Hello everyone, Lin Fei to answer the above questions, notebook camera how to open Lenovo, notebook camera how to turn on many people do not know, now let's take a look!

Abstract: what if the computer camera can't be opened? Why can't the computer camera take pictures? How to solve the problem that the QQ camera cannot be used? Today, Bian Shaw will give you a detailed answer to the causes and solutions of various computer camera failures.

[laptop camera] how can the laptop camera turn on the computer camera that doesn't open?

What if the computer camera doesn't open?

First, the Win7 camera cannot be used.

Malfunction: the camera can be used normally in Windows XP system, but can not be used in Windows 7 system. The camera itself is a driverless product, although it can not be used, but the equipment can be found in the system. What is the reason, please?

A: driver-free camera, its chip has integrated the driver of Windows. If your camera does not have an integrated driver for Windows 7, your camera will not work.

The Windows 2000/XP/Vista driver cannot be used in Windows 7. Solutions are as follows:

Ask the manufacturer for the latest firmware of the camera chip. If the latest firmware program supports Windows 7, you only need to upgrade the firmware of the camera chip.

Second, the computer camera cannot be used.

There may be two reasons for this phenomenon. One is that your camera driver is not installed correctly, and the other is that there is a hardware failure in your USB interface. Currently, most camera drivers are built into Windows XP/Vista and Windows 7 operating systems. However, due to the rapid development of product technology, some new cameras may have to reinstall their own drivers before they can be used properly. Therefore, it is recommended that you first install the driver that comes with the camera set you bought to see if it can solve the problem.

If there is nothing wrong with the driver, the USB interface may be faulty. First, connect the camera to a USB slot to see if it can be used properly. If it can be used in other slots, there is something wrong with your original USB slot. If it still doesn't work, there may be something wrong with the USB interface of your camera. It is recommended to send for repair or replacement.

Third, computer cameras cannot take pictures.

I bought a new camera with a camera, but I can't take pictures. I can take pictures with the old ones. What's the reason?

Solution 1:

It is recommended to reinstall the camera software. Go to the camera's official website to download the driver, install the corresponding photo software, and you can take pictures.

Solution 2:

Click start to enter regsvr 32 quartz.dll, and the problem is solved!

It is the library file for DirectShow in quartz.dll DirectX. Most of the playback problems of streaming media can be solved after registration (when playing streaming media, the decoder can not be found).

Uninstall Storm Player and other network players.

Fourth, the laptop camera cannot be used.

Glitch: my laptop has its own camera, which used to be fine. But today I reinstalled the operating system, using ghost XP sp3. After installing it, I found the camera screen black. I don't know how to solve it. Please give me some suggestions!

Answer: there is something wrong with the driver. Generally speaking, the ghost version of the operating system is intelligently identified and driven. As long as the chip model is similar, it will automatically install it for you. But the camera that comes with the notebook is generally different from the camera on the market, so it is only natural that there is something wrong with the driver.

Solution:

1. Look at the brand and model of your laptop.

two。 Go to the official website, a laptop brand.

3. Download the driver for this laptop camera.

4. Reinstall the driver, restart the computer, and then resolve the problem.

5. The reason why notebook computer can't have built-in camera and its solution

1. Uninstall your original driver.

Uninstall method: right-click my computer-Properties-hardware-device Manager or press Ctrl F1 directly, then open the USB controller and delete all the Usb root Hub below.

That is, open add and remove programs in the Control Panel. Are there any camera apps like vm301 to uninstall?

two。 And then restart. After rebooting, new hardware will be found. Do not choose automatic installation at this time, then click "next", and then check "search floppy disk, CD", and remove all other ticks. And put on the CD, do not install the driver from the CD. Let the system search automatically. This will make the installation successful.

The reason why the intransitive verb driver is not easy to install

1. At present, there are many popular versions of ZTE micro-camera drive on the market. Many users leave junk files in the system registry during the process of installing and uninstalling drivers, making it difficult to install drivers in the future.

two。 At present, there is a clone operating system on the market, which integrates the old version of Zhongxingwei and is driven by WHQL. When the user installs the newly purchased camera or updates the latest driver, the camera does not work properly.

Method, automatic unloading method

The first step. Click uninstall the appropriate driver in the start menu. (if the uninstalled function may have been broken, you can uninstall it by installing a new driver. The system will uninstall the old driver first, and it can also achieve its goal.)

Step two. Before installing the new driver, select the following appropriate executable in the attachment:

FOR_XP_ME_98 . EXE is used for w

FOR_Win2K.EXE for Windows 2000

(note: this tool requires that the default path of the system is disk C to be valid. If an error dialog box appears under the Windows ME/98 operating system, the system is clean and the tool will not cause harm to the drivers that have been installed.)

Step 3, install the new driver.

Method 2. Manual unloading method

Step 1. Select hidden files and folders to "Show all files and folders" in my computer-tools-folder options-View.

Then go to the C:Windowsinf folder and put all the OEM files (such as oem0.inf,oem0.pnf;oem1.inf,oem1.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, then the computer will find the new hardware and pop up the information about installing the driver, select cancel, then click on my computer with the right mouse button, select properties, in the pop-up system properties interface, enter the system properties-hardware-device manager and press the right mouse button to uninstall the PC CAMERA with an exclamation point.

Step 3, unplug the camera and start installing the new driver.

In view of the second phenomenon mentioned above

Step 1. To clone the operating system, the camera driver is stored in the C:WindowsDriverCamera301P folder by default. When you click on the new camera driver CD to install, the system will not prompt that the camera driver already exists. Uninstall this driver, please find and delete this folder

Step 2: install the new camera driver first, then plug in the camera to load the hardware, and then restart the computer after the installation is completed.

Step 3. Without repeating the above two steps, click the new CD directly to install the latest driver. After plugging in the camera, the system detects the new hardware and automatically completes the hardware driver loading.

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 and black screen.

Step 5. Place the right mouse button on the "Vimicro USB PC Camera (ZC0301PL)" of the image processing device to update the driver, and select "install from the list or specified location" after the dialog box appears.

Step 6, select the next step and select "do not search" to enter the "install from floppy disk" interface.

Step 7: click Browse to point the path to "usbvm31b.inf" under the driver CD directory or the latest driver directory.

Step 8: always click "next" to complete the driver installation.

VI. Camera QQ cannot be used.

First, open any dialog box. Find the row of buttons at the top of the dialog box under the other party's nickname and signature.

The first one is video.

Take a closer look at this row of options. (as shown below:)

There is a downward arrow to the right of each icon (as shown on the right)

Click the arrow in the image above. Remember, it's an arrow, not an icon (an arrow is actually an option).

Find the vertical text to the right of the image above.

Find the option under the text "Please select your video device" (only one image and only options to choose from)

After clicking on, two options appear: "disable" and "USB video device".

Switch to "USB Video device" and the image will appear. Click OK.

If it's still dark. You can click "picture quality adjustment" to change the picture quality.

7. The camera cannot be used. FAQ:

1. Camera not available: camera not found

Malfunction: the newly installed USB camera cannot be detected by the computer.

The expert replied: check the operating system first, and then check the BIOS, USB interface and installation for errors.

Windows 7/Vista/XP/2000/2003/2008 supports the USB interface. The USB device must be made valid in the motherboard BIOS settings. If these methods do not work, try connecting the USB camera to another USB interface. Of course, it is also possible to install the wrong driver or select the wrong device, you can view the system device and reinstall the driver again.

two。 Camera not available: black screen or white screen

Failure phenomenon: when using the camera, after the image frame pops up, there is a black or white screen.

The expert replied: this is due to the improper setting of the check software, this kind of problem may have to be tried many times, you can refer to the troubleshooting manual of the software.

3. The camera doesn't work: the light in the preview image is not normal.

Malfunction: some part of the camera video preview image is too dark or too bright.

The expert replied: we should start with the use of the environment and the intake object, such as moving the bright light source or increasing the brightness of the object. Then adjust the brightness and contrast the background.

4. Cameras cannot be shared with other video input devices

Malfunction: after installing the camera, the camera is installed again. So I don't know which device is working.

The expert replied: when multiple video devices are used, 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. Therefore, the best way is to choose one through a series of steps. The specific way to make a video camera driver effective is to open the "control panel → multimedia → video → device", open the "video intake device" list, double-click the name of the camera, open the dialog box, display the camera properties, and then make the driver effective as required.

5. Cameras cannot be shared with digital cameras

Malfunction: the camera cannot be used as an input device with a digital camera.

The expert replied: some cameras have this kind of driver software, Videofor Windows (that is, Windows video) and Direct Show Device Driver (that is, direct display and setting driver). It is used for digital cameras and can be used as a general video input device together with other devices of the system (including cameras). So all you have to do is install a camera software.

6. Abnormal color of video preview image

Malfunction: the color of the video preview image of a newly purchased camera is abnormal, but it can return to normal after a period of time.

The expert replied: for ordinary cameras, manual whitening is needed, but the camera can be adjusted automatically. Usually wait for 20 to 30 seconds, the system's autowhite (automatic whitening) function will automatically correct or balance.

7. Camera does not work: blurred screen

Malfunction: a blurred screen appears when using the camera.

The expert replied: first check the installation of the driver and possible device conflicts. Check to see if the camera model matches the camera driver. In addition, you can test with another video card, because the camera may not be compatible with the video card or display driver. It is also possible that the driver is not installed correctly, and if you cannot solve this problem by upgrading the driver of the video card, you can only replace the video card.

8. A camera that used to work on a desktop is not normal when connected to a laptop.

The expert replied: the camera and the graphics card are most prone to conflict. When there is a problem, in addition to finding the reasons of the camera itself, we should also check the graphics card and try to slow down the speed of the graphics card. The method is to right-click on the desktop, select "Properties → set → 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 raise the level until you find the balance that can solve the problem.

9. Camera not available: image display is slow

Malfunction: when surfing the Internet with a digital camera, I accidentally found that the display speed of the image on the camera was too slow.

The expert replied: this is because the website is slow or your Internet speed is too slow, you can try to change the website or use 4-8MB ADSL to surf the Internet alone.

10. The camera doesn't work: the camera is slow

Malfunction: after installing the newly bought camera on the Internet, I feel that the display speed is too slow. I use the ADSL of 4MB bandwidth, but the speed is still very slow. When I tested the camera when I was off the Internet, I found that the image display was also very slow.

The expert replied: this phenomenon is caused by the low performance of the computer, you can change the graphics acceleration card, if not, you have to upgrade the CPU, memory, motherboard and graphics card, or even get a new computer.
