DxOMark is an organization that specializes in DxOMark is an organization dedicated to the evaluation of camera products, and its evaluation criteria is to measure and rank the image quality of cameras and lenses according to industry standards, which is why the platform has become one of the world's most famous and professional camera testing organizations.

DxOMark was founded in 2003. They have their own tester and calculation formula, which can process the RAW format files generated by the camera and produce quite objective and informative data. With the public test descriptions, the generated data can be used as a parameter table to illustrate the performance indicators of the machine.

In the test chamber coated with matte material, the temperature was controlled at 21-25 degrees and the humidity was between 30-70%. In addition to the evaluation of the camera, also began to score the phone.

DxOMark scored each phone as above, divided into "exposure and contrast, color, focus, detail texture, noise control, Artifacts, flash effect" 7 items. Among them, Artifacts is caused by the sensor, lens, electronic noise, algorithms together with the deterioration of the picture quality, including the purple edge, jaggedness, noise, sharpening vignetting (sharpening too much caused by the edge of the white edge), moiré and other phenomena.
