Under normal circumstances, as long as the camera is not physically damaged, its life is very long, and in some cases the camera failure caused by system or software reasons, the following small series for everyone to analyze the general Camera failure and handling methods. 1. Camera failure can not be found: A computer can not detect the camera of the newly installed USB interface. Analysis and processing: first check the operating system, then check the BIOS, USB interface and installation for errors. If the system you are running is Win 95 and it does not support the USB interface, you must update it to Win 98. The USB device must be enabled in the BIOS SETUP. If these methods do not work, try connecting the USB camera to the second USB port. Of course, it is also possible to install the wrong driver or select the wrong device, view the system device and install the driver again. 2. The speed of the camera is slow. Symptom: After installing the camera that I just bought back, I feel that the display speed is too slow. I changed the dial-up location and ISP, and the result is still very slow. Test this camera when you are not online, and find that the image is also very slow. Analysis and processing: This phenomenon is caused by the low performance of the computer. You can change the graphics accelerator card. If you still can't, you have to upgrade the CPU and motherboard, or even switch to a new computer. 3. The camera cannot be shared with the digital camera. The camera cannot be used as an input device with a digital camera. Analysis and processing: Some cameras come with this driver software, Videofor Windows (Windows Video) and Direct Show Device Driver (for direct display and setup drivers), which are used by digital cameras and can be used with other devices in the system (including The camera) works together as a universal video input device. So just install a camera software. 4. The color of the video pre-displayed image is abnormal. The phenomenon of the video of the newly purchased camera is not normal, but it can be restored after a while. Analysis and processing: For ordinary cameras, manual whitening is required, but the camera can be adjusted automatically. Usually wait 20 to 30 seconds, the system's autowhite (automatic whitening) function will automatically correct or balance. 5. Flower screen failure phenomenon: When using the camera, the flower screen appears. Analysis and processing: First check the driver installation and possible device conflicts. Check if the camera model matches the camera driver. In addition, you can change the graphics card test, because the camera may not be compatible with the graphics card or display driver. It is also possible that the driver is not installed correctly. If the driver cannot be upgraded by upgrading the driver of the graphics card, only the graphics card can be replaced. 6. Black screen or white screen failure phenomenon: When using the camera, a black screen or a white screen appears after the image frame is popped up. Analysis and processing: This is caused by improperly checking the software settings. This kind of problem may have to be tried many times. Please refer to the software troubleshooting manual. 7. The light of the pre-displayed image is abnormal. Symptom: Some part of the image of the camera video is too dark or too bright. Analysis and processing: You should start with the use environment and ingesting objects, such as moving away bright light sources or increasing the brightness of objects. Then adjust the brightness and contrast the background. 8. The camera cannot be shared with other video input devices. After the camera is installed, the camera is installed. So I don't know which device is working. Analysis and Processing: When using multiple video ingest devices, the computer uses the default device. However, it is not as easy to set up the default printer as the printing device in Win 9.x, and there is no easier way to determine the default device. So the best way is to choose one through a series of steps. The specific method to make a video camera driver effective is: open “ control panel & rarr; multimedia & rarr; video & rarr; device & rdquo;, open the "video intake device" list, double-click the camera name, open the dialog box, display Camera properties, and then make the driver effective as required. Symptom: A camera that was originally working on a desktop computer is not working properly when it is connected to a notebook. Analysis and processing: The camera and the graphics card are most likely to conflict. After the problem, in addition to the camera itself, you should also check the video card and try to reduce the speed of the graphics card. The method is: right click on the desktop, select “ attribute → set → performance & rdquo;, gradually reduce the hardware acceleration from the fourth file to the last file to see if it can solve the problem. If you can, gradually upgrade the grade until you find the balance point that solves the problem. 10. The image display speed is slow. Symptom: When using a digital camera to access the Internet, it is unexpectedly found that the image on the camera is displaying too slowly. Analysis and processing: This is because of the slow speed of the website or the narrow bandwidth of the ISP. Try changing to a website or using another ISP account to access the Internet. 11. PC can be used to connect to the notebook is not normal failure phenomenon: a camera that can be used normally on the desktop, after connecting to the notebook is not normal. Analysis and processing: The camera and the graphics card are most likely to conflict. After the problem, in addition to the camera itself, you should also check the video card and try to reduce the speed of the graphics card. The method is: right click on the desktop, select “ attribute → set → performance & rdquo;, gradually reduce the hardware acceleration from the fourth file to the last file to see if it can solve the problem. If you can, gradually upgrade the grade until you find the balance point that can solve the problem. This article comes from [System Home] www.xp85.com
