How to adjust the blur of mini camera?

Photographic blur, how to solve it?

If the camera function of the mobile phone is blurred, we suggest that you:

1. Check whether the camera lens is clean and wipe it gently with a clean soft cloth.

2. Check whether the lens is worn.

3. Check whether the focus is accurate; Don't shake the phone/tablet at the object to be photographed.

4. Adjust the camera resolution.

5. Check whether the camera is set to an inappropriate shooting mode and reset the camera. Try: Camera-Settings (Pinion)-Reset.

6. If you are in a dark environment, it is recommended to turn on the flash function of the mobile phone or manually add auxiliary lighting equipment to take pictures.

If the problem still exists, it is recommended that you take the purchase invoice, maintenance card and machine to the local Samsung after-sales service center for testing.

The camera is blurred. What should I do?

If you use a Huawei mobile phone and the camera on the back of the phone is blurred, you can check the operation by the following methods:

First of all, ensure that the camera's focusing function is normal.

Select the professional mode, aim the camera at the subject, adjust the shooting distance (about 0.5m below 3X and about 2m above 3X) according to different multiples, select MF (manual focusing) as the AF parameter, and drag the slider left, right and back to observe the preview interface.

1. If the preview changes from clear to fuzzy, and then from fuzzy to clear, the camera's focusing function is normal. Please continue the investigation according to the following situation.

2. If the preview interface is always fuzzy, it may be that the focusing function of your mobile phone is not normal. It is recommended that you back up important data in advance (third-party applications such as QQ and WeChat need to be backed up separately), and bring the purchase voucher to the nearby Huawei customer service center for more help.

Second, make sure that the camera and laser sensor are not blocked.

Make sure that the camera lens and laser sensor are not blocked by foreign objects. Protective film, three-way protective cover or other obstacles may interfere with the sensor. Test the camera without installing the above items to see if the problem is caused by these items.

Third, be sure to shoot after the focus is completed.

1. When taking a picture, click on the subject with your finger to focus manually, and don't click the shutter button until the focus frame disappears, because this means that the camera has not finished focusing.

2. If you focus manually when recording video, the camera will lock the focal length to avoid unclear or unstable images when the mobile device changes the scene or position. You may need to manually refocus the camera again. To make the camera focus automatically, please avoid manual focusing when shooting video.

Fourth, make sure to use the default zoom factor.

If you focus manually when recording video, the camera will lock the focal length to avoid unclear or unstable images when the mobile device changes the scene or position. You may need to manually refocus the camera again. To make the camera focus automatically, please avoid manual focusing when shooting video.

Fifth, be sure to keep the phone stable when shooting.

If your subject moves quickly, or your mobile phone keeps moving during shooting, the camera will not focus properly, and photos or videos may be blurred. It is recommended that you hold your mobile phone steady when shooting and use a tripod if necessary.

6. Make sure to shoot at a reasonable distance.

Due to the shallow depth of field, some mobile phone cameras may not be able to focus correctly when taking close-up photos.

1. When using the large aperture mode, make sure that the subject is at least 20cm (8 inches) away from the phone and in the center of the screen.

2. When using the super macro mode, please keep the distance between the mobile phone and the subject at 2.5- 10 cm.

3. When shooting with telephoto, please keep the distance between the mobile phone and the subject at least 2 meters.

Seven, other special mode shooting skills

1. In night mode and streamer shutter mode, the camera needs a long exposure time, so any movement of the camera or the subject may lead to unclear photos or videos. Please keep the phone stable when shooting, and use a tripod if necessary.

2. Large aperture or portrait mode will automatically blur the background [f3] and make the subject stand out. Background blur is normal in this shooting mode, please feel free to use it.

If you are still confused after trying the above contents, please contact Huawei's customer service hotline (950800), or back up your important data in advance (third-party applications such as QQ and WeChat need to be backed up separately), and bring the purchase voucher to Huawei's customer service center for further help.

1, check the image quality you set in the camera. If the setting is low, you will record low-resolution video. You can't see the difference on the camera because the screen is small, but it's easy to compare on the computer because the screen is big. And the effect originally put on the computer is not as clear as that seen on the camera.

2. Generally, it can be recorded when the outdoor light is good, and the video image will be noisy when the indoor light is bad, and the image will be unclear accordingly.

It may be that your camera's original performance is average and its pixels are low, not that the machine itself has any quality problems.

I don't know whether your camera is analog or digital. If it is digital, the quality of the recorded video file should not be lost. If it is analog tape recording, it will be collected by the acquisition card, of course, there will be a loss of image quality, and the video acquisition card can set the format during the acquisition process, which will also affect the clarity. Also, whether the video editing software supports high-definition acquisition.

Finally, you can check whether the focus position of the image behind the camera is adjusted correctly, whether the focal length of the lens is adjusted correctly, whether the lens surface is clean (if there is dust or fingerprints on the lens, it will definitely affect the image quality), whether the computer monitor is adjusted correctly, and whether the display surface is clear and clean.

What if the camera image is not clear?

There are many reasons why the image is unclear: first, determine whether your video source is analog or digital.

Analog video signal analysis;

1, the hardware itself, because the clarity of the image has a lot to do with camera parameters and lens focal length. If the focal length of the lens is 3.5mm and the CCD is 1/3, then the sight distance is more than 5 meters, and if it is beyond the shooting range of your camera, the image will naturally be unclear.

Lens focal length: 2.8mm, 3.5mm, 4mm, 4.8mm, 6mm, 8mm,12 mm.

CCD viewing angles: 86.3, 67.4, 62, 52.2, 42.3, 32.6, 22. 1.

Object distances: 4.3m, 5.4m, 6m, 7.3m, 9m, 12m, 18m.

In this case, it is necessary to adjust the monitoring distance of the camera, and only when it is adjusted to its focal length range can the best effect be achieved.

2. If it is clear during the day and not clear at night, it means that the light source at night is not strong enough, which is also related to the minimum illumination of the camera. In this case, you can only replace the camera or strengthen the night lighting. If the camera is an infrared camera, you can also add an infrared light to make up for the lack of light at night.

3, line interference, the image of the analog signal is not clear. If it is a horizontal image, it means that the video signal has been disturbed. This situation can only be solved by finding the interference source and keeping the signal line as far away as possible.

Digital signal analysis:

The resolution and clarity of 1. digital signal can be set by software, but it mainly depends on the parameters of the front camera.

2. The loss of encoder and decoder in video image processing will also lead to unclear images.

3. The camera and circuit problems are consistent with the analog signal analysis.

Summary: The camera's own parameters, camera's uncleanness, line interference, weak interface welding, codec matching, soft decoding, display resolution and other reasons will lead to unclear images, so it is suggested to analyze the reasons before solving them.

What is the blur of the picture taken by the camera and how to adjust it?

The reason why the camera photos are blurred:

1: insufficient light. Shoot when the light is sufficient, so that you can use a higher shutter speed and avoid blurring the photo;

2: Shutter speed is too low. When the light is not very good, you can appropriately increase the ISO sensitivity of the camera to increase the shutter speed, or you can use the built-in flash to make up the light.

3. The ambiguity caused by shaking hands. When shooting in hand, you can turn on the anti-shake function of the camera (if you have this function);

4: If possible, please use a tripod to stabilize the camera to avoid blurring the photos.

5: There is something wrong with the equipment. This can only be repaired.
