We are happy to announce that Imatest Master 3.10-Beta is now available for Mac OS X
We are confident in the stability of the image quality testing algorithms in this version, but have kept the Beta tag on this release since there may be some minor issues that remain to be resolved before we remove the Beta tag. (more…)
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 3.9 was released on December 14th 2012. Please contact sales@imatest.com for purchase or renewal information.
Here is a complete list of changes:
Imatest main window: Explore image file folder and Explore recent save folder have been added to the File dropdown. INI File Settings have been given their own dropdown to minimize clutter. Explore INI file folder has been added. The INI file Editor (useful for fixing errors and for setting up INI files for the Functional Interface and IT) has been greatly enhanced. (more…)
Imatest 3.8 was released on May 14th 2011. Please contact sales@imatest.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
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
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
Release 3.2 of Imatsest Master includes SFRplus, a new capability that automatically identifies regions of interest (ROI) and helps you rapidly complete a wide range of image quality tests, including sharpness, lateral chromatic aberration, lens distortion, gamma (contrast), and tonal response. (more…)
Multiple files can be read and averaged (and saved) to facilitate measurements of fixed-pattern noise (in Stepchart, Colorcheck, and Light Falloff) and image stabilization (SFR). Highly distorted regions of interest (ROIs) can be analyzed with Colorcheck and Stepchart. New ΔE measurements and hot/dead pixel options have been added to Light Falloff.
Imatest Master and Studio have been introduced, replacing Pro and Light. Support for Bayer RAW images has been strengthened.
The new Dynamic Range module calculates dynamic range from Several Stepchart images of reflective targets (much easier than using transmission targets).
The Screen Patterns module displays several patterns for Imatest modules, monitor calibration, and camera testing.
Spot detection is now available in Light Falloff. CIEDE2000 color difference metrics are now available in Multicharts and Colorcheck.
Two new options are available for refining multiple ROI selections in repeated SFR runs (Imatest Master only). (1) Multi-ROI fine adjustment (shift, magnify, reduce), and (2) Automatic ROI refinement. These speed up test sequences of different cameras and lenses, where it may be difficult to maintain exact chart alignment.
RAW files are supported for a large number of digital cameras using Dave Coffin’s dcraw program. Files are converted with minimal signal processing— no sharpening or noise reduction. This allows the true performance of cameras and the behavior of raw converters to be analyzed.
Chromatic Aberration is now measured as percentage of the distance from the image center. This is an improvement over area in pixels because CA tends to be proportional to that distance. (more…)
Greatly expands noise and dynamic range calculations in Q-13 Stepchart and noise calculations in Colorcheck. Noise measurements in f-stops have been added to both programs. These are relative measurements, which correspond closely to the workings of the eye. Q-13 Stepchart now calculates total dynamic range (using a more sensitive detection algorithm) as well as noise-limited dynamic ranges for several quality levels. Colorcheck now includes noise measurements for the third Colorchecker row, which includes Blue, Green, Red, Yellow, Magenta, and Cyan.
In evaluation mode, multiple region SFR runs now count as two runs (even if more than two regions are selected).

September 3, 2004 -Imatest LLC announces the release of Imatest 1.0, a software package that measures the sharpness and image quality of digital camera images and digitized film images using inexpensive widely-available targets. Never before has it been possible for photographers to measure the performance of their cameras and lenses with such accuracy and convenience. You had to rely on subjective judgments or published test results. Now you can perform your own measurements, simply and easily, by photographing a target and analyzing the results with Imatest software. (more…)
