How to turn on Xiaomi camera age determination

Many Xiaomi, Redmi and Poco smartphone users, when they hear about the possibility of changing the appearance in the photo, wonder how the camera can turn on the age determination, often referring to the rejuvenation function or, conversely, the addition of wrinkles, which is available in the standard application. However, it is important to immediately clarify the technical point: the built-in algorithm does not scan biometric data for exact age, but uses stylized beauty filters.

The regular camera app in the MIUI or HyperOS shell is equipped with a powerful AI module that analyzes the face in real time. It is this module that is responsible for smoothing the skin, changing the shape of the face and adding effects that visually change the perception of the person's age in the picture. To activate these features, you do not need to look for hidden engineering menus, just adjust the shooting parameters correctly.

In this article, we will take a closer look at where beauty sliders are, how portrait modes work, and what third-party solutions may be needed if standard functionality is not enough. You will learn how to manage the degree of retouching so that the photos look natural, not like a plastic doll.

The principle of operation of beautify algorithms in MIUI

Often referred to as “age determination,” the feature is technically a complex of Beautify AI algorithms: it recognizes key points on the face: eyes, nose, lips, facial oval and skin texture. Based on this map, the software layers a digital retouch layer. The higher you put the slider values, the more distorted the real picture is, which visually rejuvenates the subject.

In newer versions of Xiaomi firmware, algorithms have become more aggressive by default, the camera itself tries to guess what to do with the face to make it conform to beauty standards. But automation often overdoes it, making the skin unnaturally smooth, which is why manual control of parameters remains the preferred option for those who want to maintain their individuality.

Note that processing occurs at the time of shooting (for JPEG) or when saving (for RAW with application).This means that the source file already contains the applied effects. Neural networks operate locally on the smartphone processor using the power of the NPU (neural processor), which allows you to see the result in the viewfinder without delay.

⚠️ Warning: Excessive use of anti-aliasing filters can lead to loss of skin texture and blurring of small details such as eyelashes or eyebrows, making the face look unnatural.

💡

For the most realistic effect, try not to raise the smoothing slider above 40-50%. The natural texture of the skin is more important than the perfect smoothness.

Step-by-step instructions for activating filters

To access the look and feel control, you need to go to a special camera mode. The standard interface often hides advanced settings to avoid overloading the user. Follow the algorithm to find the right tools.

Open the Camera app first, and select Portrait or Photo mode from the bottom menu. In some versions, beauty settings are available immediately, in others, you need to switch. Click on the icon with three lines or a magic wand at the top of the screen.

Then you pick a face icon or a "Bouty" sign, and you'll see a slider panel that you can adjust not only the overall beauty, but also the specific parameters: eye size, nose shape, lip color and, importantly for our topic, the degree of smoothing of the skin, which directly affects visual age.

Experiment with each slider separately, for example, adding "glare" to your eyes or changing the shape of your jaw can dramatically change your face perception, and don't be afraid to try extremes to understand the range of capabilities of your device.

Setting up the parameters of the face and body

There are many subtle adjustments that are hidden inside the beauty menu that allow you to work through the image in detail, and the Face section allows you to change the geometry: narrow your chin, enlarge your eyes, raise your eyebrows, and these changes are often associated with signs of youth, so using them extensively creates a rejuvenating effect.

The Skin section is worth noting, and it's got tools to fight wrinkles, pigmentation and uneven tone. The Xiaomi AI algorithm automatically detects and masks problem areas, and you can manually enhance the bleaching effect, or you can add blush, which is also juvenile.

And the body parameters, if you're shooting full-length, change the proportions of the figure, and although this doesn't affect the face, the overall visual image becomes more photoshopped and more social media-driven.

Use of Portrait and Video Modes

Portrait mode is the primary tool for people to take art, where the bokeh blurring effect is combined with beautify algorithms, and it's in this mode that facial detection works most accurately, allowing the most complex effects of changing appearance to be applied.

When you're shooting video, it's also available, but it's limited to not overloading the processor. You can turn on the beauty effect before you start recording, and it's going to be applied in real time to every frame. It's useful for creating content in TikTok or Instagram Reels right on your phone.

Noise suppression conflicts with facial details, which can lead to a soapy image, and in such situations, it is better to reduce the intensity of the filters.

💡

Portrait mode provides the best quality of face processing through the use of a telephoto lens and a deep scene map.

Third-party editing applications

If you don't have enough of Xiaomi's camera, the market offers a lot of third-party solutions, like Snow, B612 or FaceApp, which use more advanced neural networks to change age, which can not just smooth out the skin, but actually "age" the face by adding gray hair and deep wrinkles, or vice versa, make an adult child.

These applications often require permission to access the camera and gallery, and they work as a separate layer on top of a standard camera, or as editors for finished photos, and their algorithms are trained on millions of images, producing more impressive and sometimes frighteningly realistic results.

Using third-party software allows you to access features that the smartphone manufacturer has not built into the standard firmware, such as changing facial expressions or adding aging elements that are not available in the MIUI menu.

Comparison of processing capabilities

To better understand the difference between standard tools and advanced methods, it is worth considering their comparative characteristics. The table below will help determine the choice of editing method.

As you can see from the table, for fast daily shooting, the capabilities of the native camera are quite enough, but to create specific content that requires a radical change in age, it is better to use specialized software.

Typical problems and their solution

Users often experience a situation where the camera does not recognize the face or applies filters in jerks, this can be due to a lack of RAM or an outdated version of the camera drivers. First of all, try to clear the cache of the Camera application through the settings of the smartphone.

Another common problem is unnatural skin color after applying filters, the face may become too orange or white, in which case it is recommended to reset the beauty settings to factory values and start adjusting again, moving the sliders minimally.

⚠️ Warning: If the camera stopped focusing on the face after the system update, check if Macro or Night Mode is turned on, which may conflict with portrait shooting algorithms.

Also, keep in mind that protective glass or dirt on the lens can impair facial contours recognition.

💡

If the camera app is not running smoothly, try installing an older stable version from a trusted source or upgrading to the latest available MIUI beta.
