The release of version 3.10 of Imatest brings a host of improvements to make image quality testing faster and more relevant to advances in cameras. Look for performance, stability, interface and measurement improvements across the board as well as some excellent new modules and features. (more…)
Imatest currently sells several transmissive (backlit) test charts, which have a range of substrates, each with specific properties and qualities that are in process of being quantified. The following comparison of the most important of our transmissive substrates was prepared in response to several customer inquiries.
Using Babelcolor Patch Tool or SpectraShop 4
This post describes how to measure color and grayscale patches on a variety of test charts, including Imatest SFRplus and eSFR ISO charts, the X-Rite Colorchecker, ISO-15729, ISO-14524, ChromaDuMonde CDM-28R, and many more, using a spectrophotometer and one of two software packages.
- Babelcolor PatchTool which works with reflective test charts
- Robin Myers SpectraShop 4 which works with both reflective and transmissive (backlit) test charts

Imatest 3.8 was released on May 14th 2011. Please contact email@example.com for purchase or renewal information.
Here is a complete list of changes:
I3A CPIQ (Camera Phone Image Quality) enhancements: The Dot Pattern module has been added for analyzing distortion and lateral chromatic aberration (LCA). The Dot pattern and ISO-15739 charts have been added to Test Charts. The CPIQ Acutance measurement (similar to SQF) has been added to SFR and SFRplus. The CPIQ color uniformity metric (ΔCmax) has been added to Light Falloff and Uniformity Interactive.
Noise analysis has been added to Multicharts. Support for extremely distorted SFRplus charts has been improved.
Changes released in other versions are available on our Changelog
For measurement of sharpness, the main driver of variation is noise. A powerful noise reduction technique called modified apodization is available for slanted-edge measurements (SFR, SFRplus, eSFR ISO and SFRreg). This technique makes virtually no difference in low-noise images, but it can significantly improve measurement accuracy for noisy images, especially at high spatial frequencies (f > Nyquist/2). It is applied when the MTF noise reduction (modified apodization) checkbox is checked in the SFR input dialog box or the SFRplus or eSFR ISO More settings window. (more…)
New infrared test charts and analysis software modernize testing of infrared cameras
Once viewed as exotic devices, infrared camera systems have moved into the mainstream in many industries, particularly in security and defense. From night-vision helmets, scopes, and security cameras to ballistic missile tracking telescopes, IR cameras have become as commonplace as they are mission-critical. As with other advanced technologies, quality control is key to successful development and application of IR camera systems, with the quality of the image itself being paramount to most organizations.

Toshiba America Electronic Components, Inc. (TAEC), a committed leader that collaborates with technology companies to create breakthrough designs, and Imatest LLC, maker of the world’s most popular image quality testing software, have teamed up to enhance Imatest’s Image Sensor (IS) Edition, a highly anticipated and powerful tool to help engineers responsible for configuring Toshiba image sensors.
Version 3.6 of Imatest’s Master Edition delivers sophisticated blemish detection capabilities based on the human visual system’s ability to detect blemishes. Soon this feature will also be added to the Industrial Testing Edition to enable blemish detection in high-volume camera-system production. Details here
Imatest has expanded its capabilities and staffing to better meet customer demand for consulting services. Now offering skills and experience in imaging science, optics, image quality testing, camera system design, software development, and project management, Imatest looks to play an increasing role in helping customers deliver leading-edge imaging systems. Details here
ISO sensitivity (also called ISO speed), is included in Release 3.5 of both Imatest Master and Industrial Testing (IT) packages. ISO sensitivity is a measure of how strongly an image sensor and/or camera responds to light. Both Saturation-based and Standard Output Sensitivity, as described in ISO 12232, are calculated, but the measurement procedure has been considerably streamlined as compared to the ISO specification. (more…)
Version 3.4.1 of Imatest Master, IT, and IS is now available and includes optimizations to SFR and SFRPlus that drastically reduce processing time for computing MTF (sharpness). Depending on options and settings, results are delivered in half the time or better. Download the latest version today: www.imatest.com/download
- 3D plots with automatic or manual scaling are available in SFRplus and Light Falloff. These plots can be rotated for improved visualization and offer numerous display options. 3D Fig files should be used sparingly: they’re much larger than PNG image files.
- A second secondary readout is available in SFR and SFRplus.
Boulder, Colo. — Imatest LLC, the leading provider of digital image quality testing software, and The Center For Artificial Vision (C4AV; www.C4AV.com), in Novi., Mich., the leading digital camera module supplier in North America, have partnered to expand distribution and support for the recently released DevWare Edition of Imatest, a software package that enables rapid, automatic testing of image quality during the process of configuring ON Semi image sensors (www.onsemi.com), an image sensors company based in San Jose, Calif.
