Imatest 5.2 Release Notes

New Features and Enhancements

ON Semiconductor DevwareX support for this advanced image sensor interface software, which replaces Devware. Support for the APbase image acquisition API.

Decompanding for the proper processing of piecewise linear (PWL) companded RAW files, which can extend sensor dynamic range by allowing different tonal curves for ranges of digital output values.

Contrast Detection Probability (CDP) from Contrast Resolution chart using low-contrast path triplets to calculate the draft IEEE P2020 metric. CDP is a metric for the distinguishability from two input light levels through an imaging system.

Improved Color/Tone Module Interfaces – Chart selection is clearer and more robust. 
     Color/Tone Setup is the new name for Multicharts (interactive).
     Color/Tone Auto is the new name for Multitest (fixed).

Hyperbolic Wedge and Siemens Star analyses are now supported in Arbitrary Charts.

Dynamic Range (DR) Output Resistance to Flare Light – We can now detect conditions where flare light causes exaggerated DR measurements and can remedy the misleading measurements by limiting the quality-based DR to the slope based DR, which is defined by the scene density where the patch pixel-level stops decreasing.

INI File Monitor produces detailed reference information about the effects of settings changes on the Imatest INI file.

Checkerboard Uniformity Calculations produce summaries of nonuniform illumination similar to those produced by SFRplus.

Image Statistics Mesh Plot produces a 3D view of spatial pixel-level information.

Minor Features

Find sharpest files plot to show focus score metric across multiple images.

Faster bilateral filtering in Image processing module. 

Image acquisition Improvements: FLIR camera interfaces, GenICam upgraded, performance improvement for the acquisition of RGB frames, Dalsa Driver Upgrade, ORCA-Flash4.0 camera upgrade

Chart MTF Suitability Display as part of the chart quality calculator, this shows the quality level relative to sensor size and vertical field of view.

Debug Levels offer the ability to control the production error, warning, info, and debug messages.

Bayer Frequency Units previously when we would analyze a bayer RAW format we would do 4:1 downsampling while retaining the same pixel size. A new option in more settings enables cycles per total pixels or channel pixels to be selected.

Dcraw Updated to Version 9.28 that adds support for Canon EOS 5D Mark IV.

Improve Handling of High Bit Depth RAW and HDR Files by improving the lightening feature during region selection. 

Edge Spread Function Plots respect the selected spatial frequency units, previously it would always be in cycles/pixel.

Removed or deprecated items

Print Test been deprecated.

XML output deprecated; use JSON instead.

Geometric Calibration has been removed from Master and IT. This tool available in the 5.1 release is reserved for customers of Imatest’s total HW+SW solution. Contact us for details.

Distortion button shrunk and will be deprecated in a future release. 

Colorcheck and Stepchart will receive no future enhancements and will be deprecated in a future release. (Color/Tone Setup and Color/Tone Auto are recommended for all new work, apart from bug fixes.)

Multicharts and Multitest were renamed to Color/Tone Setup and Color/Tone Auto.

Autofocus consistency is deprecated; it remains available in 4.5-5.
