- 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).
- Random Pattern (Noise) Test Chart The Imatest Random Pattern chart is a variant of the Dead Leaves chart designed to measure texture sharpness.The Random pattern is the extreme pattern for noise reduction: it maximizes noise reduction while minimizing sharpening, improving the accuracy and robustness of measurements. In addition, gray regions to the left and right of the chart 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).
- Log Frequency Contrast Chart The Log-F contrast chart is analyzed by Imatest Rescharts.
- New Dynamic Range Test Charts These targets have 36 low-noise density patches and density ranges exceeding 50dB, 100dB and 150dB. The three options fulfill needs for Low, Wide, and Ultra-High Dynamic Range systems. A nearly circular patch arrangement ensures that vignetting has minimal effect on results. For the Wide and Ultra-High variants, there are regions on the left and right sides of the chart for detecting flare light that can interfere with HDR performance.
- 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.
- Imatest DarkWorld Mask and Frame The DarkWorld mask pairs with the the Imatest 36 patch Dynamic Range Test Charts and Frame to block additional light from entering the camera. The additional light included in the non-measurement areas of the standard “GrayWorld” targets (LDR/WDR/UHDR) is intended to allow the camera under test to get a good automatic exposure on a scene that somewhat resembles a real world scene where flare light is present inside the lens.
