HDR Transmissive Charts Setup
HDR Transmissive Charts with dedicated LED Panels
As HDR is increasingly used in photographic, video surveillance, and ADAS devices (among other applications), brands and manufacturers must assess their HDR performance and tune them accordingly. Analyzer’s HDR Module includes a Composite chart with automated and controllable lighting so you can measure essential HDR attributes such as color, texture, and contrast in one shot. It also contains a Natural Scene chart for perceptual analysis to complement Composition chart measurements and an HDR Noise chart for dynamic range and noise analysis.
Key Highlights
● Tone mapping
● Dynamic and tonal range
● Signal-to-noise ratio
● Dark signal
● Tone curve
● ISO Sensitivity
● Texture preservation
● Contrast preservation
● Color consistency
● Artifact analysis: texture loss, moiré, aliasing, color shift

HDR Tone Mapping – Composite charts
This setup is composed of two Gemini with their Composite charts. The composite chart contains three main patterns — grayscale, 24-color matrix, and dead leaves. The setup lets you verify your camera’s ability to consistently reproduce colors, manage noise, and preserve contrast and texture in comparison with an objective reference. Using recommended lighting, you can simulate a dynamic range of up to 15 EV in the test scene.

HDR Tone Mapping – Natural Scene charts
This setup is composed of two Gemini with their Natural Scene charts. This detailed real-life scene is used for
performing lab-based perceptual analyses under controllable HDR conditions.
It also facilitates evaluation of texture loss, moiré, aliasing, color shift, and sharpness.
