, and the dust is likely to be scattered. On the surface of the camera, if the surface of the camera is not cleaned for a long time, the image of the camera will look blurry. Therefore, in order to avoid the camera from being invaded by dust, you must ensure that the camera works in a dust-free environment, and after completing the video interactive communication task, be sure to protect the camera with a cover in time to minimize the direct invasion of dust. opportunity. If you find that the camera image is blurry, check if the surface is covered with dust. If you find dust, you must first wipe the dust covering the surface of the camera with a soft cotton cloth, then use glasses cloth or professional lens paper. Wipe it again, and when you wipe it, try to start from the center of the camera. In addition, you need to remind everyone that if the lens focal length of the camera is improperly adjusted, it may affect its imaging image effect. Therefore, after the dust is wiped, the camera still cannot produce a good imaging effect, so be sure to pay attention to the lens focal length. the size of.

Direct touch is strictly prohibited

In order to improve the imaging effect of the camera, manufacturers often apply a special optical film on the surface to efficiently receive ambient light, but this kind of optics Once the protective layer is touched by the hand, it will leave a slight handprint or smudge on the surface, and this handprint or smudge will directly affect the camera's efficient absorption of ambient light, thereby reducing its imaging effect. To this end, no matter how clean your hands are, you can't directly touch the surface of the camera. Otherwise, it will not only damage its optical protective layer, but also cause the video interactive communication effect to drop.

Keep away from imaging breaks

Maybe when you use the camera for video interactive communication, you often encounter camera image breakage, which reduces the dynamic communication effect, so there is no way to avoid phase formation. The picture appears to be broken. Because the camera will automatically compress and transmit the imaging signal to the computer system through the data cable of the USB interface after imaging, if the computer's own hardware configuration is low, the system may not be able to respond in time. The video content so that the image displayed on the screen is naturally prone to breakage. In order to avoid or alleviate this imaging fracture phenomenon, we need to do the following:

First of all, we must ensure that the camera of the USB interface is installed in a computer system with high hardware configuration, otherwise the video captured by the camera will be dynamic. The content will make the USB cable overwhelmed; secondly, in order to improve the timely response capability of the computer system and the processing capacity of large-capacity data information, the CPU working frequency of the computer must be as high as possible, otherwise the system will not be able to compress in time. The video dynamic content has been quickly decompressed and displayed.

In the case that you can't upgrade or improve the computer configuration, you may want to eliminate the breakage of the image as much as possible by reducing the resolution of the camera display. In addition, in the case of conditional permission

, the working mode of the hard disk can be set to "DMA storage mode", so as to increase the ability of the computer hard disk to receive large-capacity dynamic video data as much as possible; In the working mode, you should first click the "Start" /"Settings" /"Control Panel" command, in the pop-up system control panel window, double-click the system icon to open the system's property settings window, click on the window " "Hardware" tab, then click the "Device Manager" button in the corresponding tab page to open the system's device list interface; expand the "IDE ATA/ATAPI Controller" option in the interface, and then right click on the following The "Main IDE Channel" sub-option, and execute the "Properties" command from the pop-up context menu to open the property setting interface of the main IDE channel. Click the "Advanced Settings" tab in the interface, open the settings window shown in Figure 1, then click the drop-down button in the "Transfer Mode" setting item of the window, and then select the "DMA" option from the drop-down list. Finally, click the "OK" button to complete the setting operation; in the same way, set the transmission mode of the secondary IDE channel to "DMA".

Keep away from the phenomenon of flower screen

When performing video interactive communication, you may also encounter the phenomenon of blooming on the image. How can we quickly eliminate it when encountering this phenomenon? In fact, the appearance of the screen on the image is generally not easy to occur. Once this phenomenon occurs, we can start from the driver side. First check if the camera driver installed in the computer system is consistent with the model of the camera currently in use. If it does not match or is inconsistent, you must uninstall the driver that was originally installed, and then install the driver that is equipped with the camera. Secondly, check if the computer system has several different versions of the camera driver installed at the same time, or see if several camera drivers developed by different manufacturers are installed at the same time. If there are multiple drivers installed in the system, you must first All drivers are uninstalled clean, and the original driver is installed in the correct way. The third one may wish to replace a display card, because some camera drivers may conflict or be incompatible with the graphics card and its driver, which may affect the display of the camera image, if it is replaced After a video card, the camera work back to normal, it means that the quality of the camera we are currently buying is not very good, you can consider the dealer to replace the new camera.
