How do you adjust the focus of the Xiaomi Mi 8 and does the Xiaomi Mi 8 have laser focus?

A LETV mobile phone I used before also appeared in the situation that the landlord said,Every time you need to take a picture or scan the code,You need to wait for half a day,Extremely unhappy,Sometimes it's good to shoot hard,But not every time it's bright。 Later, it was changed to my husband, and he couldn't stand it for a while, because the mobile phone was bought by an acquaintance, and it was troublesome to find customer service for maintenance, and then ** bought a mobile phone camera of the same style, and replaced it with his own tinkering, and after replacing it, the world is really clear. Therefore, this problem is most likely a problem with the mobile phone camera, and it has nothing to do with memory, software optimization, etc.

If the hands-on ability is strong, the landlord can also buy the mobile phone camera online to replace it himself, if the hands-on ability is limited, or send the customer service for maintenance.

0 small aperture does not have the depth of field effect, the mobile phone lens cannot change the aperture, and it will be clear if you take it farther.

I'm going to throw bricks and lead the landlord to popularize science.

This is the effect of a wide aperture depth of field, and it has nothing to do with what the focus is, you can clearly shoot an object, and the evidence is in focus. As for the other one, it doesn't close because your aperture is wide open (the aperture of the phone can't be changed, only the maximum), and the two objects are not on the same focal plane.

Whether it is a mobile phone lens or a camera lens, once in focus, all objects within the focusing distance are clear, just like taking your mobile phone lens as the center point, all objects on an arc-shaped surface within the lens visual range can be in focus, and if it is too close or too far, it is a false focus, but this is only relative, not absolute. If you are about close to the focal distance, the smaller the error of this value, a little staggered distance will be out of focus, on the contrary, if you take it far away, the error of this value is very large, and the distance is very far can be basically focused, so I suggest you take a little farther to try.

Whether it is false focus or not, it is also related to the size of the aperture, here to mention the depth of field, simply put, the larger the aperture, the shallower the depth of field, only the distance of the focus is clear, and the outside of the focus is blurred; Conversely, if the aperture is very small under the same condition, the depth of field is large, and it is clear for a distance outside the focus. Because the aperture of the mobile phone cannot be changed, it can only be turned on to the maximum by default. Like the ** on the main floor of your building, if the SLR is open above or so, the depth of field is very shallow, that is, you can only describe one clearly, and any of you open below F5 through the depth of field is very large, and both are clear.

However, the phone can't change the aperture, and the maximum aperture is turned on by default, so the depth of field for close-up shots is relatively shallow. This has nothing to do with the dual lenses,The "depth of field" of the mobile phone is made of digital post-production,

Method steps.

1 6 Step by Step Reading.

What is Macro.

To put it simply, what you want to shoot is clear and vivid, and what you want to shoot is hazy around it, and the technical term is also called depth of field.

The Xiaomi Mi 8 mobile phone's automatic shooting can actually shoot macro effects, but it must be in good focus, and don't shake, don't shake. It is also necessary to have plenty of light, and automatic shooting can also be used to shoot macro effects.

Of course, the macro shot with auto shooting may not be particularly noticeable. This is where manual shooting comes in.

1. Turn on the Xiaomi Mi 8 camera and slide to Manual.

2. There are five values in it: white balance, focus, shutter time, sensitivity, and lens.

3. If we want to shoot something close, change the lens to "wide angle" first, otherwise the "telephoto" lens will be too blurry.

Next, set the White Balance:

1. The setting of "White Balance" can choose the appropriate "White Balance" according to the lighting situation of the shooting object.

1. In the case of general macro shooting, we can set the focus and shutter time to automatic.

Sensitivity: 1. The minimum sensitivity of Xiaomi Mi 8 is 100, and the maximum value is 3200

2. The smaller the sensitivity, the smaller the impurities in the captured picture and the cleaner the picture.

3. Therefore, if you shoot macro, the sensitivity is generally the smallest.

Normally, you can just click on our center after we turn on our camera, so you can do this kind of focusing. Below is an extended section on focusing.

Conventional cameras use a method similar to visual ranging to achieve autofocus, the camera emits a kind of infrared (or other rays), determines the distance of the subject according to the reflection of the subject, and then adjusts the lens combination according to the measured results to achieve autofocus. This method of autofocus – direct, fast, easy to implement, and low cost – but sometimes it can be wrong (autofocus is not possible when there is something else between the camera and the subject, such as glass, or in low light), and is not very accurate, and is generally not used in today's high-end cameras. Because the camera actively emits rays, it is called active, and because it is actually only a distance measurement, and does not judge whether it is correctly focused through the actual imaging of the lens, it is also called non-TTL type.

Compared with active autofocus, this focusing method later developed passive autofocus, that is, judging whether it is correctly focused according to the actual imaging of the lens, and the basis for judging is generally contrast detection, and the specific principle is quite complex. Because this method is achieved by lens imaging, it is called TTL autofocus. Because this autofocus method is based on lens imaging, it has high focusing accuracy and a low error rate, but it is technically complex, slower (except for advanced autofocus lenses with ultrasonic motors), and high cost.

Click on the place you want to shoot, generally it will automatically focus, I hope it helps you, thank you!

Laser focus makes it easy to focus even in dark environments, while enabling face-tracking assisted focusing, and helps optimize white balance tuning for clearer photos, which is currently not available on the Mi 8, which is standard on the Mi 9 series.

1.Change the photo mode to automatic mode to try;

2.Reset camera parameters attempt: Camera - Settings (gear icon) - Restore default settings (Reset);

3.If it does not work, it is recommended to update the system version of the mobile phone (Note: please back up the data in the device before upgrading);

4.If you still can't focus, please back up the data in your phone and try to restore the machine to factory settings.

Mine is also very slow to focus. I don't know how to fix it.

What is IR focus used for? Xiaomi Mi 8 only has an infrared face recognition camera, this camera is used to identify face unlocking, focusing is a function that both ordinary cameras and AI cameras have, Xiaomi Mi 8 does not have an infrared emission sensor and cannot use the remote control.

Generally speaking, the phone can autofocus, and you can try to take a photo after restarting the phone.

Xiaomi Mi 10 beats the moon to adjust the parameters:

1.Turn on the Xiaomi Mi 10 camera function to enter the shooting page;

2.Turn on the camera's AI mode and point the lens at the moon;

3.Then zoom, use the quadruple zoom, and then the moon mode will automatically turn on, keep the camera steady, and then shoot.

Xiaomi Mi 10 mobile phone shooting moon parameters, white balance 5000, this can be adjusted according to the effect of your own mobile phone, or directly choose a small sun, focus 100, shutter time 1 1000 seconds, sensitivity 100, lens selection wide angle, and then enlarge the picture against the moon, zoom to the maximum, generally the largest zoom! Note! Don't shake your hands, take a few more photos and choose one that is worthwhile!

If you want to shoot the director, you can shoot directly with the camera that comes with your phone.

Xiaomi 10 Beat Moon Quenching and Tempering His Injury Parameters, it is automatically adjusted, as long as you follow its focus.

The parameters of the moon on the Xiaomi Mi 10 mobile phone can be adjusted in the camera.

Huawei P20 Pro rear camera 40 million pixels (color, F aperture) 20 million pixels (black and white, f aperture) + 8 million pixels (telephoto, f aperture), Leica lens, support autofocus (laser focus, depth focus, phase focus, contrast focus), support Huawei AI image stabilization; The front camera has 24 million pixels, f aperture, and supports fixed focal length.

As the most basic function of smart phones, the camera function can be a project that major manufacturers are struggling to compete in recent years, especially for flagship mobile phones, whether it is good to take pictures or not, to a large extent, will be proportional to its sales. If you say that the ability to take pictures is insufficient, then it is likely to fall behind competing products at the same price, and even be pressed by competing products to "beat".

As for the camera function of domestic smartphones? I think at this stage, Huawei should have the most right to speak. Huawei released the Huawei P20 P20 Pro at the beginning of the year, of which the P20 Pro also pioneered a triple camera design, and the rear used a 40 million + 20 million + 8 million pixel Leica triple lens.

It can achieve 3x optical zoom and 5x triple camera zoom. At the same time, the HUAWEI P20 Pro is equipped with a 40-megapixel main camera, which is currently the only smartphone product to reach a 1-inch image sensor, and its shooting effect is comparable to that of a professional-grade digital camera.

Of course, in addition to Huawei, Xiaomi is actually catching up. Because the previous flagship machine's ability to take pictures was somewhat unsatisfactory, it was also a little embarrassing compared to competing products. Since the Xiaomi Mi MIX 2S, Xiaomi has been determined to improve its camera R&D and capabilities, and at the same time, they have set up a separate camera department to strengthen camera R&D, which is much more important than other projects.

From the point of view of results, in DXOMARK, Xiaomi Mi 8's comprehensive results also surpassed iPhone X, and Xiaomi's strength is also worthy of recognition.
