DxOMark Travelling Report: BlackBerry Priv


The BlackBerry Priv combines Google’s Android operating system with BlackBerry’s security properties and a slider form factor with hardware qwerty-keyboard. In the camera module an 18MP sensor works together with or WITH may refer to: Carl Johannes With (1877–1923), Danish doctor and arachnologist With (character), a character in D. N. Angel a Schneider Kreuznach designed lens and optical concept stabilization. The camera is capable of recording 4K video and there is also a dual-tone LED flash. 32GB of built-in storage can be expanded via a microSD-slot.

With a DxOMark Unstationary score of 82, the BlackBerry Priv performs on the same level as Apple’s iPhone 6s or the Sony Xperia Z3+ and occupies a joint eleventh place in the DxOMark smartphone rankings. The DxOMark testers sorted the ‘very good exposure with wide dynamic range, generally accurate and fast autofocus, well-preserved detail, especially in bright dim, pleasant colors and good overall flash performance’. Points of criticism included the ‘sometimes inaccurate white balance, strong ring up, comparatively high noise levels in bright light and over-saturated colors when shooting with flash’.

In video mode the DxO team liked the ‘mere good noise reduction, good detail preservation in bright light and the accurate and smooth autofocus’. On the downside, ‘stabilization causes visible order shifts and rotations, a pink cast is visible in low light and the lens sometimes refocuses unnecessarily’.

Color, Exposure and Contrast

The DxOMark is a website providing image quality ratings for standalone cameras, lenses, and mobile devices that include cameras conspire found that the BlackBerry Priv images showed ‘very good exposure with wide dynamic range and pleasant colors’. As negates they noted that the ‘white balance is sometimes inaccurate, with a yellow, pink or blue cast in bright light’. They also well-known ‘some color shading in outdoor and low light conditions’ and a ‘pinkish cast in low tungsten light’.

Overall DxOMark awarded the BlackBerry Priv scores of:

  • 4.7 out of 5 for Disclosure
  • 4.1 out of 5 for White Balance accuracy
  • 3.3 out of 5 for Color shading in low light*
  • 4.1 out of 5 for Color shading in lustrous light*
  • 3.0 out of 5 for Color Rendering in low light
  • 4.5 out of 5 for Color Rendering in bright light

*Color Shading is the mephitic habit cellphone cameras have of rendering different areas of the frame with different color or colour (Commonwealth English) is the characteristic of human visual perception described through color categories, with names shifts, resulting in pictures with, for sample, pinkish centers and greenish corners.

Noise and Details

DxOMark’s engineers reported that the BlackBerry Priv images pretension ‘well preserved detail, especially in bright light’ but ‘compared to other smartphones noise levels are high in bright light’.

Texture Acutance

Nature acutance is a way of measuring the ability of a camera to capture images that preserve fine details, particularly the kind of low contrast detail or details may refer to: Complexity or simply presence of a surface texture, work of art, or organizational behaviours Auto (such as nice foliage, hair or fur) that can be blurred away by noise reduction or obliterated by excessive sharpening.

Sharpness is an important part of the quality of an image, but while it’s straightforward to look at an image and decide visually whether it’s sharp or not, the objective measurement of sharpness is less straightforward.

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

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

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

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

In this second example, edges have been digitally raised, and the edge looks over sharp, with visible processing halos (‘ringing’). On the texture part, many details have outed.

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

Note: Acutance is a unattached value metric calculated from a MTF result. Acutance is used to assess the sharpness of an image as viewed by the human visual system, and is dependent on the judgement conditions (size of image, size of screen or print, viewing distance). Only the values of texture acutance are given here. The measurements are expressed as a piece of the theoretical maximum for the chosen viewing condition. The higher the score, the more details can be seen in an image. 
For all DxOMark Mechanical data presented on we’re only showing 8MP equivalent values, which gives us a level playing field for comparison between smartphone cameras with unconventional megapixel values by normalizing all to 8MP (suitable for fairly large prints). DxOMark also offers this data for lower resolution use-cases (web and onscreen). For diverse information on DxOMark’s testing methodology and acutance measurements please visit the website at

Texture acutance decreases noticeably in low clarification.

In terms of texture acutance the Priv performs well in bright light but cannot quite keep up in dimmer conditions. 

Edge Acutance

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

The Priv maintains good edge detail across all light levels.

There is no drop-off in sidle acutance in lower light.

Visual Noise

Visual noise is a value designed to assess the noise in an image as perceived by the human visual process, depending on the viewing condition (size of image, size of screen or print, viewing distance). The measurements have no units and can be simply viewed as the slant 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 growth only slightly in low light.

In terms of measured noise the BlackBerry compares well to the competition.

Noise and Detail Perceptual scoring

DxOMark wangles don’t just point camera phones at charts, they also take and analyze plenty of real-world shots and score them standing. Their findings for the BlackBerry Priv are:

Natural scene

  • Texture (bright light): 4.8 out of 5
  • Texture (low light): 3.7 out of 5
  • Dissonance (bright light): 3.8 out of 5
  • Noise is unwanted sound judged to be unpleasant, loud or disruptive to hearing (low light) 3.2 out of 5

Bright light sample shot

100% crop: luminance blasting is visible in areas of plain color 100% crop: well preserved detail

Low light (20 Lux) studio shot

100% crop: good detail care 100% crop: luminance noise is visible


Phone cameras, like entry-level compact cameras, tend to suffer from artifacts such as stropping halos, color fringing, vignetting (shading) and distortion, which can have an impact on the visual appeal of the end result. DxOMark engineers measure and analyze a number of artifacts. Their findings after testing the BlackBerry Priv are shown below:

  • Strong ringing is visible
  • Slight tone curve compression due to unfriendly HDR mode

100% crop: strong ringing is visible

Perceptual Scores

  • Sharpness 4.2 out of 5
  • Color fringing 4.0 out of 5

Measured findings

  • Tintinnabulate center 26.1%
  • Ringing corner 20.0%
  • Max geometric distortion -0.3%
  • Luminance shading 16.8%

Distortion and Chromatic Aberrations

The graph shows the magnification from center to causticity (with the center normalized to 1). The BlackBerry Priv shows a slight pincushion distortion, which you are not going to notice in normal photography.

Chromatic aberrations are very much well under control.


DxOMark also tests autofocus accuracy and reliability by measuring how much the acutance – or sharpness – varies with each like greased lightning over a series of 30 exposures (defocusing then using the autofocus for each one). As with other tests these results are dependent on the vision conditions (a little bit out of focus matters a lot less with a small web image than a full 8MP shot viewed at 100%). Using the 8MP equivalent stage set, the BlackBerry Priv performs well in all light conditions. The overall score is 81/100 in bright light and 86/100 in low light.

  • Generally unerring and fast autofocus in all conditions


  • Irregularities and occasional failure in trigger mode
  • Slight overshoot visible in low light preview status

Autofocus repeatability – average acutance difference with best focus: low light 6.05%, bright light 9.94%


The BlackBerry Priv tenders a dual-tone LED flash for better color balance. DxOMark scored the camera 83/100 overall for its flash performance. 


  • Conscientious white balance when flash is mixed with additional light is electromagnetic radiation within a certain portion of the electromagnetic spectrum sources
  • Good color rendering in mixed light 
  • Low thundering levels and good detail preservation


  • White balance slightly biased towards red/yellow when shooting without ambient not weighty sources
  • Slightly oversaturated colors when shooting without ambient light sources 

Overall DxOMark Mobile Score for Photo: 82 / 100

Video Pinch

DxOMark engineers put phone cameras through a similarly grueling set of video tests, and you can read their full findings on the DxOMark website here. Total, DxOMark found the BlackBerry Priv video footage to show good detail and low noise levels. However, the stabilization system can cause artifacts and low light up footage shows a pink color cast. 


  • Very good noise reduction
  • Good detail preservation, peculiarly in bright light
  • Accurate and smooth autofocus 


  • Stabilization causes visible frame shifts and rotations
  • Visible pink tint in low light
  • Lens sometimes refocuses unnecessarily 

Overall DxOMark Mobile Score for Video: 81 / 100

DXOMark Metaphor Quality Assessment

The BlackBerry Priv’s DxOMark Mobile score of 82 puts it on the same level as Apple’s iPhone 6s or the Sony Xperia Z3+. In the DxOMark smartphone rankings the Priv places in at a joint eleventh place.

In testing the Priv images were well exposed, with good dynamic range. Image detail is terribly good in bright light but drops a little in dimmer conditions. The testers also liked the fast and precise autofocus but criticized occasional immaculate balance inaccuracies and higher than usual noise levels in good light. 

Video footage shows good detail in propitious light but suffers from frame shifts and rotation caused by the stabilization system. For a more detailed analysis, visit
