The CP197-TI V2 chart adopts a transmissive structure consisting of 36 grayscale patches, 4 background patches, and 4 markers. The grayscale patches are arranged in a circular layout to maintain high uniformity during imaging. Unlike conventional charts, CP197-TI integrates a polarizer at the center, providing a novel solution for devices lacking manual exposure adjustment, thereby significantly enhancing testing flexibility.
Its grayscale distribution complies with ISO 14524 and ISO 15739 standards, and the density of grayscale steps has been carefully optimized, ensuring more accurate dynamic range measurements. The chart achieves an exceptional contrast ratio of 30,000,000:1 (approx. 150 dB), meeting the needs of ultra-high dynamic range imaging systems. At the same time, it delivers stable manufacturing quality and excellent neutrality.
For use, the transmissive chart requires uniform illumination. Pairing it with Yanding's high-brightness transmissive lightbox is recommended to guarantee consistent lighting. In combination with RIQA Camera Image Quality Analysis Software, it allows precise measurement of OECF, dynamic range, SNR, noise.
