Using Arbitrary Charts for Development of the P1858 Variation Combo Chart
The release of Imatest 5.0 introduced a number of powerful new features, including the Arbitrary Charts module which enables Imatest analysis of test chart designs which would be otherwise unsupported by the software. This new module allows user-defined chart layouts for any situation which requires one. (more…)
Five reasons to use Imatest 5.0
This week, we launched Imatest 5.0. We built Imatest 5.0 to provide users with a streamlined workflow for more efficient image quality analysis. Here are five reasons to start using Imatest 5.0 today.
Imatest IS Discontinued with Image Acquisition now Available in Imatest Master
As of Imatest 5.0, Imatest Master now features image acquisition capabilities. Previously, image acquisition capabilities were supported by Imatest IS, which has been discontinued as a separate product. This provides all of our customers with access to the acquisition library. The library supports direct acquisition from a wide range of frame grabbers and cameras, as well as industry standard interfaces. Direct image acquisition cuts out several steps in the image quality testing process and allows for in-the-loop testing with Imatest.
Closing the Loop: Distortion Correction
Imatest’s charts and software allow you to measure the characteristics and parameters of imaging systems. Quite often these measurements simply indicate the limits of system performance and expected image quality.
But some Imatest results let you improve image quality— and subsequent images taken by the same system— by correcting measured aberrations. (more…)
Best practices for using transmissive test charts
Light Source
The most uniform light source available would be an integrating sphere, but these come with considerable size and expense. After considering how the light source uniformity impacts their results, most lab & manufacturing tests use LED or fluorescent lightboxes with flat-panel diffusers. (more…)
Testing a macro lens using Checkerboard and Micro Multi-slide
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.
Using Sharpness to Measure Your Autofocus Consistency
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…)
Introducing Imatest 4.5
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.

The Operator Console: Open Source GUI for Imatest IT
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 and Sofica Partner for Automated R&D Testing
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 Version 4.4
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.
Auto-focus, Auto White Balance, and Auto Exposure (AAA) metrics for faster image adjustments. AAA metrics were created to address the video image quality aspects that most affect user experience.
Imatest 4.3
We are pleased to announce Imatest 4.3. New features include:
-
- Support for Linux (Ubuntu 14.04) across all Imatest software
- Python API for IT for a simplified, flexible development environment
- SSIM module for estimating the loss of image quality caused by image processing, especially data compression
Transmissive Color Targets
This new 24-patch Transmissive Color target can be used for evaluating color accuracy using a lightbox, which can be more compact and uniform than a reflective lighting system.
These targets are produced with high-precision Light-Valve Technology. (more…)
Automated Manufacturing Test Equipment
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.
Sinusoidal Siemens Star Target
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…)
SFRreg Target
High Dynamic Range Target, ITI LED Lightbox
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…)
Imatest version 4.2
Imatest has released Version 4.2. New features include:
SFRreg Module: Analyze a camera’s Spatial Frequency Response (sharpness) using automatically-detected slanted edges in registration mark patterns, which can be arbitrarily placed in a camera’s field of view. (more…)
