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 you to compare digital cameras on a fair basis. It can analyze regions as small as 10x10 pixels. |
MTF Compare uses the results of SFR to compares the MTF of different cameras, lenses, and imaging systems. |
Rescharts analyzes several resolution-related test charts using a highly interactive interface. Functions include Slanted-edge SFR, which Log frequency, which measures MTF and color moire. |
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 (vignetting) of lenses. 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. |
Test Charts creates image files for printing test charts on high quality inkjet printers. Charts include SFR slanted-edge images, star charts, patterns with varying spatial frequency and contrast, and zone plates. Options include: contrast ratio, highlight color, and sine or bar pattern. Outputs are Bitmap images and Scalable Vector Graphics (SVG). |
Print Test measures the quality (color response, color gamut, tonal response, and Dmax) of printers, inks, paper, ICC profiles, and rendering intents. |
