The smartphone industry’s standard laboratory
for image quality

DXOMARK smartphone camera global score represents our dedicated test protocol, which we have built and continue to update based on our technical and consumer expertise. Our expertise allows us to design the lab setup and shooting plan methodology associated with our set of objective measurements and perceptual evaluation system.The camera global score is a weighted geometric average of sub-scores: Photo, Video, Zoom, Preview and Bokeh. These sub-scores are themselves the weighted average of quality attribute scores: Exposure, Color, Autofocus, Texture, Noise, Artifacts and Stabilization. The weighting system is based on DXOMARK’s experience in surveying consumers about both their smartphone camera usage and their image quality preferences, and thus are representative of the final user experience.

Our Analyzer solution allows you to reproduce all our lab tests in your own laboratory. Further, we offer a unique solution of protocol automation that allows you to automatically reproduce the totality of the shots and obtain all the measurements in the Camera v5 protocol. Our software suite automatically detects areas of interest on charts and setups, and then processes all objective and AI-based measurements. To optimize measurement repeatability, we calibrate and test each chart and every piece of equipment before shipping them from our facilities in Paris.

The necessary tools for perceptual analysis, such as our famous DXOMARK chart, are also available and we can provide training in perceptual evaluation to help you perform your own. As for testing using natural scenes, we can provide assistance in creating your own shooting plan accompanied by image quality metrics in line with our protocol.

HDR Portrait

Our HDR Portrait setup allows you to reproduce in your lab a very common backlight portrait scene — a very challenging use case for a camera module. Our setup includes a realistic human mannequin and the equipment necessary to create HDR conditions. We have developed unique AI metrics based on the large set of perceptual analyses we have performed during our 20 years of expert image quality evaluation and more than 10 years of analyzing smartphone cameras.

HDR Autofocus, Motion & Timing

The HDR Autofocus, Motion & Timing setup is a must-have for gathering numerous HDR measurements, including motion, shutter lag, and autofocus. In addition, we have recently developed a new motion blur measurement which can identify and measure the performance of deblurring software solutions.

Bokeh setup

Bokeh is an effect typically obtained with DSLR cameras having a shallow depth of field that produces a sharp plane with a blurred background. This effect is extremely complicated to reproduce via software in smartphone cameras.Our setup is composed of a mannequin to use as a sharp foreground subject, and chart containing a set of small details that challenge a smartphone’s ability distinguish between foreground and background.
