AI camera in Xiaomi Redmi Note 9 Pro: a full analysis of technology

Smartphones are no longer just calling devices, but powerful content creation tools. Owners of the popular Xiaomi Redmi Note 9 Pro often wonder what exactly lies behind the mysterious acronym AI in the camera app. This technology has become the standard in mobile photography, but not all users understand its real potential and impact on the final result.

The AI algorithms in this device run in the background, analyzing each frame in real time, and are able to recognize dozens of different scenes, from flower buds to cityscapes, automatically adjusting exposure and saturation settings, and understanding how it works will allow you to take professional-quality shots using only the built-in capabilities of the gadget.

In this article, we will look at how neural networks work, look at specific examples of image enhancements, and see where it’s smarter to turn off the function. You’ll learn how the machine learning algorithm in Redmi Note 9 Pro analyzes up to 200 different scenarios to achieve the best possible result.

The principle of artificial intelligence in the photomodule

The AI Camera feature in the Xiaomi Redmi Note 9 Pro is a software package that uses the processing power of the processor to process the image. Unlike conventional filters, which are imposed after the fact, the neural network analyzes the scene before the shutter is released, it determines objects, their location, lighting and even emotional coloring of the frame to apply the most appropriate parameters of shooting.

The basis of this technology is a database of millions of photos that the algorithm was trained on, and when you point the lens at the object, the system compares the picture to the patterns it knows, and if you recognize, for example, a sunset, the camera automatically increases the saturation of red and orange tones, and also aligns the dynamic range so that the sky is not too bright and the shadows do not fall into blackness.

Importantly, processing happens locally on the device, without the need for an internet connection. This provides an instant interface response. The user sees the result immediately in the viewfinder, allowing the composition to be adjusted on the fly. The system is constantly learning, receiving updates through the system patches MIUI, which gradually improves the quality of recognition of complex scenes.

• 📸 Automatic determination of scene type (food, nature, documents, portrait).
• 🎨 Dynamic adjustment of color palette and contrast.
• 🚀 Accelerating focus on recognized objects.
• 🌙 Optimization of shooting parameters in insufficient lighting.

Consider that active AI consumes additional CPU resources, as you might see in high-resolution video or serial shooting, but for most use cases, the performance difference is invisible to the average user, but the visual gain is obvious.

Scene recognition and automatic optimization

One of the key features of the Redmi Note 9 Pro is the camera's ability to identify more than 200 different shooting scenarios, and when the camera is getting stuck at an object, an icon in the top corner of the viewfinder shows the name of the scene it recognizes, which can be "Food," "Sky," "Green," "Documents," or "Night Shooting," each of which has a unique processing profile.

For example, when you're shooting food, the algorithm increases the saturation of warm colors, making the dish more appetizing in appearance. If you're photographing documents, the system enhances the contrast of text and aligns perspective, removing the distortion of angles. In "Green" mode, the emphasis shifts to the shades of leaves and grass, making them more juicy and alive, which is especially true for parks and forests.

⚠️ Attention: In some cases, automatic improvement can lead to unnatural colors, such as the grass can become unnaturally bright salad, and the skin of a person can become orange. AI.

The accuracy of recognition depends on the lighting conditions and the clarity of the contours of the object. In complex conditions, for example, in mixed artificial and natural light, the algorithm can fluctuate between several scenarios, in which case it chooses the most likely option or averages the settings so as not to spoil the frame.

For users who value control, there's a manual adjustment to the settings that you've set, and once the camera has identified the scene, you can click on the setting icon and change the degree of effect, and you can balance realism with artistic expression.

• 🍕 Food: Enhancing warm tones and texture.
• 🌳 Plants: Saturation of the Green Spectrum.
• 📄 Documents: Increased text sharpness and contrast.
• 🌅 Sunset: Balance of the brightness of the sky and details in the shadows.

If the camera misidentified the scene, click on the AI icon in the viewfinder to manually select the desired mode or turn off automatic correction.

Portrait mode and improvement of faces

The Xiaomi Redmi Note 9 Pro has an advanced segmentation algorithm that precisely separates a person from the background, allowing for a bokeh effect without the use of additional telephoto lenses, relying solely on computation.

It also analyzes facial parameters, such as gender, age, and even the presence of accessories such as glasses or a hat, and uses beautification algorithms to gently smooth out skin, remove temporary defects, emphasize eyes, and even add makeup, and is controlled by a slider to achieve both a natural and a highly retouched appearance.

An important feature is group portrait recognition, where the camera tries to illuminate all faces evenly, even when they are in the shade or in bright light. The HDR algorithm in portrait mode works especially aggressively, keeping details in light and dark areas at the same time.

It is worth remembering that excessive use of beauty filters can lead to loss of personality and "plastic" effect, it is recommended to set the correction values at minimum or average levels to preserve naturalness.

Night photography and lighting

Night photography is the area where computational photography is most vivid. In low light conditions, the Redmi Note 9 Pro cannot physically capture a quality frame in a split second. AI-algorithmically.

When you activate night mode, the camera takes a series of images with different exposures in a short period of time, and artificial intelligence analyzes each frame, selecting the clearest areas, and combines them into one final image, which allows you to significantly reduce the level of digital noise and pull details out of deep shadows.

The algorithm also identifies artificial light sources, such as neon signs or lampposts, and prevents them from overlighting, and the colors become more saturated and clear at night, and the sky takes on a deep blue hue instead of the gray porridge typical of normal shooting.

⚠️ Note: When using night mode, you must keep the phone still for a while. 2-4 Any shaking of the hands will cause the image to be lubricated, because the algorithm will not be able to correctly match the frames.

And AI also helps in counterlight situations, like when you're shooting a person against a bright window or sunset, and it recognizes the silhouette and automatically turns on the face light without overexposing the background, and it creates a harmonious balance between the object and the environment.

💡

Night mode with AI is not just a lightening picture, but a complex process of synthesis of several frames to reduce noise and expand the dynamic range.

How to turn on, configure or disable the AI camera

Managing the AI feature in the Xiaomi Redmi Note 9 Pro is as simple as possible for the user, it is activated by default, and the "AI" icon burns at the top of the viewfinder screen. However, in certain situations, you need to configure or completely disable this option.

To access the settings, open the Camera app. In the top panel, you'll see an "AI" icon. Pressing it switches modes: "On," "Off," or select specific scenes. For a deeper setup, go to the menu by clicking on the three bars in the top right corner, and select "Settings."

You can find the camera settings section, "AI Improvement," or similar, where you can detail the behavior of the system, and there are switches available for specific functions, such as scene recognition, portrait enhancement, or text optimization, and disabling these features can be useful if you plan to further professionally process photos in third-party editors.

• 🔽 Press the badge. AI at the top of the screen for quick switching.
• ⚙️ Go to the menu. → Settings for detailed management.
• 📉 Turn off Improvement. AI" obtain RAW-file-processing.
• 🔄 Reset the camera settings if there are malfunctions in the algorithms.

If you notice the camera is slow or making strange color distortions, try clearing the camera app cache or resetting it to factory settings.This often helps to fix software bugs accumulated during the updates process.

Comparison of results: with and without AI

To understand the real value of technology, it's worth making a direct comparison of images taken with the intelligence on and off. The difference is often enormous, especially in difficult light conditions. Without AI, photography looks "raw": colors fade, shadows deep and black, and lights can be ejected.

With AI enabled, the image becomes more "journalized." Colors become more ringing, contrast becomes more expressive, and detail in the shadows allows you to see what (with the naked eye) was barely noticeable. However, as mentioned earlier, sometimes this processing can be redundant, making the picture unnatural.

For post-processing enthusiasts, the AI-free mode is preferable, as it stores more of the original information in the file without “baking” contrast and saturation forever. For the average user who wants to immediately get a ready frame for social networks, the AI mode is the only option.

The table below shows the key differences that will help you decide on the choice of mode for a particular situation:
