How to turn on the camera of desktop computer 1:

1, XP system, double-click to open my computer, and click USB video device.

2. After installing ATK and LifeFrame in Win7, use Fn+V to call the camera, or use some video chat software. Also, make sure that the camera driver is installed.

Right-click my computer and select Manage. There is a "device manager" in it to see if there is that "video device" in it, that is, there is a driver; Just open the video directly when using it.

Method 2 for opening the camera of desktop computer:

Under 1 and xp systems, the system will directly display the u *** video device as a system icon. This picture can be found in my computer. Click the photo button on the left to take a photo. This is the easiest way.

2. There is another way to use the camera. It's in the attachment of the start menu. There is an option for scanner and camera. Click to enter u *** camera management. Just click on the photo like the above operation.

3. Of course, the camera function of the system is not powerful. If you need more kinds, such as taking pictures regularly, you can use software to realize the function. The specific software can be selected by yourself. The win7 system itself does not have the function of turning on the camera, and it needs a driver or software to realize it. For example, download a greener software online.

4. Run the software, and then click to open the camera. At this point, a camera icon is created on the desktop. Click the icon to enter the camera.

5. By executing this function, you can realize the function of shooting or taking pictures. This is just the simplest win7 camera software. Basically do not realize any complicated functions. If you want to be strong, you can download some professional software. For example, Meitu Xiu Xiu.

1, image resolution/resolution ● SXGA 1280x 1024 is also called 1.3 million pixels.

SVGA800x600 is also called 500,000 pixels.

The latest Oni camera

VGA640x480 is also called 300,000 pixels, and 350,000 pixels means 648X488.

CIFS 352 x 288 is also called 65438+ megapixels.

2. Image format/color space

RGB24 24,420 are the two most commonly used image formats.

RGB 24:R, G and B have 8 bits each, which can represent 256 colors at most, so that 256*256*256 colors can be reproduced.

I420: One of YUV formats.

Other formats are: RGB565, RGB444,

3. Automatic white balance adjustment AWB

Definition: It is required to illuminate white objects in different color temperature environments, and the image on the screen should also be white. Color temperature represents spectral components, the color of light. A low color temperature means that there are many long-wave light components. When the color temperature changes, the proportion of red, green and blue in the light source will change, and it is necessary to adjust the proportion of the three primary colors to achieve color balance, which is the reality of white balance adjustment.

4. Image compression mode

JPEG: Joint Graphics Expert Group still image compression method. A compression method for lossy images. The greater the compression ratio, the worse the image quality. This format can be selected when the image accuracy is not high and the storage space is limited. Most digital cameras use JPEG format.

5, color depth color digits

What reflects the color recognition ability and color expression ability of imaging is actually the quantization accuracy of A/D converter, which refers to how many grades the signal is divided into. Commonly used color bit representation. The higher the color depth, the more beautiful and moving the color of the image. The number of cameras on the market has reached 24, and some even reached 32.

6. Image noise

Refers to the noise interference in the image. It shows that there are fixed color points in the image.

7. perspective

It is the same principle as human eye imaging, which is simply the imaging range. It has something to do with the lens used

8. Output/input interface

Serial port RS232/422: the transmission rate is slow, which is115kbit/s.

Parallel port PP: the speed can reach1mbit/s.

IrDA: The speed is also 1 15kbit/s, which is quite common in notebook computers.

Universal serial bus USB: plug and play interface standard, supporting hot plug. The rate of USB 1. 1 can reach 12mbit/s, and the rate of USB 2.0 can reach 480mbit/s.

The IEEE 1394 firewire interface is also called ilink: its transmission rate can reach 100 m ~ 400 mbit/s?
