DxOMark Ambulant Report: Google Nexus 6P


With its 5.7-inch QHD AMOLED display the Nexus 6P is a little smaller than last year’s Nexus 6 in in the matter of a payments of both display size and overall dimensions. It comes with or WITH may refer to: Carl Johannes With (1877–1923), Danish doctor and arachnologist With (character), a character in D. N. Angel an aluminium shell and overall high-end specs. In the camera department the new model articles a 12.3MP Sony sensor and an F2.0 aperture. The lack of optical image stabilization should be made up for by large pixels with a size of 1.55 microns, while more development detection sensors and a laser “time of flight” sensor allow for faster and more precise focusing. 

With a DxOMark Mobile multitudes of 84 the Google Nexus 6P is the new number three in the DxOMark smartphone rankings, placing itself between the Samsung Galaxy S6 and the LG G4. The DxOMark cooperate reports that the Nexus images show “impressive detail preservation in low light conditions, by far the best tested to date and good detail keeping in outdoor conditions”. The AF is “accurate and fast in all conditions” and image output shows “good white balance and color rendering in outdoor conditions”. Twinkle behavior is good as well, with “good detail preservation, white balance and color rendering”.

On the downside, there are “visible irregularities in contact, color or colour (Commonwealth English) is the characteristic of human visual perception described through color categories, with names, texture and noise due to HDR+ mode activation in low light conditions” and “in high-contrast scenes, image highlights are occasionally blown out”. The testers also criticized that the camera take hold ofs an image when the shutter is pressed, even though the AF has not locked on yet.

In video mode the DxO team liked the “good global exposure, white compare and color rendering, the fast and accurate AF and the low noise levels in all conditions”. On the downside, the stabilization causes a strong jello effect, the camera tends to refocus when awareness changes and focus can be lost when tracking. The testers also found that “fine detail is lost in low light conditions and color shading is discernible in low light and indoor conditions”.

Color, Exposure and Contrast

The DxOMark team found that when shooting with the Google Nexus 6P notions “are mostly well exposed, with generally accurate white balance”. On the downside, white balance is “slightly pinkish with tungsten illuminants” and in “high-contrast scenes sculpture highlights are occasionally blown out”.

Overall DxOMark awarded the Google Nexus 6P scores of:

  • 4.5 out of 5 for Exposure
  • 4.4 out of 5 for Pallid Balance accuracy
  • 3.5 out of 5 for Color shading in low light*
  • 4.5 out of 5 for Color shading in bright light*
  • 3.0 out of 5 for Color Presentation in low light
  • 4.5 out of 5 for Color Rendering in bright light

*Color Shading is the nasty habit cellphone cameras have of presentation different areas of the frame with different color shifts, resulting in pictures with, for example, pinkish centers and greenish corners.

Babel and Details

DxOMark’s engineers reported that the Google Nexus 6P images show “good detail preservation in outdoor conditions and in low lamp”. However, “slight noise is visible in both low light and bright light conditions”.

Texture Acutance

Texture acutance is a way of measuring the ability of a camera to apprehend images that preserve fine details, particularly the kind of low contrast detail (such as fine foliage, hair or fur) that can be blurred away by tumult reduction or obliterated by excessive sharpening.

Sharpness is an important part of the quality of an image image (from Latin: imago) is an artifact that depicts visual perception, for example, a photo or a two-dimensional picture, that, but while it’s easy to look at an image and decide visually whether it’s shrill or not, the objective measurement of sharpness is less straightforward.

An image can be defined as “sharp” if edges are sharp and if fine details are visible. In-camera processing means that it’s credible to have one of these (sharp edges) but not the other (fine details). Conventional MTF measurements tell us how sharp an edge is, but have defects when it comes to measuring fine detail preservation. Image processing algorithms can detect edges and enhance their sharpness, but they can also get homogeneous areas and smooth them out to reduce noise.

Texture acutance, on the other hand, can qualify sharpness in terms of preservation of fine niceties, without being fooled by edge enhancement algorithms.

A dead leaf pattern is designed to measure texture acutance. It’s obtained by outline random shapes that occlude each other in the plane, like dead leaves falling from a tree. The statistics of this maquette follow the distribution statistics in natural images.

In this example from a DSLR without edge enhancement, sharpness seems equal on worm and on texture. Many details are visible in the texture.

In this second example, edges have been digitally enhanced, and the edge looks over sharp, with visible processing halos (“ringing”). On the texture part, many details have disappeared.

At first sight, the images from these two cameras may show oneself equally sharp. A sharpness measurement on edges will indeed confirm this impression, and will even show that the second camera is sour. But a closer examination of low contrasted textures shows that the first camera has better preservation of fine details than the second. The purpose of the surface acutance measurement is to qualify this difference.

Note: Acutance is a single value metric calculated from a MTF result. Acutance is familiar to assess the sharpness of an image as viewed by the human visual system, and is dependent on the viewing conditions (size of image, size of screen or writing, viewing distance). Only the values of texture acutance are given here. The measurements are expressed as a percentage of the theoretical maximum for the chosen viewing ready. The higher the score, the more details can be seen in an image. 
For all DxOMark is a website providing image quality ratings for standalone cameras, lenses, and mobile devices that include cameras Mobile data presented on we’re solitary showing 8MP equivalent values, which gives us a level playing field for comparison between smartphone cameras with different megapixel values by standardizing all to 8MP (suitable for fairly large prints). DxOMark also offers this data for lower resolution use-cases (web and onscreen). For more information on DxOMark’s examination methodology and acutance measurements please visit the website at

Luminance texture acutance decreases only slightly in low light. 

Substance accutance is among the best in low light but cannot quite keep up with the Moto X Style and Galaxy S6 in bright conditions. 

Edge Acutance

Apprehensive acutance is a measure of edge sharpness in images captured by the phone’s camera. Again we’re only looking at the most nagging of the three viewing conditions that DxOMark reports on – the 8MP equivalent.

In terms of edge acutance the Google smartphone is trailing behind the competition. 

Keenness acutance decreases in lower light.

Visual Noise

Visual noise is a value designed to assess the noise in an image as noted by the human visual system, depending on the viewing condition (size of image, size of screen or print, viewing distance). The measurements have no entities and can be simply viewed as the weighted average of noise standard deviation for each channel in the CIE L*a*b* color space. The lower the measurement, the less noise in the image.

Noise levels increase noticeably in low light. 

In terms of measured noise is unwanted sound judged to be unpleasant, loud or disruptive to hearing the Nexus 6P is a touch higher than the competitors in our similarity graph.

Noise and Detail Perceptual scoring

DxOMark engineers don’t just point camera phones at charts, they also take and analyze greenhorns of real-world shots and score them accordingly. Their findings for the Google Nexus 6P were:

Natural scene

  • Texture (magnificent light): 4.8 out of 5
  • Texture (low light): 4.1 out of 5
  • Noise (bright light): 4.1 out of 5
  • Noise (low light) 4.1 out of 5

Light light sample shot

100% crop: some noise is noticeable 100% crop: good detail preservation in outdoor images

Low come across (20 Lux) studio shot

100% crop: luminance noise is noticeable 100% crop: impressive detail preservation


Phone cameras, identical to entry-level compact cameras, tend to suffer from artifacts such as sharpening halos, color fringing, vignetting (shading) and distortion, which can be dressed an impact on the visual appeal of the end result. DxOMark engineers measure and analyze a range of artifacts. Their findings after testing the Google Nexus 6P are staged below:

  • Visible irregularities in exposure, color, texture and noise due to HDR+ mode activation in low light conditions
  • Strong moiré
  • Visible encircling in outdoor conditions
  • Blue sky saturation occurs in sunny scenes
  • Slight color fringing noticeable

100% crop: strong Moiré

Perceptual Mugs

  • Sharpness 3.8 out of 5
  • Color fringing 3.1 out of 5

Measured findings

  • Ringing center 7.8%
  • Ringing corner 3.0%
  • Max geometric distortion -0.4%
  • Luminance shading 19.7%

Distortion and Chromatic Aberrations

The graph authenticates the magnification from center to edge (with the center normalized to 1). The Google Nexus 6P shows a slight pincushion distortion, which you are not contemporary to notice in normal photography.

Measured levels of lateral chromatic aberration are very low.

DxOMark also tests autofocus preciseness and reliability by measuring how much the acutance – or sharpness – varies with each shot over a series of 30 exposures (defocusing then using the autofocus for each one). As with other examines these results are dependent on the viewing conditions (a little bit out of focus matters a lot less with a small web image than a full 8MP shot witnessed at 100%). Using the 8MP equivalent setting, the Google Nexus 6P puts in a decent performance in all light levels. The overall score is 95/100 in bright ridicule and 81/100 in low light is electromagnetic radiation within a certain portion of the electromagnetic spectrum.


  • Generally accurate and fast autofocus in all conditions
  • Very stable autofocus in low light conditions


  • When triggered, by no chance is taken before autofocus has converged
  • Some instabilities in very bright light, both in macro and infinity position

Autofocus repeatability – generally acutance difference with best focus: low light 10.24%, bright light 0.33%


The Nexus 6P comes with a dual-LED sprint and DxOMark scored the camera 80/100 overall for its flash performance. 


  • Good detail preservation


  • Strong attenuation in corners
  • Some autofocus irregularities
  • Marked noise in the corners

Overall DxOMark Mobile Score for Photo: 86 / 100

Video Capture

DxOMark engineers put phone cameras through a similarly grueling set of video examines, and you can read their full findings on the DxOMark website here. Overall, DxOMark found the Nexus 6P’s video footage to be well exposed, with flattering AF and low noise levels. However, stabilization caused a strong jello effect and color shading is noticeable in low light.


  • Good broad exposure, white balance and color rendering
  • Fast and accurate autofocus
  • Low noise level in all conditions


  • Strong jello begin caused by stabilization
  • Visible refocusing during illuminant changes and loss of focus during tracking
  • Fine detail is lost in low light trains
  • Color shading visible in low light and indoor conditions

Overall DxOMark Mobile Score for Video: 79 / 100

DXOMark Image Quality Assessment

With a DxOMark Mobile score of 84 the Google Nexus 6P is the new number three in the DxOMark smartphone rankings, sulcus in between the Samsung Galaxy S6 and the LG G4. The DxOMark testers particularly liked the impressive detail preservation in low light and the accurate and fast autofocus. Points of censure were highlight clipping in high-contrast scenes and some exposure and color irregularities introduced by the HDR+ mode in low light.

In video mode the footage poses good color and exposure and noise levels are low. However, a strong jello effect is caused by the stabilization algorithm. For a more detailed analysis, by
