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…)
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…)
Introducing the CM10120 Collimator – a target projection collimator system that allows users to simulate long-range testing in confined spaces. This compact solution can be used for regional sharpness testing, making it useful for tasks such as setting focus or checking pass/fail criteria. The CM10120 includes adjustable distance simulation and is suitable for R&D, production, and end of line testing. To learn more about the CM10120, contact us at sales@imatest.com.
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.
Imatest is excited to announce a new subscription option for all of our software products. Beginning June 1, 2021, Imatest customers will be able to purchase an annual subscription to our Imatest Master, IT and Ultimate software for both node-locked and floating licenses.
Imatest, LLC, a leader in image quality evaluation tools, today announced the launch of their new Camera Geometric Calibration Validation service to provide objective metrics for calibration quality. The Service uses upcoming IEEE P2020 geometric calibration standard as a reference. (more…)
