Imatest Version 2021.1 adds several new features to Imatest Master and Imatest IT, including edge tracking during live focusing, alignment tools in device manager, new subjective exposure quality loss calculation, OpenEXR support, live exposure and white balance measurements and several customer-requested features.

Edge tracking during live focusing in Imatest Master

Improved performance and stability when adjusting focus during live image acquisition. This enables refinement of your regions of interest as focus or distance adjustments impact your camera's magnification and cause your regions of interest to shift. When displaying more than one region, shifts of the position of the target within the image can be tracked.

Improved Display Alignment for Device Manager

Provides enhanced user capabilities for aligning test charts including crosshairs and grid line display. Use the Device Manager to select and configure your device and align your test charts for use with Live Image Acquisition or Focus Score Plus features.

Rescharts Focus Score Plus

Enables real-time auto WB, focus, and exposure measurements on any image region. Users can view metrics such as Sharpness or Color Temperature change in real time as live focus or lighting conditions are adjusted.

OpenEXR HDR format support

Imatest now supports reading OpenEXR images. Customers can use this format with enhanced high dynamic range and color precision.

LibRaw Next Generation RAW decoder

The successor to dcraw offers additional camera support and allows users to read files such as Canon CR3. Libraw supports a total of 1052 cameras, adding support for 321 new cameras compared to what was previously provided with dcraw.

CPIQ v2 Exposure Quality Loss Calculation

Calculation of Exposure Metric which determines the effect of over or underexposure on perceptual quality. Available on Colorchecker-24 and Colorchecker-SG charts through the Color/Tone module. The metric is reported using units of Just Noticeable Differences (JND).
