Autofocus plays a major role in many camera system applications with variable focus, including consumer electronic devices. Camera systems must be able to focus at a variety of distances. Optical systems on cameras only allow a certain range of distances from the camera to be in focus at once (this is often known as the depth of field, or depth of focus). (more…)
Imatest’s Checkerboard module is our new flagship module for automated analysis of sharpness, distortion and chromatic aberration from a checkerboard (AKA chessboard) pattern. The big benefit of using the checkerboard is that there are looser framing requirements than with other kinds of test targets. While checkerboard lacks the color and tone analysis provided by SFRplus and eSFR ISO, these features are not available on the high precision chrome on glass substrate, so the checkerboard is the optimal pattern for this test.
Imatest 4.5 is the most powerful version of the platform yet with enhancements and additions for a variety of industries, including automotive, medical, consumer electronics, security, and more. The newest features give users increased flexibility in the range of target distances and light levels to improve your high-speed, automated testing.

Update: Starting in Imatest 4.5, a pre-built, ready-to-run version of the Operator Console now ships with all Imatest IT Windows installations, allowing users to take advantage of the simplicity of the Operator Console without writing a single line of code. It can be found in the /samples/OperatorConsole directory.
Imatest is pleased to announce their partnership with Sofica, a group of camera algorithm validation and test automation experts based in Finland. This partnership will bring mobile device customers a revolutionary, robot-aided R&D test automation system integrated with Imatest analysis software and test charts.
Imatest is pleased to announce the release of version 4.4, which includes the following features:
Support for all 2016 Camera Phone Image Quality (CPIQ) standard metrics for mobile device image quality. CPIQ serves as a way to assess and communicate image quality to the vast majority of consumers who are unsure how to judge and compare device image quality. See a full CPIQ overview.
We are pleased to announce Imatest 4.3. New features include:
Imatest is pleased to announce our partnership with isMedia, a specialist in building digital imaging test machines and custom test solutions. This partnership will provide customers with a wide range of highly customizable test machines capable of extensive image quality analysis on manufacturing lines.
The Sinusoidal Siemens Star test chart allows you to measure MTF and limiting resolution with a chart that provides angular response and may be less affected by signal processing (especially sharpening) than slanted-edges. Siemens star MTF20 (the spatial frequency where MTF is 20% of its low frequency value) is a good estimate of limiting resolution. (more…)
We are pleased to announce our new High Dynamic Range (HDR) test chart with a density range exceeding 120dB (optical density >6.0). This chart allows you to the measure the dynamic range, tonal response and noise of HDR cameras with a single image instead of multiple, exposure bracketed images. It also contains slanted edges for MTF measurements. (more…)
New Photographic eSFR ISO
The ISO 12233:2014 Enhanced eSFR Photographic Target is our newest reflective test chart. Photographic prints have over twice the resolution of inkjet prints, making them more suitable for higher resolution camera systems like DSLRs. The photographic substrate will benefit customers interested in testing high-resolution sensors as well as those performing close-range macro tests. (more…)
New Feature: Imatest IT Parallel
The new Imatest Industrial Testing Parallel uses parallel processing to improve the throughput of Imatest IT and maximize the image processing power of your computing hardware. IT run in parallel enables up to 3x more throughput to support test equipment that requires a high volume of images to be analyzed. IT-P improves the PPH (parts per hour) on assembly lines.
Standard Imatest inkjet-printed test charts produced prior to February 2016 work in Near InfraRed (NIR) wavelengths out to approximately 1 micron.
In February 2016 we upgraded our printers and found (to our disappointment) that our new printers do not have the same reflective densities for NIR wavelengths as for visible wavelengths. We are working out solutions to this issue. Please contact us if your needs include NIR. (more…)
SFRplus and eSFR ISO share many similar features and can be used to perform many similar image quality analyses. However, some of their features differ, and understanding which features differ will help you select the most appropriate test chart to analyze your imaging systems. This video outlines key differences between SFRplus and eSFR ISO.
