DxO Analyzer solutions can be configured with up to five Modules to meet your image quality testing requirements

Optics Module

Whether your device is an embedded imager or a standalone camera, the quality of its optics will play a major part in determining the quality of images it can capture. DxO Analyzer’s Optics Module provides everything you need to fully characterize the performance of your Optics including testing both Raw and JPEG image capture.

Blur / Sharpness

Going beyond standard MTF measurements to provide a perceptual measure of image sharpness, DxO Analyzer utilizes DxO’s unique BxU (Blur eXperience Unit) to provide a meaningful measure of sharpness at twenty-five locations throughout the image. The resulting output sharpness map is an ideal for diagnosing optical alignment issues.

MTF (Radial)

In addition to traditional horizontal and vertical MTF test charts, DxO Analyzer includes an IEEE-CPIQ and ISO 12233-compliant low-contrast chart for measuring radial MTF. These test charts are also calibrated with DxO Analyzer software.

Vignetting (Luminance & Color Shading)

Making use of the same dot chart images, vignetting is measured by channel for both the Raw data (where available) and the finished RGB image, under a variety of lighting conditions. Color shading, caused by many sources − including IR filter or micro-lens array alignment or imperfections, sensor cross-talk, lens tilt or shift, or even sensor design — is measured and characterized with a complete field map per color channel.

Included charts and equipment

  • DOT chart DxO_DU0002_120

  • MTF chart DxO_SU0002_120

  • Radial MTF chart DxO_SFU0002_120

  • Color Fringing chart DxO_CF0001_32

MTF (Horizontal & Vertical)

DxO Analyzer includes a slanted-edge, “checkerboard”, chart for measuring MTF in both horizontal and vertical directions, across the entire image field. The same test image can be used for measuring astigmatism, longitudinal chromatic aberrations, and ringing. In addition, the most recent version of DxO Analyzer software compensates for chart-limited MTF.

Ringing & Color Fringing

Using edge profiles on its ISO #12233-compliant MTF chart, the Optics Module measures ringing artifacts to help you evaluate and tune your sharpening algorithms. The Optics Module also includes a custom Color Fringing transmissive chart that provides measurements of color inaccuracies caused by chromatic aberration − that are especially visible in highly saturated areas.

Effective Focal Length

By measuring the relative magnification of a field of dots across a test chart, DxO Analyzer measures the Effective Focal Length of your lens across its entire image field.

Flash: tests are also provided in the Optics module, helping you evaluate your flash solutions for both Uniformity and accuracy of White Balance.

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 graphics formats.

Photo Module

In tandem with the optics, the sensor, and the Image Signal Processing (ISP) in your device will determine overall image quality. DxO Analyzer’s Photo Module provides the pieces you need to fully evaluate the quality of image capture and processing. By providing a full set of tests for texture details, noise, and sharpness, DxO Analyzer’s Photo module allows you to make informed tradeoffs between them in your camera design − especially how it handles low-light situations.

Texture & Acutance

One of the most important, and visible, measurements of image quality is the ability to accurately capture texture and edges. The Photo Module provides software and charts that provide Texture MTF and acutance, as well as Edge MTF and Acutance. Texture is measured using the provided reflective “dead leaves” chart that is IEEE-CPIQ compliant.

Tone curve

By varying the illumination, the Photo Module provides a complete picture of the tonal response of your device. This is an excellent way to benchmark both the linearity of sensor response and gamma of the encoded JPEG.

Dead / hot pixels (Raw)

The Photo Module identifies both dead and hot pixels found in Raw image captures, so that you can gather quality statistics or map them out as needed.

Color Sensitivity

By extending the notion of dynamic range to color, DxO Analyzer provides a measure of the color sensitivity of a sensor by calculating the total number of colors it can distinguish, subject to noise. The value is reported out as the number of bits required to encode all those colors.

Included charts and equipment

  • Dead Leaves chart DxO_TU0003_78

  • HDR chart DxO_HDR0001 (120dB)

  • Kinoflo Celeb 200 DMX (LED light-table)

  • Color Checker chart (X-rite) with frame

  • Automated Lighting System (optional extra)

Noise & Contrast

One of the most important, and visible, measurements of image quality is the ability to accurately capture texture and edges. The Photo Module provides soft and graphics formaware and charts that provide Texture MTF and acutance, as well as Edge MTF and Acutance. Texture is measured using the provided reflective “dead leaves” chart that is IEEE-CPIQ compliant.

Unique to DxO Analyzer is specialized HDR testing hardware that provides accurate contrast measurements − including tonal ranges and tone curves − up to 120dB (1,000,000:1) for testing your device’s extended-dynamic-range capabilities. All individual density patches of our HDR chart are uniform, so no defocusing is required to get accurate results. ISO sensitivity can also be measured according to ISO standard #12232.

Row / Column noise

Stripe noise, either in rows or columns, is much more visible than random noise, so controlling it is very important in achieving an effective camera design. DxO Analyzer measures both row and column noise by performing frequency analysis in both dimensions − charting the results and allowing you to easily spot issues.

ISO Sensitivity (compatible with ISO 12232)

The Photo Module measures and charts actual gain compared to changes in light levels, consistent with ISO standard 12232.

Color

The accuracy of your device’s Auto White Balance (AWB) is automatically calculated using DxO’s (optional) proprietary closed-loop lighting control system featuring a range of industry-standard illuminants with a standard ColorChecker chart. Once the white balance is calculated, color fidelity and Metamerism Index are also measured. The lighting system also makes it simple to measure color fidelity and sensitivity under a variety of lighting spectrum and illumination levels − down to just a few Lux.

Video & Stabilization Module

Evaluating video quality requires additional, specialized, hardware and software. DxO’s Video & Stabilization module provides all of the technology you need. It includes hardware, software, and charts for evaluating motion-related issues, the stability of video quality in changing environments, and general video quality.

Photo stabilization

The effectiveness of Image stabilization systems − whether optical or electronic − is typically measured in stops. The Video & Stabilization module supports the CIPA protocol for performing this test. Combined with our optional shaking platform, the tests are not only simple to complete, but very repeatable, and operator-independent. The module is also able to measure the linear effect of motion blur.

Optional shaking (stabilization) platform

Camera and subject motion are two of the hardest aspects of video quality to measure in an accurate and repeatable way. DxO’s Video module works seamlessly with our purpose-built Hexapod shake table and control software to give you confidence that you’re testing your device under a variety of types of camera movement.

Video on textured chart

Rapidly changing lighting conditions represent a challenge for the Autoexposure (AE) and Auto White Balance (AWB) features of video capture devices. DxO’s Video module evaluates how quickly and accurately your AE & AWB respond to changes in lighting using the included textured chart. Sharpness and texture-preservation are measured at the same time, for more efficient testing workflow.

Included charts and equipment

  • Dead Leaves chart DxO_TU0003_78

  • Uniform Grey chart

  • Hexapod stabilization platform + controller (optional extra)

Video stabilization

Measuring video stabilization is a more complex process than measuring it for still images. The Video & Stabilization module helps you characterize your device’s effectiveness in a variety of ways. Translation, rotation, residual motion, and motion blur are all measured and reported out by time and frequency. In addition, deformation due to Electronic Rolling Shutter is measured.

Video on uniform chart

Consistency of video performance during a recording is critical for producing quality results. The Video & Stabilization module performs an extensive set of tests during the recording of a uniform background to help you characterize your camera’s video stability. These include measuring the variation in exposure and white balance, as well as color shifts. Temporal and spatial noise are also measured, including row and column noise. To facilitate easy measurement, the module automatically handles a variety of input formats including Raw, AVI, TIFF, and JPEG.

Autofocus & Timing Module

Autofocus testing setup

Users expect to have fast and accurate autofocus. DxO Analyzer lets you characterize your camera’s autofocus effectiveness with the greatest depth and precision.
DxO Analyzer AF measurements use the DxO Texture chart and the DxO Universal LED Timer to characterize camera AF sharpness, repeatability, time lag, and acutance irregularity.
Other advanced autofocus testing features:

  • Compatible with all AF technologies

  • Automated image capture

  • Simple, robust, and straightforward workflow

  • Suitable for testing even the most powerful AF systems

Video timing measurement

Simply shooting still charts won’t help you understand the real-time dynamics of your camera system. Even for single-image photography, electronic rolling shutters will produce artifacts that need to be characterized and minimized. For video capture the requirements include maintaining frame rate, avoiding missing frames, and keeping blanking intervals accurate. Through the use of a specialized piece of proprietary timing hardware, closely integrated with custom testing software, DxO Analyzer’s Timing Module allows you to measure and tune all these important characteristics.

Still timing measurement

Our Timing Module also allows you to measure the time before the shutter is released, and shot-to-shot time lag, benchmark numbers that can be very important in camera reviews.

Included charts and equipment

  • DxO LED Universal Timer

  • Touchscreen & Mechanical Triggers

DxO LED Universal Timer

Coupled with specialized electronic triggers that work with both touchscreen and mechanical shutter cameras, the unique DxO LED Universal Timer makes it possible to automate the accurate testing of the timing of your camera. This includes measuring shutter lag, shooting time lag including focusing time, shutter open and close times, and rolling shutter issues.

Dual-Cam & 3D Module

Traditional image quality measurement and tuning tools are not sufficient for camera modules that include more than a single sensor. It is necessary to calibrate the positions of all the imagers, for example. Whether you are planning to use an array of imagers or a pair of cameras to provide a 3D view of the world or a depth map for advanced gesture-based user interfaces, DxO Analyzer’s Array & 3D Camera Module will help you benchmark and tune your product.

When using the optional DxO-proprietary 3D Bench and DxO DOT chart, all of these measurements can be performed with just two test shots − reducing setup time from nearly 30 minutes to about 1 minute.

Camera pose

External calibration metrics include full 6-axis camera pose measurement (including 3 axes of rotation & 3 axes of translation) for accurate 3D scene reconstruction.

Distortion curves

The Array & Dual 3D module also provides distortion profiles and polynomial models for multiple imagers to allow more precise image registration.

Focal points & Focal lengths

Internal calibration metrics include measuring the actual focal length of each imager as well as the focus points in the image field.

Included charts and equipment

  • DOT chart DxO_DU0002_120

  • 3D camera test bench with accessories (optional extra)
