DxOMark is a website providing image quality ratings for standalone cameras, lenses, and mobile devices that include cameras. It is owned by DxOMark Image Labs.  

HOW DXOMARK EVALUATE MOBILE PHONES CAMERA ?

DxO Labs started testing smartphones and other mobile devices in 2011 and introduced DxOMark Mobile in 2012. A major update was made in September 2017, adding tests designed to stress the capabilities of current-model smartphones such as lower-light shooting, telephoto zoom, depth effect, and bokeh.
DxOMark Mobile Overall Score is the headline number reported for each tested device, and consists of: DxOMark Mobile Photo and DxOMark Mobile Video.

 VARIOUS SUB- CATEGORIES LIKE 
  • Exposure and contrast
  • Color
  • Autofocus
  • Texture
  • Noise
  • Artifacts
  • Flash
  • Zoom
  • Bokeh
EXAMPLE FOR iPhone x

“photo from – Dxomark website”
For aspects of image quality such as noise, DxOMark uses an “image quality ruler” based on previously analyzed images and determines which is best according to ruler and they also use a EXPERT PANEL for ratings.

CAN RATING RESULT BE MISLEADING ? 

1. So, first of all the score given by DXOMARK is not out of 100 they can be above 100.
2. Second, company only Headlines the overall result of the Dxomark. They did not tell us about the sub category so, that we can choose. Sure we can dig the result on Dxomark but not lot of people know about it. 
For example – Different people have different needs when it comes to a camera, looking at the individual scores that matter to you is probably more helpful and informative than comparing cameras simply based on their overall scores.

3. A firm can build their camera according to TEST done by Dxomarks. So they can perform well.
