IMC145 measures imaging-system SNR and dynamic range under ISO14524 and ISO15739,with multiple regions for cameras,lenses and sensors. The source recommends a Yanding standard transmission HDR lightbox for efficient,precise testing. Five modules:1. Peripheral location marks support automatic software analysis/alignment.2.36 central annular grayscale steps reduce vignetting effects on SNR/dynamic-range results for accuracy/consistency.3. Central/side color patches evaluate reproduction/accuracy.4. Side square matrices assess stray-light effects on HDR.5. Peripheral slanted edges support resolution testing/analysis.

High-precision dynamic-range testing: a circular grayscale layout with 150dB dynamic range ensures uniform measurement across luminance intervals. Comprehensive image-quality assessment integrates color, stray-light and resolution tests. Strict ISO compliance supports authoritative results. Five functional regions: positioning marks, circular grayscale, color patches, stray-light detection matrix and resolution slanted edges. 36 ring-arranged grayscale patches reduce vignetting interference and improve dynamic-range test accuracy. Supports color reproduction, HDR interference resistance and resolution verification.
