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 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…)

Correlating the Performance of Computer Vision Algorithms with Objective Image Quality Metrics

by Henry Koren

1. Why care about the quality of your cameras?

The task of computer vision (CV) involves analyzing a stream of images from an imaging device. Some simple applications such as object counting may be less dependent on good camera quality. But for more advanced CV applications where there is limited control of lighting & distance, the quality of your overall vision system will depend on the quality of your camera system. This is increasingly important when an error made by the vision system could lead to a decision that impacts safety. Along with proper optimization of a CV model, ensuring that that model is fed by imagery from a high-quality camera system is critical to maximizing your system’s performance.

Google’s Android Image Quality Expert Pursues New Role With Imatest

Imatest is happy to welcome Jonathan Phillips, previous Google Android head of imaging, to the team as Vice President of Imaging. Under Phillips’ technical leadership, Imatest will be expanding its software features, equipment portfolio, and consulting services across imaging market segments. As the previous leader of image quality in Google’s Android organization, Phillips focused on the launch and establishment of Google’s Pixel phone line, particularly its camera and display image quality and features. In addition, Jonathan has an extensive background in image quality with NVIDIA and Kodak, and is a co-author of “Camera Image Quality Benchmarking”. (more…)

Logarithmic wedges: a superior design

We introduce the logarithmic wedge pattern, which has several advantages over the widely-used hyperbolic wedges found in ISO 12233 (current and older) and eSFR ISO charts. Logarithmic wedges will be available in eSFR ISO charts starting in 2022, and will be supported by Imatest 2021.2+.

The key advantage of logarithmic wedges is that charts with large fmax/fmin ratios work well for systems with a wide range of resolutions, unlike hyperbolic wedges, where large ratios cause high frequencies occupy excessive real estate and low frequencies to become highly compressed. The fmax/fmin ratio of the hyperbolic wedges in the ISO 12233/2017 chart is only 12.5:1 — insufficient for modern high resolution cameras.

Camera to Chart Alignment

Centering test charts is critical for image quality testing. If the camera is not properly aligned with the test chart, your image may not be suitable for analysis; you may not know if the results are truly indicative of the camera system, or from an error in positioning the chart.  (more…)

Using images of noise to estimate image processing behavior for image quality evaluation

In the 2021 Electronic Imaging conference (held virtually) we presented a paper that introduced the concept of the noise image, based on the understanding that since noise varies over the image surface, noise itself forms an image, and hence can be measured anywhere, not just in flat patches.

You can download the full paper (in the original PDF format) here.
