Industry’s first HDR testing system supports up to 120dB
An increasing number of cameras feature an integrated high-dynamic-range (HDR) shooting mode. Because these modes combine multiple frames at varying exposures, the cameras can capture much greater extremes of light in a scene than was previously possible. Traditional paper targets are completely insufficient to measure the effectiveness of HDR imaging. DxO Analyzer v6 introduces a new hardware tool and software support that allows it to accurately test images of scenes with dynamic ranges up to 120dB – more than enough to accurately measure and analyze camera HDR modes.
Automated lighting system speeds testing while reducing errors
Precise control of lighting is essential for accurate image quality measurement and device calibration. Manually measuring the incident light falling on test targets and then making corresponding adjustments to the lab lights is a time-consuming and error-prone process. Because lights are never perfect, and their output is not completely stable, test setups need to be checked and tweaked in this manner repeatedly during an analysis session. DxO Analyzer 6 addresses this problem by providing a closed-loop automatic lighting adjustment system that relies on accurate light meters, placed in the scene, to measure the light falling on test charts and then automatically adjusting the light level until the illuminance values are within the required tolerances.
Video analysis now includes exposure, white-balance, sharpness and texture with changing lighting
As video capture becomes a more important and more integrated part of camera designs, it is important that testing solutions keep up. DxO Analyzer v6 greatly expands the testing of video quality by using a multi-pattern texture chart, measured under changing light color temperatures and levels. This allows accurate testing of many additional aspects of video, including exposure, white-balance, sharpness, and texture all in one go. These are valuable to all camera buyers, but are especially important in many commercial applications such as automotive ADAS (Advanced Driver Assistance System), surveillance, medical, videography, and aerospace.
New MTF-based calibration allows testing higher resolutions
Traditionally, MTF testing using paper targets assumes that both the printing on the target and the paper used for the target are perfect and present an ideal black-white edge with infinite resolution. Unfortunately, ink or photographic edges are never perfect and paper always has some of its own texture, with the result that MTF for cameras and lenses measured this way is not accurate. In DxO Analyzer v6 we have analyzed our test targets to measure the MTF of the target itself. Analyzer then corrects the results of its MTF tests using this correction factor as a calibration, so that the results more accurately reflect the MTF of the device being tested. This additional accuracy is particularly important as sensor resolutions continue to increase.

Understanding ERS artifacts
All CMOS sensors feature an ERS which introduces many kinds of artifacts and distortions that particularly affect moving objects, resulting in wobble or jello effects, skew, smear, or partial exposure. DxO Analyzer uses advanced image processing technologies to deliver the first automated characterization of distortions produced by electronic rolling shutters. The exposure time range and the precision of the DxO Labs solution are unique features on the market.
Exclusive DxO Analyzer timer
The unique DxO LED Universal Timer, coupled with electronic triggers to control touch-screen or mechanical shutter camera products (DSC, DSLR, smartphone, tablet, camcorders, camera modules, etc.), enables a smooth testing workflow. The automatic processing of test shots is also more accurate than any competitive solution, thanks to the DxO LED Universal Timer’s smaller and faster LED cells, and it’s the first commercial solution designed to trigger touch-screen shutters without any moving parts!
DxO Analyzer, the reference solution for video and still image quality evaluation
With its unique video stabilization, motion artifact, and 3D camera measurement features, DxO Analyzer provides camera engineers, designers, and marketers a complete and reliable solution for testing, sourcing, and tuning their products for both video and still image quality.
