When you are doing a very important video chat, you find that the PC is slow, you can't run other applications at the same time, or the mouse suddenly moves hard, and your speakers are making strange noises. What should I do? When you are in a video chat, the image will be drastically changed and the color will not change properly. What should I do? When you are in a video chat, you find that your respect is distorted. Your netizen seems to look at you from the "cat's eye". What should I do? At this time, don't think that your PC has a problem, don't complain that QQ and MSN are not good. The first thing to think about is that your camera has a problem.
Let the camera serve you wholeheartedly
Choose the camera, but also use the camera to get the best results, let's see how to make the camera use its best to achieve the desired effect.
1. Camera installation and configuration
Before installing the camera, be sure to read the instructions provided by the camera manufacturer carefully and carefully to ensure that your camera is properly installed. Note: Please do not insert the camera into the computer USB interface when the camera driver is not installed! If you plug in the camera without installing the driver, when Windows prompts you to install the driver, click the "Cancel" button, and unplug the camera's USB connector, then follow the steps below to install. The correct installation of the camera is as follows: Insert the camera installation CD, follow the steps in the operation manual to install according to the computer system. At present, the general camera is USB interface, and most cameras do not need an external power supply. As long as the driver is connected, the camera can be connected to the USB port of the computer.
2. Use of camera function
After purchasing a good quality camera, the camera is properly configured, and then combined with some commonly used software, it can make it better for us and receive some unexpected results. The camera I used is a Vimicro 301 processor chip. Let's talk about how to better use the camera.
(1) Choose the appropriate working mode
Some high-quality camera processors (such as the Vimicro 301 processor) use advanced algorithms to accelerate the hardware, making the camera perform well in VGA mode and can reach 15 frames per second. 320×240 is a kind of resolution commonly used in video chat. When the camera is working, click “Options” under “AMCAP” program, select “320×240” under “Video Capture Pin...”, you can see the use. The camera of Zhongxing Micro 301 processor has outstanding image effect in CIF mode, and the image is reproduced realistically, and the speed reaches 30 frames/second.
2) Clear image quality
The quality of the image is related to the amount of exposure, which means that the DSP controls how much light should pass to enable the CMOS to get a clear image. The user can adjust the exposure time arbitrarily, such as a picture that requires a motion track, which can lengthen the exposure time. If it is necessary to create a dim effect, the exposure time should be reduced. Use the built-in Zhongxing Micro 301 processor camera as follows: When the camera is working, click the menu "Options" under the "AMCAP" program, select "Video Capture Filter...", you can use the manual exposure function, this function for some professional users It is very useful to adjust the brightness of the image as needed, allowing the user to adjust the exposure time arbitrarily to achieve the desired effect.
3) Powerful potential features
The camera can be used for both video chat and photo taking, and can be used with different software to achieve multiple functions.
a. Use ACDSee software to implement the camera function, open ACDSee 5.0, click “Get” in the shortcut button bar, then select “Twain”, call up the setting dialog box, select your own camera, and “Format, File” in the output. Clips and templates" are set. Once confirmed, the capture dialog will appear. In the "Video" preview box, you can see the appropriate photo. Click the "Capture" in the "Control" area on the right side, and the image will appear in the "Legend" area. In the legend area, select your favorite photo (double click to enlarge). Go to the directory selected by Scan Settings. The size of the captured image can be set in the "Format" of the control area, and the Ctrl jump and Shift continuous selection are supported when the image is sent.
b. Macro photography
If a stamp collector has a good stamp, it can also be photographed and saved by the camera. The method is the same as above, but the focal length of the lens should be carefully adjusted to observe the video window until the image is clear.
c. remake and processing
The camera can also take a negative. If you still have a negative, you can find it and remake it into a photo and put it into your computer to make it a VCD. The specific operation is as follows: first fix the film, meet the light (not too strong), close the camera to the film (same macro photography), and take a picture of the film. Then use ACDSee to view the picture and select "Edit", call ACD FotoCanvas to process the picture, select "Color → Negative" from the "Filter", the film will become a photo in an instant.
d. Get videos with SnagIt
Run SnagIt and select "Record a screen video." Press the capture hotkey “Ctrl+Shift+P”, use the mouse to draw the recording area of SnagIt in the video area, release the mouse, and then pop up the recording message prompt box. If there is no problem, click “Start” to record the video. Press the hotkey "Ctrl+Shift+P" again to pause or stop recording. After stopping, click the preview window. After the playback is satisfactory, you can save the recorded video as a file.
Camera maintenance
In order for the camera to continue to serve you, in the daily use, some things related to the protection of the camera must be done. Since the camera is an electronic product that is easily damaged, it must be taken care of.
1. Do not point the camera directly at the sun to avoid damaging the image sensing device of the camera;
2. Avoid contact between the camera and oil, steam, water vapor, moisture and dust;
3. Do not wipe the camera with ordinary detergent or organic solvent;
4. Never touch the lens with your fingers. If the lens needs cleaning, use a soft brush and a blower to remove the dust, then wipe it with lens paper. If you use a cardboard, paper towel, or napkin to wipe the lens, it can easily damage it.
5 Do not pull or twist the cable, as this may cause damage to the camera;
6. When not using the camera for a long time, it is best to cover the lens cover or cover the camera with a cloth. For camera users who choose to use CMOS lens, because CMOS light permeability is normal, the ambient light should not be too weak when used, otherwise it will affect the imaging effect.
