We are pleased to announce our new High Dynamic Range (HDR) test chart with a density range exceeding 120dB (optical […]

Starting with Imatest 4.2, Imatest’s two-dimensional color displays— CIELAB a*b*, CIE 1931 xy chromaticity, etc.— in Multicharts, Multitest, Colorcheck, SFRplus, and eSFR ISO can display ellipses that assist in visualizing perceptual color differences. You can select between MacAdam ellipses (of historical interest), or ellipses for ΔCab (familiar but not accurate), ΔC94, and ΔC00 (recommended).

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 […]

Imatest version 4.2 is now available as a public beta. Join our Beta Test Group to access 4.2 updates. Highlights include:

• SFRreg Module: Analyze the SFR of slanted edges through the automatic
   

  detection of registration mark patterns (circles with two light and two dark quadrants). Use arrays of registration mark targets to test unique imaging systems, including systems with ultra wide angle fisheye lenses (>180 degrees), multiple camera combinations, video and more.

 

• Point Spread Function (PSF): Imatest can now estimate an imaging system’s loss of resolution (PSF)
   using a pair of collocated, near-sagittal and tangential slanted edges on SFRplus, eSFR ISO and SFRreg targets. Easily analyze and improve sharpness, chromatic aberration, and distortion measurements.
