What if the new computer camera video capture does not work correctly?

Recently, a friend has assembled a new computer, but when I open the "Video Device" in my computer, "There is no video capture hardware video capture does not work correctly", I can't open the camera, naturally I can't video anymore. Later, Xiaobian went to her house and checked it out. The reason was actually very simple. Let's share it for everyone.

Computer camera video capture does not work correctly. What is the reason for no video capture hardware? How to find and solve the problem? Below, Xiaobian will share the solution for you.

1. First open the computer of my friend Win7 computer (my computer). Under other options, you can actually see the video device, but after clicking open, you will encounter the video in the above picture. The capture does not work correctly, there is no video capture hardware & rdquo; prompt, as shown.

Xiaobian originally thought that a friend's desktop computer is equipped with a USB camera, but when he entered the device manager, he did not find the “graphics device”, and then looked at the computer and found that the computer had no camera at all.

Therefore, if you encounter a computer camera that opens, the video capture does not work correctly. There is no video capture hardware prompt. First of all, if you want to see if the computer is equipped with a camera, it is not a video device in my computer. The camera is installed on the representative camera.

The device can be found in the device manager, it means there is a camera, and the driver is successfully installed.

2. If you confirm that the driver is installed in the camera, there is still no video capture hardware to open the camera. What about it? There are two main situations here.

One is that the camera is broken, or the computer's USB interface is broken (you can try to change the interface), it can't be recognized by the computer;

The second reason is that the camera driver is not correct. The installation or camera service is disabled.

If the camera driver is not installed, the user can see an unknown device with a yellow exclamation mark in the device manager. In this case, we can solve the problem by installing the driver for the camera.

The camera installation driver is very simple. You can search for the corresponding model driver to the computer according to the camera brand model, and then you can use it after installation. The other is to download and install the driver wizard or Lu master tools in the computer. These tools have the hardware driver intelligent detection function, which can detect that the camera driver is not installed, and the installation prompt can be downloaded and installed online.

There is another kind of driver is also normal, but the camera is not available, this situation is mostly due to the disabled camera-related services or conflicts with some software, you need to find a detailed exclusion, everyone You can go to the computer service to see if there is a camera-related service that does not start properly.
