Selecting the right components plays an important role in the ultimate performance of a smartphone. Raw is a new standard for smartphone camera modules that can help component makers to design better components and phone manufacturers to select better modules for their phones. The test protocol is based on objective measurements of sensor, lens, and module sensitivity on Raw data. This new addition to the Analyzer testing suite contains a dedicated test setup and Raw scripts that generate an overall score for module performance, as well as a detailed report containing test data for various attributes of image quality. And if you have DXOMARK’s experts certify your laboratory setup, your Image Quality engineers will stay updated with the latest features and capabilities of the Raw module.

HDR Noise Chart
The HDR Noise chart measures SNR, dynamic and tonal ranges, and tone curves. The chart contains 28 natural density patches that deliver a 120 Ev test scene and 5 polarizers for exposure adjustment. You can also use the ISO saturation method to take measurements that are fully compliant with ISO standard 12232. (Also used with Photo module.)
ColorChecker chart with its grey frame
Chart framed for automatic detection in all scenes; facilitates measurement from RAW data of color response and color sensitivity. (Also used with Video & Stabilization module.)
This glass-supported dot-pattern chart with very flat surface ensures precise optical measurements of lateral chromatic aberration, distortion, and focal length from one shot. Available in various sizes and compatible with most types of cameras. (Also used with Dual-Cam & 3D Camera module.)
A uniform gray-colored chart for evaluating lens shading. (Also used with Video & Stabilization module.)
Universal LED Timer
A device with 5 computer-controlled LED arrays for measuring and automatically analyzing (with Analyzer software) exposure time, electronic rolling shutter. (Also used with Selfie module.)
Spectralight QC Setup
The Spectralight QC Setup is our most compact and cost-effective lighting setup solution, ideal for small labs with limited budget. Its metal frame makes it stable, durable, and safe. Its light weight makes it of easy movement and fixation. Its light sources are temperature-adjustable and fully dimmable for a wide range of testing conditions.
The Flare Bench is a measurement setup that can generate realistic flare images in a lab setup. The setup incorporates a bright light source, close in apparent size and color temperature to the sun. It measures Flare Attenuation by processing RAW images taken on the device being tested. It is an automated compact table-top setup, that is easy to move as it is independent of other lab equipment. With a capacity to rotate from -90° to +90°.
Rich color rendition and color depth matter a lot when shooting portraits. The best image quality metric that correlates with color depth is color sensitivity. Color sensitivity reports in bits the number of colors that the sensor is able to distinguish. The higher the color sensitivity, the more color nuances there can be in the picture.
Noise & Contrast
Unique to Analyzer is its specialized HDR Noise testing hardware that provides accurate measurements of Signal-to-Noise Ratio, Dynamic Range and Tonal Range in scenes with up to 120 Ev (1,000,000:1) contrast between its brightest and its darkest part. All individual density patches of our HDR Noise chart are uniform, so you don’t need to defocus between shots to get accurate results. Furthermore, this chart can be used to measure ISO sensitivity per standard ISO12232.
Vignetting (Luminance & Color Shading)
Analyzer measures vignetting for RAW data (where available) under a variety of lighting conditions. It also measures and characterizes color shading caused by many sources—including IR filter or micro-lens array alignment problems or imperfections, sensor cross-talk, lens tilt or shift, and even sensor design—and generates a complete field map per color channel.
Horizontal & Vertical MTF
Analyzer includes a slanted-edge “checkerboard” chart for measuring MTF across the entire image field both horizontally and vertically. You can use the same test image for measuring astigmatism, longitudinal chromatic aberrations.
The SNR10 measurement evaluates the amount of light in the scene the device under test needs to take pictures of acceptable quality. A good device will be able to take acceptable pictueres (meaning, with a good signal-to-noise ratio) with barely a few lux of light, while a less performant device might require a few hundreds. This gives an intuitive alternative view of the SNR measurement, highly correlated with the user experience.
Analyzer’s Flare Bench can be used to measure the Flare Attenuation Curve, an easy-to-understand metric that evaluates the amount of flare that can be generated by a lens. This measurement is based on RAW images.
Distortion & Lateral Chromatic Aberration
A high-fidelity IEEE-CPIQ dot chart provides the basis for measuring both geometric distortion and lateral chromatic aberration as they vary by field radius. Results are displayed in table, chart, and graph formats.
To capture motion in low-light, one has to prioritize exposure time and increase ISO. This results in a decreased Signal-to-Noise ratio (SNR). The low-light ISO metric determines to what extent ISO can be increased without compromising image quality. Measured using Analyzer’s HDR Noise chart, Low-light ISO is the highest ISO setting for a camera that allows it to achieve a SNR of 30dB while keeping a good dynamic range of at least 9 EVs and a color depth of at least 18bits. Low-light ISO is an open scale.
