Imatest Releases Stray Light (Flare) Analysis with Upcoming Version 22.2

September 13th, 2022, Brussels, Belgium, and Boulder, CO. Imatest announced at AutoSens Brussels the release of its new stray light (flare) testing solution, available with Imatest version 22.2. 

 

Stray light, also known as flare, is any light that reaches the detector (i.e., the image sensor) other than through the designed optical path. Stray light can be thought of as systematic, scene-dependent optical noise. Depending on the mechanism causing the stray light, it can produce phantom objects within the scene (i.e., ghosts/ghosting), reduce contrast over portions of the image (e.g., veiling glare), and effectively reduce system dynamic range. These factors can adversely affect the application performance of the camera in a wide variety of applications including automotive, security, machine vision, and consumer electronics, and is addressed in the upcoming IEEE P2020 standard. The Imatest stray light testing setup allows users to measure stray light for imaging systems.

Imatest Customer Profile: Fabrizio Ghetti

Mia: What do you do for work?

Fabrizio: My job is now video expert in Italian R&D department of Avaya. I lead the video lab that evaluates and measures the image quality of Avaya and Konftel equipment. I started evaluating video conferencing imaging 35 years ago when the Italian company Aethra pioneered the study of still image transmission in telecommunications and, at that time, mobile phones were completely different from the smartphones we use today. The camera we used in the beginning to capture images on computers had very big dimensions and a completely different technology, because both displays and cameras used cathode ray tubes to view and capture images. I have since remained responsible for assessing the quality and specification of videoconferencing imaging and have worked as the head of the video lab for Aethra, Radvision, Konftel and Avaya. In these years, I traveled to Asia among manufacturers of cameras and optics of different types, evaluating the different methods of video testing of the various laboratories.

Mia: As somebody who works with video, that’s really cool to hear. I work with video on the other side of it with production for Imatest marketing. It’s amazing to hear just how far imaging goes.

Fabrizio: Yes, being one of the pioneers, I have seen a lot of technology pass in front of me. We started from the NTSC Signal standard for the US or PAL/SECAM for Europe, to the present 4K, and now in the video communication market we are starting to use even higher resolutions with image sensors up to 50 MPixel, while the technology of mobile phones begin to use 200 MPixel image sensors. Even though I have seen a lot of technology, the concept of image quality remains the same and Imatest remains an important part of my work.

Mia: How long have you been using Imatest software?

Fabrizio: I think I started to use Imatest in 2013. I remember the version 3.10. When I started using Imatest, I not only abandoned the use of the other methods, but I used it with our subcontractors because it’s a good reference. It is important to align the two labs remotely and locally.

Mia: Awesome. Next question: what feature in the software do you find yourself using the most?

Fabrizio: I use a lot of parts of Imatest, but mainly we can say that I concentrate my activity on resolution. So SFR; the test for measuring resolution on your screen and also geometry of the image, the angle of view, and the distortion. The next step is to evaluate the exposure using the step chart. For example, for control of the brightness, contrast, or the color checker to evaluate color occurrences using different illumination types. Of course I also use the Imatest Lightbox to use the lens shading correction so the compensation of the reduction of illumination in the corner. And with this one I can also check the dynamic range. I use the 36 patch low dynamic range chart to evaluate the wide dynamic range. So this is mainly what I use normally.

Mia: Yeah. You’re pretty much using a lot of our charts, especially some good ones to cover all your needs. Well, it’s been really great speaking to you and thank you for all of your insight in the industry regarding video. It’s always very special to be able to interact with customers and hear just how much they’re making an impact in the industry. Thank you very much.

Fabrizio: I wish you a very nice day and good luck in all of your activities. Thank you for your time.

Imatest Customer Profile: Naveen Koul

Mia: The first question is what do you do for work?

Naveen: I’m an image quality engineer. I work mainly on tuning and image quality verification and validation. At present, I’m associated with Nuro.

Mia: How long have you been using Imatest?

Naveen: I have been using Imatest since around 2008.

Mia: Wow, awesome. What feature in the software do you find yourself using the most, or one that you usually gravitate towards?

Naveen: I have mostly used all the features across Imatest. But some features I use are the high dynamic range and noise ones, which are very interesting features Imatest has. Apart from all image quality features, Imatest provides a lot of data in the CSV files and the JSON files, which is quite useful.

Mia: For sure. Do you have any tips for people who are just beginning to use Imatest?

Naveen: Yeah, there’s a lot of very good documentation Imatest provides. Also, I’ve seen a lot of video lectures on YouTube for a beginner to start with and understand the tool well. I will advise, there is a lot of stuff in the CSV and the JSON files which does not get displayed on the images. That is really great data to look at that gives a lot of information about the image quality other than what the output saved images is.

Mia: Yeah, that’s a great bit of information. I make the videos for Imatest that you see on YouTube or on our website, so it’s good to hear they’re helpful. That’s a great idea for a video; showing people how to interpret the JSON files. Thank you so much for doing this!

Naveen: Sure. Thank you.

Imatest announces new Target Generator Library

We are happy to announce the release of the new Target Generator Library today. The Imatest Target Generator is free software that will facilitate rapid, iterative lens and camera design by enabling simulations that can help a designer make better informed decisions about what components are appropriate  in advance of costly prototyping phases.

 

The new Imatest Target Generator provides virtual chart solutions. Quantitative and qualitative results from applying ray tracing, noise effects, and image signal processing to virtual charts aid engineers in communicating the impact of various lens and camera design parameters. Image quality deficiencies can be observed and mitigated using a virtual chart during the simulation phase. Virtual charts can aid engineers in comparing and resolving discrepancies between designs and builds. (more…)

Imatest Customer Profile – Dr. Brian Deegan

Imatest is happy to introduce customer profiles! Each month, we will interview one of our Imatest users to share why they use the software and create a sense of community among our users. Interested in being featured? Reach out to mia@imatest.com.

 

The first customer profile is Dr. Brian Deegan. Based in Ireland, Brian is a long-time user who has utilized the Imatest software across multiple disciplines. Read more about our interview with Brian:

 

Mia: How long have you been using Imatest?

Brian: It must be ten years now at this stage. I started at Valeo in 2011 and have used it throughout my entire career there. I started in university this year and I’m still using it.

Mia: Awesome. And you’re still using it now that you’re at the university?

Brian: Yeah, not as much and not as much directly, but one of the PhD students here is using it as part of this project.

Mia: That’s very cool. Segueing into the next question, what do you do for work?

Brian: I used to work for Valeo vision systems and that’s how Norman [Koren], Henry [Koren], and the team would know me. I was working in automotive image quality, so everything from simple backup cameras to surround view cameras, mirror replacement cameras, cameras for autonomous driving; everything to do with that. In my career I was primarily responsible for, I suppose, image quality, assessment tuning and optimization. So, everything from measuring the sharpness and noise performance of the cameras to trying to get the best image quality for reviewing, machine vision, and performance; that kind of thing.

Mia: What feature in the software do you find yourself using the most or kind of what’s been your favorite feature, if that’s the avenue you want to take it in?

Brian: Yeah, sure. The most common ones that I’ve used would have been the SFR test for measuring the sharpness of the cameras. I’ve used that quite a bit. The step chart tools for measuring color accuracy with the color checker charts as well. I’ve also used the uniformity measurement quite a bit for measuring the color and shading uniformity of lenses. So, those that have been the ones that I’ve used most commonly. There are other ones I’ve used as well for measuring aliasing using the wedge targets, and I use some of the newer ones for the ISO-16505 standard. I do use some of the dynamic range measurements and some of the CPIQ measurements–less often, but I do use those too.

Mia: Well that’s very cool. It seems like you got to cover a lot of the software.

Brian: Yeah. I know that you mentioned features that that I liked: I like the chart order feature. So obviously yours is everywhere, Imatest manufacturers test targets. But every now and again it’s nice to just print off a chart, quick and dirty, for doing quick tests. The chart order function has proved very useful over the years. Another one that’s nice—it’s basically an image quality simulator where you can simulate different MTF curves for illustration and demonstration purposes.

Mia: Cool, thank you. Being that you’re in the image quality industry directly, is there any direction you’d kind of like to see Imatest go?

Brian: Not particularly as such. In terms of image quality assessment, there’s only a handful of companies that are involved, and Imatest is one of the leaders in the area. I’ve given feedback over the years as time has gone by. But you know, a team like Norman and Henry, and even Paul Romanczyk, they go to the standards meetings and are heavily involved. Whatever is going on in the industry, Imatest has had people that are either at the conferences or involved with the standards. So I think in terms of the developments that are going on in the industry, it’s safe to say Imatest has a reasonable, good finger on the pulse from that point of view. In terms of features and stuff like that, I suppose a couple of years ago I would have said that Imatest weren’t as good as some of the competitors in terms of some of the hardware, Imatest was more refined for targets and software. However, that gap has closed in the last few years.

 

Thank you to Brian for his valuable feedback and participation!

Veiling glare and Dynamic Range measurement from two images Presentation

Stray light (veiling glare) degrades image quality by fogging important details in darker areas, but it can be challenging to measure.

Imatest founder and CTO Norman Koren presents a technique that uses two images of the Contrast Resolution chart, taken without and with a mask, to obtain:

• A measurement of veiling glare
• insight into its effect on camera performance, especially the visibility of objects in darker areas
• two DR measurements
