The Master Edition is Imatest’s most popular product and is used by hundreds of companies, worldwide. The Master Edition supports all visible light image quality tests, including sharpness, color accuracy, noise, lateral chromatic aberration, dynamic range, uniformity, ISO sensitivity, distortion, and more.
The Master Edition is widely used across the digital imaging industry in R&D, acceptance testing, quality control, camera assembly, and standards specification.
TYPICAL DEVICES TESTED
Visible-light digital imaging devices are tested using the Master Edition, including webcams, camera-phones, point-and-shoot cameras, DSLRs, scanners, camcorders, cinematography cameras, security cameras, automotive imaging systems, video gaming systems, video conferencing systems, medical imaging systems, and telescopes.

FEATURES & SPECIFICATIONS
SFRplus, when used in combination with the SFRplus test chart, offers fully automated region-of-interest detection and can be used to measure MTF, lateral chromatic aberration, distortion, tonal response, and color.
SFR measures the sharpness, noise and chromatic aberration of cameras and lenses using a simple slanted-edge target. It allows users to compare digital cameras on an objectively fair basis. It can analyze regions as small as 10×10 pixels.
Stepchart measures a camera’s tonal response, noise, and dynamic range using grayscale step charts. It also measures exposure accuracy and veiling glare (lens flare) with reflection step charts.
Colorcheck measures a camera’s color quality, tonal response, exposure accuracy, and noise using the GretagMacbeth ColorChecker.
Multicharts analyzes several color charts for tonal response and color accuracy using a highly interactive interface. It also analyzes grayscale charts for tonal response.
Distortion measures lens distortion and calculates coefficients for correcting it using a square or rectangular grid that can be printed from files created by the Test Charts module.
Uniformity measures the light falloff throughout the image due to factors such as lens vignetting and field dependent f/# variation. It measures several types of image sensor nonuniformity, including color shading, detailed noise distribution, and medium-sized (visible) nonuniformities, inculding dust smudges. It also flags stuck (dead and hot) pixels. Display options include contours superposed over images and pseudocolor with color bar.
- Print Test:
Print Test measures the quality (color response, color gamut, tonal response, and Dmax) of printers, inks, paper, ICC profiles, and rendering intents.
