We put the Xiaomi 14 through our rigorous SBMARK Camera test suite to measure its performance in terms of photo, video and zoom quality from an end-user perspective. This article analyzes the behavior of the device in a series of tests and several common use cases and aims to highlight the most important results of our tests with an excerpt of the acquired data.

Przed
- Problemy z dopasowaniem ekspozycji często widoczne w filmach w większości testowanych warunków
- Niski kontrast na twarzach w jasnym świetle i przy podświetleniu
- W trybie wideo szumy są zauważalne przy słabym oświetleniu

Xiaomi 14 wykazał znaczną poprawę jakości obrazu, szczególnie w przypadku filmów, w porównaniu do swojego poprzednika, Xiaomi 13, częściowo dzięki ulepszeniom sprzętowym, takim jak większy czujnik i większa apertura.
The device received high marks for its texture-noise trade-off, with images having a high level of detail and low noise in most conditions tested. The texture-noise compromise is one of the best we’ve seen for this price range, surpassing its direct competitors. The Xiaomi’s neutral white balance in most situations means that the device is particularly suitable for taking landscape photos. However, when taking photos of people outdoors, the images often showed mixed results, with low contrast on faces and sometimes overexposure of the subject. This would have affected the color rendering, which was at times imprecise and desaturated. The device showed some irregularities in autofocus. When photographing action scenes, the images would contain some artifacts, such as ghosting, giving the photo an unnatural photographic appearance.
Wydajność zoomu Xiaomi 14 była dobra w swoim segmencie, wspomagana przez czujnik 50 MP modułu tele, który zapewniał obrazy o bogatej teksturze, szczególnie przy korzystaniu z zoomu dalekiego zasięgu.
The video experience of the Xiaomi 14 has been much improved compared to previous generations. The target exposure was accurate and the videos contained a wide dynamic range both indoors and outdoors. Similar to photos, videos contained plenty of detail and texture, while white balance remained fairly neutral. Video autofocus was a little unstable when panning a scene, but overall autofocus was much better than on the Xiaomi 13. Furthermore, videos also showed some exposure instabilities in several tested conditions.
Wydajność wideo Xiaomi 14 przy słabym oświetleniu była nieco gorsza niż u konkurentów z tego samego segmentu cenowego, głównie z powodu bardziej zauważalnych szumów i niedokładnego renderowania odcieni skóry.
Podsumowanie testu
O testach kamer SBMARK: SBMARK camera evaluations take place in laboratories and real-world situations using a wide variety of subjects. Scores are based on objective tests whose results are calculated directly by the measurement software in our laboratory setups, and on perceptual tests where a sophisticated set of metrics allows a panel of imaging experts to compare aspects of image quality images that require human judgment. Testing a smartphone involves a team of engineers and technicians for about a week. Photo, zoom and video quality are evaluated separately and then combined into an overall score for comparing cameras on different devices. For more information on the SBMARK camera protocol, click here. More details on smartphone camera scores can be found here. The following section compiles key elements of SBMARK’s comprehensive testing and analysis. Full performance evaluations are available upon request.

O testach fotograficznych aparatu SBMARK
For scoring and analysis, SBMARK engineers capture and evaluate more than 2,600 test images in both controlled laboratory environments and natural outdoor, indoor, and low-light scenes, using the camera’s default settings. The photography protocol is designed to take into account key use cases and is based on typical shooting scenarios, such as portrait, family and landscape photography. Evaluation is performed by visually examining images Cons a natural scene reference and performing objective measurements on laboratory-captured graph images under varying lighting conditions from 1 to 1,000+ lux and color temperatures from 2,300K to 6,500K.

Photography tests analyze image quality attributes such as exposure, color, texture and noise under various lighting conditions. Autofocus performance and the presence of artifacts are also evaluated on all images captured under controlled laboratory conditions and in real-life images. All of these attributes have a significant impact on the final quality of images captured with the tested device and can help understand the camera’s key strengths and weaknesses.
Xiaomi 14 – Accurate target exposure, neutral white balance. The level of detail is high and noise is well controlled.

WYKRES SBMARK (DMC) Retencja szczegółów w porównaniu z poziomami luksów w warunkach statywu i trzymania w ręku
This graph shows the evolution of the DMC detail retention score with lux level, for two retention conditions. The DMC Detail Retention Score is derived from an AI-based metric trained to evaluate the performance of texture and detail on a selection of crops from our SBMARK chart.
Ewolucja szumu wizualnego wraz z poziomami oświetlenia w warunkach ręcznych
This graph shows the evolution of the visual noise metric with lux level in handheld conditions. The visual noise metric is the average of the visual noise measurement across all areas of the Dead Leaves graph in the AFHDR configuration. SBMARK visual noise measurement is derived from the ISO15739 standard.
