Win 10 camera turns on the black screen, who knows how to solve it?

Guide to solving common problems of driverless cameras Nowadays, many cameras are unmanned cameras without driving. Advantages of driverless camera: The biggest advantage is that it is easy to use, and there is no need to install drivers. For computer enthusiasts who often redo their systems, it can save a lot of trouble. In addition, the unmanned camera has smooth picture, high resolution and good effect. Let's summarize the common sense of unmanned cameras in actual use. First, the requirements of the non-driven camera for the computer operating system: First of all, it must be clear that at present, any non-driven camera cannot be plugged and played under all operating systems. For details, please see: 1, the full version of WineowsXP SP2/Vista operating system fully supports driveless cameras, and there is no problem with plug and play; 2. The simplified version of 2.WineowsXP SP2/Vista operating system may need to install an operating system patch to make the driveless camera plug and play. 3.WineowsXP SP 1/2000 operating system, and relevant patch software must be installed to realize plug-and-play without driver. 4. Antique machines with Wineows98/Me operating system cannot use unmanned cameras. Therefore, the old machine used 98 or Me system ten years ago, so don't consider using a driveless camera! In recent years, the machine must also install the full version of XP SP2. it is quite easy to do so. Not to mention the Vista system, the effect is very good. Second, the requirements for the machine computer by using the camera without driving: the CPU frequency is required to be above 700MHz, the free space of the hard disk is 600M, and the memory capacity is 256M m ... The first two requirements can be met by ordinary computers (it should be said that the CPU of the computer installed after 200 1 can reach above 700MHz). The key point is that some computers can't reach the memory capacity of the last one, and the graphics card will crash, turn black or can't output video at all during use. Such a machine should upgrade its memory! Third, the USB interface of the computer: On the computer that supports USB2.0 interface, the video quality of the camera without driving is the best, followed by USB 1. 1. The new machine and motherboard are all 2.0 speed interfaces. When you plug the camera cable into the USB interface of the computer, if the system prompt "This device can improve performance" appears in the lower right corner of the desktop, it means that the USB interface of the computer is 1. 1. It is recommended that users upgrade to USB2.0 interface in order to obtain better video quality. In addition, it is recommended that you plug the camera cable into the USB interface on the back of the main chassis, so as to avoid the camera being unrecognizable or unstable due to the long connection of the data cable and the quality problem of the front USB interface. Fourth, the problem of the Chinese version of Direct X of the machine. It is suggested that the highest version of Direct X supported by the operating system should be installed in the machine in time to obtain good video effect. Some unmanned cameras are presented by software. Tips before installing these attached software: In order to ensure the normal use of additional functions, before installing camera special effects software, please confirm: ① Whether anti-virus software such as Rising, Norton, Jiang Min, Trend, Kingsoft and Kaspersky has been installed in the machine or whether the firewall function that comes with XP has been turned on. If it is installed or turned on, please close or exit it all before installing the driver. ② Have drivers for other cameras been installed in the machine before? If so, it is recommended to uninstall their driver and install this camera driver after restarting. Install the software after inserting the camera. Six, other questions: 1, the camera is plugged in, how can I see my local video effect? Must it be in the QQ video? A: You don't need to open QQ video. As long as you install any video tools such as VP-EYE, you can use these software to watch local video effects. 2. Why does the image turn upside down after the camera is turned on? A: Reason 1: The photosensitive chip of the camera is inverted. Although the camera is looking straight, the lens is rotated by 180 degrees. Turn it around. Reason 2: The camera program may conflict with some software in the computer, such as the video storm player software installed in the computer. 3. After the camera is installed, it can be used to watch local images in other programs, but it cannot be used in QQ video. Why? A: Possible reasons: 1. QQ video has turned off local video transmission, just turn it on; 2. No corresponding video device is selected in 2.QQ video settings, so you can choose according to the actual situation. 4. Why did you plug in the driverless camera and turn on the black screen of the video software? There is no unfamiliar hardware in the computer equipment. A: The possible reasons are: 1. Computer configuration is too low, it is recommended to upgrade; 2. Storm video is installed in the computer. It is recommended to delete or install the latest version. Common problems of cameras-white screen or black screen failure phenomenon: during use, white screen or black screen appears after the image frame pops up. Solution: Check the software settings. Solution: Please refer to the notes in the manual to change the settings. Note: such a problem may be a headache and may require multiple attempts. At this time, you will be eager for a good manual with troubleshooting. The reason may be that Preview under the Options menu is not open. Please double-click and wait for five to ten seconds. The solution of camera's black screen and white screen is 1. Can't find the fault phenomenon of the camera: a computer can't detect the newly installed camera with USB interface, or displays an unrecognized USB device. Analysis and treatment: first check the operating system, and then check whether there are errors in BIOS, USB interface and installation. If the running system is Win 95, it cannot support USB interface and must be updated to Win 98. USB device must be valid in BIOS settings. If these methods don't work, try connecting the USB camera to the second USB interface. Of course, it is also possible to install the wrong driver or choose the wrong equipment. You can check the system devices and reinstall the drivers. If an unrecognized device is displayed, it is necessary to find the reason on the USB cable. Many people use USB extension cables and USB HUB, and some cables of current USB cameras are too long, which will also lead to the inability to find devices. If there is a USB socket on the front panel of the chassis, incorrect internal wiring will also lead to the failure to find the device. When the equipment cannot be found, try to install it on the USB interface of the motherboard behind the cabinet. After normal use, connect the extension cord or the USB port in front of the cabinet. 2. The camera speed is slow, and there is a smear fault: after installing the newly bought camera on the Internet, I feel that the display speed is too slow. After changing the dialing location and ISP, the speed is still very slow. Test this camera when you are not online. At this time, the image display is also slow, with heavy smear. Analysis and treatment: This phenomenon is caused by dim surrounding light. You can increase the light source, or buy a camera with LED lighting, and the large-aperture lens can also be improved. 3. The camera can't share the fault phenomenon with the digital camera: the camera can't be used as an input device with the digital camera. Analysis and processing: Some cameras have this kind of driver software, such as Videofor Windows (that is, Windows video) and Direct Show device driver (that is, direct display and setting driver), which are used for digital cameras and can be used as general video input devices together with other devices in the system (including cameras). So, just install a camera software. 4. Abnormal color of the video preview image: The color of the video preview image of the newly purchased camera is abnormal, but it can return to normal after a period of time. Analysis and processing: For ordinary cameras, it is necessary to adjust the white manually, but the camera can adjust it automatically. Generally, after waiting for 20 to 30 seconds, the autowhite function of the system will be automatically corrected or balanced. 5. Flower screen failure phenomenon: Flower screen appears when using the camera. Analysis and treatment: First, check the installation of drivers and possible equipment conflicts. Check whether 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 this problem can't be solved by upgrading the driver of the graphics card, you can only change the graphics card. 6. Black screen or white screen fault phenomenon: When using the camera, the image frame pops up, and the black screen or white screen appears. Analysis and treatment: this is caused by improper setting of the inspection software, and this problem may have to be tried many times. It is usually caused by installing the wrong driver. For example, there are many versions of drivers in 30 1. Some drivers can be installed normally, but they can't drive CMOS, which will cause a black screen. Be sure to install the original driver. Install the driver first, don't plug in the camera. After installing the driver, insert the camera. You will be prompted to find new hardware. You can delete it, click the CD's settings and perform automatic driver installation. People who plug in the camera first and then install the driver will encounter this problem. If the brightness is adjusted too high or too low in the control panel of the camera, it will also cause a black screen or a white screen. At this point, you can click "Default" to reset to factory settings. If the camera has a lens cover, please open the lens cover to use. Long-term use of the camera in the same position against a large area of strong light will cause the photoreceptor to age and burn out. 7. The light of the preview image is abnormal: a part of the preview image of the camera video is too dark or too bright. Analysis and treatment: we should start with the use environment and intake of objects, such as removing bright light sources or increasing the brightness of objects. Then adjust the brightness and contrast the background. 8. The camera cannot share the fault phenomenon 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 multiple video capture devices are used, the computer will use the default device. However, setting the default printer is not as convenient as the printing device in Win 9 x, and there is no simpler way to determine the default device. Therefore, the best way is to choose one through a series of steps. The specific method to make the camera driver effective is to open "Control Panel → Multimedia → Video → Equipment", open the "Video Acquisition Equipment" list, double-click the camera name, open the dialog box, display the camera properties, and then make the driver effective as required. Fault phenomenon: The camera that can be used normally on the desktop is not normal after being connected to the notebook. Analysis and treatment: the camera is most likely to collide with TV cards and graphics cards. When there is a problem, we should not only find the reason of the camera itself, but also check the graphics card to slow down the graphics card as much as possible. The method is: right-click on the desktop and select "Properties → Settings → Performance", and gradually reduce the hardware acceleration from the fourth gear to the last gear to see if it can solve the problem. If you can, gradually upgrade the level until you find a balance point that can solve the problem. For TV cards, general software has a setup wizard. First, use the camera in the image device. If not, only when using the camera, first disable the TV card in the device manager. 10. The image shows Bao Gong's facial fault: when chatting online with a digital camera, the facial display is too dark, like Bao Gong, but the turnover light is still sufficient. Analysis and treatment: this is caused by the backlight of the camera lens, or the background is a large white wall. Enter the camera control interface and check "backlight compensation". The DPS of the camera also has automatic backlight compensation function, which is weighted. If the area occupied by the head in the picture is too small, or deviates from the middle position of the picture, the exposure control program will expose according to the maximum area. Try to put your head close to the camera or check "Backlight Compensation". The camera doesn't display images, and the computer camera doesn't have a white screen solution. The camera doesn't display an image, so you can't restart the camera and reinstall the software. Check the machine; Either plug in the usb plug again, or hang up and restart. If the image is too bright or too dark, adjust the brightness and contrast background; Under normal circumstances, qdi digital camera will automatically adjust the exposure according to the ambient light to display normal brightness; If there is a bright light source or uneven brightness in the environment, it will lead to false exposure, so it is necessary to increase the brightness of the object, or don't directly check the following problems against the bright light source: 1, cable problem, virtual welding. . . 2. Power supply problem, insufficient power supply and insufficient current. Replace the transformer. 3. There are many ways to monitor the terminal problem on the Internet, but there is a common problem on the Internet in China, that is, all people only know plagiarism and don't try, and none of the methods they have been looking for for for a long time are useful! ? In fact, my solution is very simple, just reinstall the driver! However, there is a premise that the original driver must be deleted, otherwise it will be useless! Many people have this problem, which is usually caused by installing other software by mistake, so after reinstalling, the driver can correctly associate the application software! Carefully delete the original driver, and restart where it should be restarted! Promise to solve the problem! VISTA is also useful. (My least favorite system! Other solutions: First, uninstall your original program uninstallation method: right-click my computer-properties-hardware-device manager or directly press Ctrl+F 1, then open the universal serial bus controller and delete all the "Usb root hubs" below. In addition, open Add and Remove Programs in Control Panel. Are there any camera applications, such as vm30 1? Uninstall 2 and restart it. After restarting, you will find new hardware. Don't choose automatic installation, then click "Next", then check "Search floppy disk and CD", and check everything else. And play the CD, don't install the driver from the CD. Let the system search automatically. So that the installation can be successful. 1. The reason why the driver is not easy to install is 1. At present, there are many popular versions of ZTE micro-camera drivers on the market, and many users leave junk files in the system registry during the process of installing and uninstalling the drivers, which makes it difficult to install the drivers later. 2. At present, there is a cloned operating system on the market, which integrates the old versions of ZTE Micro and WHQL drivers. When the user installs a newly bought camera or updates the latest driver, the camera cannot work normally; Method 1: Automatic Unloading Method Step 1: Click the corresponding driver's unloading in the start menu. (It is possible that the uninstallation function has been damaged, and it can be uninstalled by installing a new driver. The system will uninstall the old driver first, and the purpose can be achieved. Step 2: Before installing the new driver, select the following corresponding executable file in the attachment: FOR_XP_ME_98. EXE for Windows XP/ME/98 FOR_Win2K。 EXE for Windows 2000 (Note: this tool requires that the default path of the system is disk C to be effective. If an error dialog box appears under the Windows ME/98 operating system, it means that the system is clean and the tool will not damage the installed driver. ) the third step. Install a new driver method. Step two. Manually uninstall the method. Step one. Select "Select all files and folders, and then go to the C:\Windows\inf folder to save all OEM files (such as oem0). )Oem 1.inf，Oem 1。 PNF ...) Cut and transfer to another directory to save or manually delete the OEM file corresponding to the camera. Step 2: After completing the above steps, insert the USB camera. At this time, the computer will find new hardware and pop up the information of installing drivers, select Cancel, then right-click my computer, select Properties, and enter the system properties in the pop-up system properties interface-Step 3: Unplug the camera and start installing new drivers. In view of the above second phenomenon: Step 1, the cloned operating system saves the camera driver in the folder C: \ Windows \ driver \ camera \ 301p by default. When you click on the new camera driver CD to install, the system will not prompt that there is already a camera driver and uninstall it. Please find this folder and delete it. The second step is to install a new camera driver, then plug in the camera to load the hardware, and restart the computer after the installation is completed, so that it can be used normally; Step 3, click the new CD to install the latest driver without repeating the above two steps. After the camera is plugged in, the system detects the new hardware and automatically finishes loading the hardware driver. Step 4, enter the device manager, and you can see that the image processing device has been successfully installed, but when you open the "AMCAP" preview image, there will be no preview, white screen or black screen; Step 5, put the right mouse button on "Vimicro USB PC Camera (ZC0301PL)" of the image processing equipment to update the driver. When the dialog box appears, select Install from a list or a specified location. After step 6, select "Do not search" to enter the "Install from floppy disk" interface. Step 7: Click Browse and point the path to "usbvm3 1b.inf" in the CD directory of the drive or the latest drive directory. Step 8: Click "Next" all the time to complete the driver installation. I hope you can succeed! ! ! ! !
