DxOMark only publishes tests of commercial samples, and sometimes we get up very early to do so!
The DxOMark testing lab is setup to simulate a variety of lighting conditions that are representative of real life conditions.
Combined with tests run under controlled lighting conditions, DxOMark engineers scrutinize mobile phone performance under the most challenging home, office, and outdoor photographic conditions.
We do extensive testing outdoors to see how well mobile cameras operate under natural lighting conditions.
DxOMark engineers perform perceptual analysis of natural-scene photos on calibrated screens in a controlled environment.
DxOMark Mobile protocols follow international standards (ISO, I3A) for image quality evaluation.
DxOMark Mobile reports are powered by DxO Analyzer, the leading software solution for measuring the image quality of digital cameras. (DxO Analyzer is used by all major camera and mobile manufacturers.)
Color measurement: After photographing a multi-colored target, DxO Analyzer determines how accurately the sensor reproduces colors.
Exposure and contrast measurements: DxOMark analysis under challenging conditions highlights performance differences between mobile camera products.
Texture measurement: The innovative DxO Dead Leaves Chart test helps DxOMark determine how well the camera preserves low-contrast details.
Artifact measurements detect distortion, chromatic aberrations, and vignetting. DxOMark imaging experts follow rigorous protocols to ensure repeatable results.
Flash measurements: DxOMark engineers measure how well the flash fills the entire image, its repeatability, and how well colors are preserved.
Autofocus measurement: This test uses a Spatial Frequency Response chart to measure how reliably the automatically adjusts to the sharpest focus.
Video stabilization measurement uses a computer-controlled hexapod system that simulates natural hand-shaking movement.
Video artifact measurements: DxOMark engineers examine dedicated video scenes to look for blocking artifacts and for artifacts such as jello effect due to electronic rolling shutter.
To test each mobile product with DxOMark Mobile protocol, DxOMark engineers shoot and analyze more than 400 pictures and 20 videos.
