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…)

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.

Imatest is proud to announce a new partnership with Edmund Optics. You can visit Edmund Optics Silicon Valley Solutions Center in Cupertino California. This is a facility where you can integrate machine vision cameras from Allied Vision and Teledyne with Edmund Optics lenses and test them on an Imatest test fixture. EO’s application engineers can consult with you about designing the optimal lens for your imaging task.
Imatest Version 22.1 introduces new features including Automatic Chart Identification, Internationalization, ISO 12233 Standards Support, Sagittal/Tangential MTF Plot Updates, and more. (more…)

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…)
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.
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.
Imatest Version 2021.2 introduces our new Main Window User Interface, File First Workflow, Dark Mode, a new ‘Learn’ Function, Distortion Contour Plots for Checkerboard Output, new JSON output fields, and more. (more…)
