How to solve the camera lens blur

what if the camera image is not clear?

problem phenomenon 1: it is normal during the day, and it becomes blurred at dusk and at night

cause of the problem: in the above two groups of pictures, the focal length and focus position of the camera have not changed, but the aperture is small during the day and the depth of field is large, while the aperture is large at night and the depth of field is small. The position that is clearly focused during the day may have fallen out of the depth of field at night, and this phenomenon appears. Because it is caused by the change of aperture, this problem usually appears on the camera with automatic aperture.

solution: after setting the camera to manual (electronic) aperture, adjust the lens to focus clearly, and then restore the camera to "automatic aperture" mode.

problem phenomenon 2: the image is half clear and half blurred, commonly known as "half paste"

problem cause: the sensor is not completely horizontal when it is installed in the factory, resulting in a distance difference between the front and rear, and a distance difference of only a few millimeters may be displayed as "half paste".

solution: to completely solve the problem, we can only repair it.

For the bolt with external lens, we can reproduce the focus, improve it appropriately, distribute the blurred part to both sides, or adjust the blurred part to a relatively inconspicuous angle, such as a single color plane.

problem phenomenon 3: the external lens of the bolt can't be focused clearly by adjusting the lens focusing knob.

Cause: the external lens of the bolt, the interface of the camera is CS, just normally cooperate with the lens connected with CS interface. If the lens interface is C, a C/CS adapter ring needs to be added.

solution: confirm the interface type between camera and lens, and use the adapter ring correctly.

problem phenomenon 4: the whole image is blurred, and the definition is insufficient

problem reason: the image is either obviously blurred, not out of focus, or has a feeling of being blurred as a whole. In this case, it is necessary to consider whether the resolution is insufficient.

1) A high-definition network camera is equipped with a standard-definition lens

2) A large target lens is used in a small target camera, and the larger the target surface of the lens is not the better.

solution: the high-definition camera is equipped with a high-definition lens, and the target size of the lens is not less than that of the camera sensor, preferably close to it.

problem phenomenon 5: the ball machine is normal at a long distance, and the focus of the object at a short distance is unclear and fuzzy

Cause: The ball machine is usually monitored at a long distance, so the ball machine has the latest focus limit by default, and does not focus within the limit.

solution: according to the specific scene, adjust the distance of the minimum focus limit of the ball machine

the network ball machine can log in to the ball machine on the web page, configure it, configure it in an advanced way, and set the minimum focus limit in the image.

simulate the ball machine, enter the ball machine menu, system settings, movement settings, and adjust the minimum focus limit.

problem phenomenon 6: the image is partially or completely blurred in rainy days

cause of the problem: rainy days or humid air, rain wets the outside of the glass cover or water drops condense inside the glass cover, and all you see through the lens is blurred images.

solution: first, distinguish whether it is wet outside or foggy inside. If it is wet outside by rain, it is normal, and it will be normal after the weather is clear, or use equipment with wiper function. If there is internal fog, which is related to the installation and construction, you can check the shield and return the ball barrel machine to after-sales inspection.

problem phenomenon 7: the image is partially blurred due to the dirt on the camera cover

problem cause: the camera cover is dirty for a long time, which is out of the depth of field, and what you see is partial blur, or there is a spider web on the camera cover, and when infrared light comes back at night, you see many stripes or a piece of white.

solution: clean the camera cover regularly as required.

If the camera behind the Huawei mobile phone you are using is blurred, it may be caused by problems such as dirty lens, abnormal camera focus and camera shake. It is suggested to check according to the following operation steps:

1. Please check whether the lens is covered with film, dirt or obstructions

If the original protective case inside the non-mobile phone box is used, or there is film on and around the camera. It will affect the light transmittance and focusing function of the camera, and it is prone to such anomalies as glare, blur, inaccurate focusing and macro recognition.

please remove the protective case and film, wipe the camera and its surroundings in one direction with a clean soft cloth, and then confirm whether the shooting is clear after restarting the mobile phone.

2. Please take photos after focusing

When taking photos (videos), you can click on the screen to focus. If the preview interface changes from fuzzy to clear, the focusing function of the mobile phone is normal. If the preview interface is always blurred, it may be that the focusing function of the mobile phone is abnormal. It is recommended to back up important data in advance (WeChat /QQ and other applications need to be backed up separately) and take the purchase certificate to Huawei Customer Service Center for testing.

3. Please keep the phone stable when taking pictures

Keep the phone stable when taking pictures. Especially when taking photos (videos) at a long distance, please use an appropriate zoom factor. The larger the zoom factor, the smaller the viewing angle of the picture, the larger the subject, and the more sensitive it will be to environmental jitter. If it is in a fixed state, it is recommended to use a tripod, and if it is in a moving state, it can be used with a pan/tilt, which can achieve good stability. Turn on "Timed Photo" in the photo setting to avoid the jitter caused by clicking the screen instantly. You can also plug in headphones and use the volume button to control shooting.

4. Please keep a certain distance. When shooting close range

When taking ultra-close photos (videos), it is recommended to keep it above 1cm, and then manually click on the screen to focus and finish shooting. Using the super macro function, you can take more detailed photos at close range.

Ambient light is not sufficient and blurred, and insufficient light during photographing or video recording may also lead to blurred imaging effect. It is recommended to turn on the flash or use night scene mode when taking pictures or videos.

5. Please confirm whether the photos are blurred for night view and super night view mode

Some modes in the camera need a certain time to complete, such as night view and super night view mode, and the exposure time is long. If the mobile phone shakes or the subject moves, the photos will be blurred. Please ensure that the mobile phone is stable during shooting (tripod is recommended for fixed shooting), and then move the mobile phone after shooting is completed.

6. Please confirm whether the picture is blurred in large aperture or portrait mode.

Large aperture or portrait mode will blur the background of the picture, so some pictures are blurred, which is a normal blurring effect. If you don't need the background blur effect, you can switch to other modes to take pictures.

7. Please confirm whether it is blurred to take pictures through the glass

When taking pictures through the glass, the laser focusing detects the existence of the glass, which may focus on the position of the glass. Because the glass is close, the camera automatically switches to macro mode to take pictures. This phenomenon is normal and can be used with confidence. If the macro mode is recognized, it is recommended to turn off the macro mode and try manual focusing shooting in the normal photo mode.

if the problem is still not solved after trying the above methods, please back up important data (QQ, WeChat and other third-party applications need to be backed up separately) and take the purchase certificate to Huawei customer service center for testing. You can inquire about the Customer Service Center through the following link: Customer Service Center

What should I do if the camera of the mobile phone is blurred?

If you are using a Huawei mobile phone, it is suggested to check according to the following operation steps:

First, please keep the camera and laser sensor from being blocked

If the photos or videos taken by the camera of the mobile phone are blurred, the camera lens or laser sensor may be blocked by foreign objects.

The protective film covering the rear camera (including transparent protective film) may affect its performance, which may lead to lens flare, ghost or blur when shooting in low light.

if the device uses laser focusing, TOF sensor focusing and 3D depth sensor to measure the shooting distance, the protective film, three-way protective cover or other obstructions may interfere with the sensor. As a result, the camera will not be able to focus correctly, and the image will be blurred and unclear. Before using the camera, please tear off the camera protective film (including transparent protective film), clean the lens and sensor with a soft cloth, and use Huawei's official protective cover.

note: you can search for the corresponding product model in official website or my Huawei APP, and view the corresponding specifications and parameters of the rear camera.

second, please check whether the camera can focus correctly

if the camera is too far or too close to your subject, the pictures and videos may be blurred.

please check whether the camera can focus correctly. For example, when taking a distant photo, touch the viewing frame and focus on the distant object. When shooting close-ups, please put the phone at least 1cm away from the object to be photographed, touch the viewfinder to focus, and do not use zoom. If the image in the viewfinder becomes clearer during this process, it means that the camera of the device can focus correctly.

if the camera can focus normally, but the pictures and videos are still blurred, please find different scenarios and solutions below.

if the camera can't focus normally, please back up your important data and take the purchase certificate to Huawei customer service center for further help.

Third, please confirm the focus before shooting

If you touch the viewfinder to focus manually while taking a picture, please don't click the shutter button until the focus frame disappears, because this indicates that the camera has not finished focusing.

if you click the viewfinder when shooting a video, the camera will lock the focal length to avoid unclear or unstable images when moving the device to change the scene or position. You may need to touch the viewfinder again to manually refocus the camera. To make the camera focus automatically, please avoid touching the viewfinder when shooting video.

Fourth, it is recommended to use the default zoom factor

When taking pictures with high zoom, the mobile phone will switch to digital zoom, and the camera will be more sensitive to slight movement. Therefore, the image may appear blurred. It is suggested to reduce the zoom factor or use the default zoom factor (the solid white dot on the zoom bar on the right side of the viewfinder is the default zoom factor).

5. Please keep shooting steadily.

If your subject moves fast, 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 during shooting and use a tripod if necessary.

if you are trying to capture a moving object, please hold down the shutter button to take a photo of continuous shooting, and then select the best photo. Continuous shooting is only available when the resolution is set to 2MP or lower.

Sixth, you can move the shooting distance appropriately

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

using large aperture lenses allows more light to enter, but they have a shallow depth of field. When using this kind of camera, please make sure that the object is at least 2 cm (8 inches) away from the mobile phone and located in the center of the frame.

if your device supports super macro mode, please keep the distance between the phone and the subject at 2.5-1cm when using it.

VII. Shooting skills in special camera mode

In night mode and streamer shutter mode, the camera takes 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 during shooting, and use a tripod if necessary.

large aperture or portrait mode will automatically blur the background and make the subject stand out. The background blur in this shooting mode is normal, so please feel free to use it.

if the problem is still not solved after trying the above methods, please back up your important data (QQ, WeChat and other third-party applications need to be backed up separately), and take the purchase certificate to Huawei customer service center for further help.

how to adjust the photo blur?

If you use a vivo phone, you can refer to the following treatment methods:

1. If there is dirt or obstructions on the lens surface, it is easy to cause glare and blur when shooting. Please wipe the camera with a dust-free soft cloth before shooting, and do not wipe it with your fingers.

2. If you film the camera, it will affect the light transmission performance and focusing function of taking pictures. It is recommended to remove the lens film and try again.

3. It is necessary to keep the mobile phone stable when shooting, especially when shooting at a long distance. Please use an appropriate zoom factor. The larger the zoom factor, the smaller the viewing angle of the picture, the larger the subject, and the more sensitive it will be to environmental jitter. It is suggested to use a tripod to fix shooting or turn on the camera anti-shake function to obtain good shooting effect.

4. For close-up shooting, macro mode is recommended. For shooting in normal mode, it is recommended to keep a distance of more than 1 cm from the subject, and manually click on the screen to focus and finish shooting.

5. When taking photos or recording videos, you can click on the screen to focus. If the preview interface changes from fuzzy to clear, the focusing function of the mobile phone is normal. If the preview interface is always blurred, it may be that the camera's focusing function has failed. It is recommended to take the equipment and purchase certificate to the vivo customer service center for testing.

6. There is insufficient ambient light, which may lead to blurred imaging effect when taking photos or video recording. It is suggested to turn on the flash or use night scene mode when taking photos or video recording.

7. Some modes in the camera need a certain amount of time to complete shooting, such as night mode, which takes a long exposure time. If the mobile phone shakes or the subject moves, it will cause the photos to be blurred. Please ensure the stability of the mobile phone during shooting. It is recommended to use a tripod to fix shooting and move the mobile phone after shooting is completed.

8. Portrait mode will blur the background of the picture, so some pictures are blurred, which is actually a blur effect. If you don't need the background blur effect, you can switch to other modes to take pictures.

9. If you take pictures through the glass, it may affect the focusing function of the camera (focusing glass), thus showing a blurred effect.

1. Please check whether there is dust inside the camera. If there is, please take the product and purchase certificate to the vivo customer service center for testing.

11. if the above methods cannot be solved, please back up the important data of the mobile phone in advance and take the mobile phone to the vivo customer service center for testing and processing. (Address and contact telephone number of vivo customer service center: Go to the "vivo official website /vivo Mall" APP-- My-service outlet or click this link to enter and select the current city to get it. )

Tips: It is recommended to bring relevant purchase vouchers (such as purchase invoice/warranty card/ID card) when going, and call the staff of the service center in advance to ensure that the staff will go again during normal working hours, avoid running empty, and pay attention to safety on the way back and forth.
