What is "imatest"

Imatest LLC is a company that produces image quality testing software and offers a range of consulting services. Imatest was founded by photographer/ engineer Norman Koren in Boulder, Colorado in 2004 to develop software for testing digital camera image quality.

Using Imatest software, a variety of image quality factors can be analyzed including image sharpness, color response, noise, dynamic range, tonal response, lens flare, lens distortion, lens vignetting, sensor non-uniformity, and color moiré.

Imatest has been adopted by a wide range of industries that employ embedded digital imaging systems, including mobile imaging (camera phones), medical imaging, aerospace and machine vision, as well as publications/reviews, and academic, cultural, and research institutions. Imatest software is referenced in research, art, and industry.

Among many other applications, Imatest has been used to adjust images with different amounts of sharpening to a standard amount of sharpening, and to compare resolution in of those adjusted images. Imatest also tests color accuracy, tone-scale linearity, image distortion, light falloff, and printing gamut.
