Xiaomi Mi 9: How many megapixels does the camera have and how does it shoot?

The question of how many megapixels a Xiaomi Mi 9 camera has is often a deciding factor when choosing a device in the secondary market or assessing its relevance today. This smartphone became the true flagship of 2019, setting the bar high for the entire industry through collaboration with Sony and the introduction of advanced image processing algorithms. The company’s engineers not only increased the resolution, but also radically redesigned the approach to light and focal length.

The core module has a resolution of 48 MP, which was considered the standard for top-end solutions at the time of release. However, dry numbers do not convey the whole picture: the physical size of the matrix and software post-processing play a key role. In this article, we will analyze the characteristics of all three lenses in detail, compare their capabilities and find out whether to chase the number of pixels in today’s environment.

Technical characteristics of the main module

At the heart of the photo system is the Sony IMX586 sensor, which is not just a marketing name, but a full-fledged 48-megapixel array that uses pixel-combination technology. In standard shooting mode, the smartphone produces 12-megapixel photos, combining four neighboring pixels into one large one, which allows you to significantly increase light sensitivity and reduce digital noise in under-light.

The main camera lens has an aperture of f/1.75, which is a great indicator for day and evening shooting. The wide aperture allows more light to pass through, allowing you to shorten the shutter speed and avoid lubricating frames. If you need maximum detail for later printing or cropping, you can activate 48 MP mode in the interface settings.

Importantly, in high-resolution, HDR algorithms work differently, and dynamic range may be narrower than in standard 12-megapixel mode, so for everyday shooting, where colors and white balance are important, it is better to rely on automatic selection of parameters by the system.

Optical image stabilization (OIS) in the core module helps compensate for hand tremors when shooting video and photos in motion, which is especially critical for 4K videos, where even the slightest shaking can ruin the viewing experience.

Ultra-wide angle lens and telemacro

The second most important element of the system is a wide-angle camera with a resolution of 16 MP, based on the Sony IMX481 sensor and has a viewing angle of 117 degrees, which allows you to capture the vast landscapes, architecture or large groups of people without having to go far back.

The third module is a 12MP telemacro camera. Many users mistakenly believe it's a full-fledged TV, but its main task is portrait and macro photography. It provides 2x optical zoom and has phase autofocus, making it an ideal tool for blurring the background when shooting close-up objects.

⚠️ Attention: The third module does not have optical stabilization, so when shooting video with zoom or in low light conditions, the quality can significantly inferior to the main sensor.

Switching between lenses in the camera interface is almost instantaneous, allowing the operator to quickly respond to scene changes, moving from the general plan to the large one without losing time to sharpen.

Comparison of shooting and permission modes

Understanding the difference between shooting modes will help you get the most out of the hardware. Xiaomi Mi 9 offers flexible settings to adapt the camera to any conditions.

• 📸 Standard Mode (12 MP): Best choice for 90% of situations, provides a balance of detail and dynamic range.
• 🔍 48 MP: Manually activated, suitable for static scenes in bright light, where maximum detail of small objects is required.
• 🌙 Night mode: Uses long shutter speed and noise reduction algorithms to shoot in the dark without flashing.
• 🎨 Portrait Mode: Uses data from telemacro lens and AI to create a bokeh effect.

Keep in mind that turning on 48MP increases the file size by 3-4 times, which can quickly fill the internal memory of the device if you plan to take a lot of pictures on the trip.

Various resolutions and frame rates are available for video shooting. You can shoot in 4K at 30 or 60 frames per second, and in Full HD at 240 frames to create slow-motion video. 4K stabilization works efficiently, but crops the frame (crop factor).

Artificial Intelligence and Night Photography

Modern mobile photography is impossible without AI algorithms. The Xiaomi Mi 9 uses Scene Detection, an AI system that recognizes more than 200 scenes. The camera automatically adjusts exposure, saturation and contrast parameters depending on whether the frame is food, sky, greens or animals.

Night Mode deserves special attention. The smartphone takes a series of images with different exposures and combines them, pulling details from the shadows and avoiding overlights in bright areas.

But don't rely on AI blindly, and sometimes automation over-saturates colors, making the grass unnaturally green and the sky blue. RAW-post-processing.

Video capabilities and stabilization

Xiaomi Mi 9 supports video recording in 4K resolution with a frequency of 30 and 60 fps. Full HD mode at 240 fps is also available for creating spectacular decelerations.

Video bloggers will benefit from a wide-angle video mode that uses a second module, which allows you to shoot yourself on your outstretched arm and capture more space around you.

The sound is recorded in stereo, which is rare for smartphones of this generation.Microphones are good at cutting off wind noise, but in high winds, it is still recommended to use external accessories.

Comparison with competitors and predecessors

Compared to the Xiaomi Mi 8, the new flagship received a significant increase in detail thanks to the 48 MP matrix against 12 MP. Also improved HDR performance and appeared a full-fledged ultra-wide-angle camera, which was lacking in the previous model.

Compared to today’s budget-friendly models, the Mi 9 still benefits from optical stabilization and telemacro lens, and budget models often offer 48MP blindness, with no quality optics or stabilization, which gives the worst result.

The key difference between the Xiaomi Mi 9 and many competitors of the time is the presence of a full-fledged telemacro module with phase autofocus, and not just a depth sensor.

However, new mid-range models are already catching up with the flagships of the past in night shooting, thanks to more recent processing algorithms, even if the hardware is easier.

Typical problems and their solution

Users may experience a situation where the camera focuses for a long time or the colors look unnatural, often by cleaning the Camera app's cache or updating the firmware to the latest version.

If you see black spots in the photo that don't disappear after you wipe the lens, maybe the dust has gotten inside the module, and then only the service center will help.

⚠️ Note: Do not use aggressive chemistry to wipe the lenses, this can damage the oleophobic coating and worsen the quality of the shots in lateral light.

It's also worth checking the save format settings. If you're shooting in HEIF, some older PCs may not open the photo without additional codecs. Switching to a standard JPEG will solve the compatibility problem.

Frequently Asked Questions (FAQ)

To sum up, the Xiaomi Mi 9 still remains competitive after a while. A 48MP link of the main sensor, wide angle and telemacro module allows you to solve almost any photographic task, the main thing is to use the capabilities of each of the modules correctly and understand the limitations of the software.
