If you have a smartphone or stand-alone digital camera, odds are that DXOMARK had a role in creating it.

DXOMARK works with all the world’s top smartphone and camera makers to optimize the software, and often the hardware, that goes into each camera. During the past 10 years, our scientists and engineers, using our Analyzer testing suite, have played a key role in the rapid improvement of quality in digital imaging across the industry. Today, more than 150 camera labs worldwide use Analyzer.

The company also works with companies that produce digital imaging for drones, surveillance, automotive, and computer vision applications, all using the same rigorous scientific approach.

DXOMARK is continually expanding its capacity. In October 2019, the company added an audio lab with a dedicated team of engineers and scientists to help manufacturers reach peak performance with their devices. We are currently putting together a new display team and developing a lab with its own testing equipment and protocols that will help manufacturers optimize the performance of screens for smartphones, tablets, and computers, as well as displays in cars, trucks, and other products.

A tradition of innovation

DXOMARK started out as the Image Quality Evaluation Team at DxO Labs, a company that had a broad mission: participate in the digital revolution of the camera by finding a way to correct lens and sensor flaws through digital processing  and co-optimization. DXOMARK split off from DxO Labs in 2017, and is now a rapidly growing independent company focused on the testing and optimization of digital imaging devices in conjunction with industry leaders. More than 1 billion cameras and smartphones shipped have benefited from DXOMARK’s expertise.

Our chief executive officer, Frédéric Guichard, a recipient of the prestigious Grand Prix Académie des Sciences (2006), co-founded the company 17 years ago.

“In order to be able to create something and improve it, you have to be able to measure its performance,” Guichard said. Because the challenges of mobile photography have made camera systems incredibly complex, performance-evaluation tools and methodology are key assets in measuring the success of these systems.

Everything digital touches, it transforms,” observed Guichard about how the digital revolution completely upended the world of photography. In those early days, as he began working with the first cameras in smartphones, he realized that “the complexity of the camera hardware (lens, sensor) and its miniaturization challenges could be transferred to the processing.” Innovative algorithms embedded or in post-processing could compensate for many of the lens and sensor flaws. “This became our focus, making every camera the best it can be.

The pursuit of excellence

DXOMARK’s headquarters are in Boulogne-Billancourt, a Paris suburb. There, a growing staff of more than 100 engineers, scientists, and technicians from more than a dozen different countries work in a large office complex with 13 labs. Some employees are testing and tuning new smartphone and stand-alone cameras in coordination with camera and smartphone makers. The audio engineering team and lab focus on testing and optimizing the performance of audio components in smartphones and other devices. A new Display team is currently developing a lab and testing protocols for smartphone and tablet screens as well as screens and readouts in vehicles of all kinds.

Others work on Analyzer, the company’s complete system for testing digital imaging devices.  Analyzer consists of hardware — equipment custom built by DXOMARK to measure and test aspects of image quality and performance — and the software needed to process the results. The Analyzer team is constantly updating its testing protocols and equipment as technology and consumer habits change.

Etienne Knauer

SVP Sales & Marketing

“Everything we do is based on precise measurements,” said Etienne Knauer, SVP of DXOMARK and one of its senior scientists. “We measure, highlight problems and suggest solutions, always with the perception of the end-user in mind.” Through it all, the company has stayed rooted in the scientific method and maintained its dedication to scientific integrity.

This ethos extends to dxomark.com, where the company shares the results of its testing. The website, which gets several million page views each month, does not accept advertising of any kind, and it offers its in-depth reviews free to consumers and the media. Dxomark.com’s reviews must be scrupulously accurate and objective as scores that devices receive have tangible market consequences. Its scoring has become a field of intense competition among industry leaders.

DXOMARK’s reputation for fairness and its relentless pursuit of excellence have earned it a growing and loyal group of customers. “The more we work with clients, the more they want to work with us,” Knauer said. “We really deliver value to them.

Company History


New Display lab

We set up a lab with state-of-the-art equipment that our new Display team uses to perform display tests and evaluations.

As screens dominate people’s lives, our display team is developing the protocols for identifying and measuring the display capabilities of various types of screens. Display engineers at DXOMARK are creating benchmarks for digital displays on smartphones, tablets, computers, and on a wide range of other products, including the screens and readouts in vehicles of all sorts.


New brand identity

In face of its rapid expansion, DXOMARK has adopted a new powerful and recognizable logo—a shutter-like symbol based on DXOMARK’s original profession, that of measuring lens image quality. With its central position in our brand name, the new “O” in DXOMARK supports the simple idea that the most important of all lens quality measurements is the quantity of light transmitted. Our aim is to shed light on product quality by rigorously adhering to our values of objectivity and neutrality. The contrasting colors, arrows, and gradients in this “aperture ring” logo call to mind and amplify the idea of movement and speed, and symbolize our passion for a profession based on precise, high-quality scoring protocols. Our “O” by itself further serves to symbolize completion in our dxomark.com reviews: the appearance of a score in the center of the standalone logo authenticates and validates a review, a product, a lens, a quotation. Supported as it is by specifically-designed lettering and positioned on a forceful and stable line, our new logo’s use as part of our brand name, as a favicon, and as a standalone symbol of validity characterizes DXOMARK’s specific approach to our profession—one that is both powerful and flexible.

Introduced Audio testing

DXOMARK began operating a new smartphone audio quality benchmark, DXOMARK Audio, in October. The company gathered a team of experienced sound engineers to build a state-of-the-art audio laboratory and to develop a robust testing protocol. From an end-user perspective, engineers evaluate the playback quality of speakers as well as the recording quality of microphones in smartphones. The team studied a broad range of standards from industry associations to identify representative use cases and relevant audio quality attributes. DXOMARK.com publishes reviews resulting from these in-house tests.

Introduced Night and Wide testing

DXOMARK launched test protocols to evaluate the performance of smartphone cameras for wide-angle and night photos. Both test protocols consider various representative and challenging consumer-use cases, lighting conditions, and phone settings. Since then, DXOMARK.com regularly publishes Wide-angle and Night smart phone rear camera reviews and scores as part of its DXOMARK Camera test protocol.

Smartphone front camera testing and DXOMARK Selfie

While a third of smartphone users take selfies, most smartphone camera testing involves only the rear camera. In January 2019, DXOMARK.com launched DXOMARK Selfie, an image quality benchmark for smartphone front cameras. DXOMARK Selfie assesses such quality attributes as color sensitivity, noise, and Modulation Transfer Function (MTF), based on more than 1,500 images and more than two hours of video in various real-life and lab settings. We carefully designed the testing protocol to include common selfie use cases under various lighting conditions.


DXOMARK moves to new offices

To accommodate its planned expansion, DXOMARK moved to a new office and laboratory complex in Boulogne-Billancourt in metropolitan Paris. The complex includes five new labs, with space for more labs and for twice as many people as the previous office.

DXOMARK.com celebrates 10 years

Since its introduction in 2008, dxomark.com has established itself as the world’s top source of in-depth image quality reviews of smartphones, cameras, and lenses — trusted by industry leaders and millions of consumers. This reputation for accuracy and objectivity has led to industry leaders using DXOMARK scores during the rollout of new devices and in keynote talks. Top media outlets also rely on and quote DXOMARK scores when reporting on camera image quality.

Improvements in autofocus testing

DXOMARK’s Analyzer image quality testing system overhauled its autofocus testing module by introducing dynamic scenes and automation. Users of Analyzer 7 (and higher) can now test autofocus in a dynamic lab setup that mimics real life. A unique Automated Moving Object (AMO), introduced in this module, allows testers to save time and energy while improving the accuracy of test results.

HDR testing

This new and unique dynamic setup for testing High Dynamic Range (HDR) can automatically simulate two different lighting levels simultaneously, allowing users to assess a camera’s dynamic range capability in a controlled and repeatable setting.

HDR Module Setup


DXOMARK becomes an independent company

In September 2017, DXOMARK Image Labs (now DXOMARK) spun off from DxO Labs (which continues to design and sell photography software and camera products). As an independent company, DXOMARK’s product lines currently include our flagship Analyzer hardware and software system for image quality testing, benchmarking, and tuning; our image quality testing business; and the dxomark.com website.

Updated DXOMARK Camera protocol for smartphone rear camera testing

In 2017, DXOMARK Camera (previously called DXOMARK Smartphone) received its first major overhaul and was expanded to include more than 1,500 test images and two hours of video for each device tested. Additionally, we added tests to cover the Zoom and Bokeh (depth-of-field) features becoming common on newer smartphone models.

DXOMARK.com/cn, launch of the Chinese language website

As readers from China form a large part of our audience, we created dxomark.com/cn to give our Chinese-speaking audience better access to DXOMARK Camera reviews.

Bokeh testing setup

Bokeh is now a common feature among most flagship smartphones, and portrait shots with blurred backgrounds are very popular among smart phone users. In keeping with this trend, our R&D team developed a dedicated test setup for Bokeh.

The testing protocol includes mounting lenses on cameras and measuring the following attributes: resolution, derived from the MTF (Modulation Transfer Function) measurement; distortion and chromatic aberrations; vignetting; and light transmission (T-stop).


Introduction of DXOMARK.com alongside DXOMARK Sensor

We created dxomark.com as a free online source of in-depth camera reviews. Each DSC and DSLR camera reviewed on the website is assigned a unique DXOMARK Sensor score, determined by assessing color, noise, and the ISO sensitivity of RAW images taken with the device being tested. Analyzer, a complete system of hardware and software for testing image quality, is established as the data factory for the objective measurements that DXOMARK Sensor uses.


Analyzer updated to include noise, color, and other measurements

Analyzer undergoes a major update to include various new modules and charts related to photo quality, including a 15-patch noise chart developed to allow measurement of noise and texture. Other features in Analyzer allow the measurement of color fidelity, color sensitivity, flash, and MTF. This marks an important first step in the evolution of Analyzer as a reference for image quality testing.

Company founding and launch of Analyzer

DXOMARK began as the image quality evaluation (IQE) team of DxO Labs when it was founded in 2003. The IQE team introduced its first product that year, Analyzer (previously called DxO Analyzer) — the first comprehensive suite of hardware and software for camera testing and tuning, as well as for assessing distortion, sharpness, and vignetting, among other image quality attributes. Besides providing this solution to the industry, the team’s expertise helped photographers  get the best out of their pictures with photo-editing software and contributed to the design of image processors (ISPs) for many leading smartphone brands during the decade that followed.
