Dot Pattern Test Chart For testing chromatic aberration and SMIA TV Distortion
Spilled Coins Cross Test Chart The updated Imatest Spilled Coins Cross test charts use cross-correlation calculation texture metrics to provide improved stability for images with nonlinear noise reduction. Users can now more accurately differentiate between noise and texture. Random/Dead Leaves Cross, which runs under the interactive Rescharts interface, measures SFR (Spatial Frequency Response) or MTF (Modulation Transfer Function) from random scale-invariant (or approximately scale-invariant) test charts, including “Dead Leaves” and “Spilled Coins” charts.
Color Spilled Coins (Dead Leaves) Test Chart The Color Imatest Spilled Coins chart is a variant of the Dead Leaves chart designed to measure texture sharpness. It has several advantages over older Dead Leaves charts, including nearly perfect scale-invariance, which improves the accuracy and robustness of measurements, and gray regions to the left and right of the chart that facilitate noise removal (using a technique where gray patch noise Power Spectral Density is subtracted from the signal + noise PSD of the central Spilled coins region).
Black & White Imatest Spilled Coins (Dead Leaves) Test Chart The Imatest Spilled Coins chart is a variant of the Dead Leaves chart designed to measure texture sharpness. It has several advantages over older Dead Leaves charts, including nearly perfect scale-invariance, which improves the accuracy and robustness of mesurements, and gray regions to the left and right of the chart that facilitate noise removal (using a technique where gray patch noise Power Spectral Density is subtracted from the signal + noise PSD of the central Spilled coins region).
Imatest Contrast Resolution Chart The Contrast Resolution Chart is useful for the visualization and measurement of contrast separations that are observable within patches that range from light to dark. This can be useful to see how observable objects are within different contexts that could be impacted by flare light and nonlinear signal processing.
Simplified ISO-15739 digital camera noise test chart This 15-patch grayscale step chart has 12 of the patches in a somewhat elliptical arrangement on the periphery and three in an inside row. The relatively large patches are especially good for measuring noise. Supported by the Imatest Stepchart, Multicharts, and Multitest modules. Printed on 12x18 inch (305x457 mm) luster inkjet media.
Xyla Dynamic Range Test Chart When selecting a camera, it\'s important to consider the dynamic range of your sensor. Ensure an accurately measured dyanmic range using the latest high dynamic range test system from DSC Labs - the Xyla. With its built-in light source, the Xyla has an opaque surround to reduce camera flare and discrete, numbered, spectrophotometrically neutral steps which can be viewed individually or in groups.
Frame for 8\\ This acrylic frame can be used to mount any of the 8\" x 10\" film charts including the new ITHDR36 target, as well as the ITDR36 targets.
