Imatest sent two engineers to the IEEE P2020 Automotive Imaging Quality face-to-face meeting in Dusseldorf, Germany this past February in 2019. The IEEE P2020 standard, which is still in development, aims to define KPIs and test procedures to address the many challenges relevant (and often unique) to automotive imaging. (more…)
Witnessing the Aurora Borealis should be at the top of every photographer’s bucket list. This guide details the most important considerations for capturing images of the Northern lights. To be successful, you’ll need to be in the right place at the right time, equipped with the right camera and a decent amount of luck on your side.

The IEEE-SA P2020 is a working group for automotive imaging standards. Its goal is to define a set of standards to resolve the current ambiguity in the measurement of image quality in automotive imaging systems. (more…)

Consistency is a fundamental aspect of successful image quality testing. Each component in your system may contribute to variation in test results. For tasks such as pass/fail testing, the primary goal is to identify the variation due to the component and ignore the variation due to noise. Being able to accurately replicate test results with variability limited to 1-5% will give you a more accurate description of how your product will perform. (more…)
We now offer a complete, customizable image quality testing solution for security camera systems to provide our customers with an easy, effective way to outfit their labs. While working with some of the top security camera manufacturers, our engineers have compiled all of the necessary lab materials in a convenient package. (more…)
In this post, we will be using the Contrast Resolution Chart and Imatest Master to measure the dynamic range of a Google Pixel 2 XL. The dynamic range of a camera is the reproducible tonal range in an imaging system. Put simply, it is the range between the darkest black and the brightest white of an image and is typically measured in decibels (dB). (more…)
The obsolete ISO 12233:2000 standard defines a resolution test target with a high contrast ratio. These are typically produced at the maximum dynamic range of a printer, which can be anywhere from 40:1 to 80:1. The high contrast can lead to clipping of the signal which leads to overstated invalid MTF values. (more…)
The dynamic range of recent HDR image sensors, defined as the range of exposure between saturation and 0 dB SNR, can be extremely high: 120 dB or more. But the dynamic range of real imaging systems is limited by veiling glare (flare light), arising from reflections inside the lens, and hence rarely approaches this level. (more…)
The release of Imatest 5.0 introduced a number of powerful new features, including the Arbitrary Charts module which enables Imatest analysis of test chart designs which would be otherwise unsupported by the software. This new module allows user-defined chart layouts for any situation which requires one. (more…)
As of Imatest 5.0, Imatest Master now features image acquisition capabilities. Previously, image acquisition capabilities were supported by Imatest IS, which has been discontinued as a separate product. This provides all of our customers with access to the acquisition library. The library supports direct acquisition from a wide range of frame grabbers and cameras, as well as industry standard interfaces. Direct image acquisition cuts out several steps in the image quality testing process and allows for in-the-loop testing with Imatest.
As predicted by astronomers years in advance, a peculiar cosmic event will occur on the morning of August 21st. Passing directly in front of the sun, the moon will cast a shadow racing across North America at supersonic speeds. From Salem, Oregon to Charleston, South Carolina, the 70 mile wide shadow will darken everything in its path. Outside the path of totality, all of North America will still be able to observe a partial solar eclipse! (more…)
Imatest was recently featured in Automoblog.net’s article, Three Companies Changing the Autonomous Driving Landscape. Carl Anthony writes:
“With driverless cars, the implication is huge because cameras will play a vital role in the forthcoming autonomous world. In order for autonomy to deliver on its promises of reducing collisions and traffic fatalities, image quality is essential. Imatest takes this into consideration as today’s automotive trends usher us further into autonomy.”
