Reason Analysis:

The causes of such problems are summarized in four main cases

1, Camera driver installation error:

The current shipment of machines, most of the same model may be the use of multiple manufacturers of camera equipment, the official website provided by the driver is all the driver packaging, so do not rule out the user will install the wrong situation.

2, informal retail or Lenovo OEM system caused driver load error:

Especially for some drive-free camera devices, if customers install informal retail or Lenovo OEM system, such as Ghost system, compact system, integrated drive system, etc. can easily lead to driver load error.

3, System problems

4, the camera hardware itself problems

To sum up, the root cause of this type of problem is that the faulty camera driver is loaded, and the hardware itself is rarely a problem. Therefore, priority should be given to the elimination of drivers.

Solution:

Scenario one (for 1, 22 cases in causal analysis):

Instruct the user to download the corresponding driver installation according to the host number to the website and confirm the installation is successful.

XP system driven self-recognized state

State of Win7 WIN8 system driven by self-recognition

The state of the installer driver (v470c win7 System for example)

Programme II (For Causal Analysis 3):

You can choose to install a genuine system or an OEM system test.

Programme III

Most of the current shipments of notebook models, are pre-installed YouCam software This software can facilitate the implementation of some video effects, camera personality settings, etc., can also be adjusted through this software. Take YouCam 3 As an example to manipulate the following figure,

Click on the top right corner wrench shape Settings button, the Settings Interface dialog box, to remove the "horizontal flip" or "vertical flip" option, you can solve the corresponding problem.

If there is a problem in the QQ video chat, press the following figure to select "CyberLink Webcam" video equipment.

In addition, the early models (basic warranty) may be pre-installed Easycapture software, set the following figure to Easycapture 2.5 For example, click "Camera Settings", remove the appropriate options.

Programme IV (For causal analysis 4)

To troubleshoot the software problem, we can change the camera test.

Note:

If you encounter this type of problem, follow these steps:

1, the installation of the official website of the corresponding driving test, if necessary, the installation of genuine or OEM system testing

2, if the drive and system inconvenience operation, the use of Third-party software such as YouCam, Easycapture and other debugging

3, excluding the above two points and then consider the hardware problem
