CP316

Black & White Dead Leaves Test Chart

The CP316 chart is designed to evaluate the loss of mid-to-low contrast and texture details in imaging devices caused by noise reduction or other image processing techniques. The chart consists of 5 elements: a gray background, positioning markers, grayscale patches, slanted edges, and a central dead leaves pattern. For optimal performance, it is recommended to use the chart together with Yanding’s RIQA Image Quality Analysis Software.

Quick Specifications

Multi-dimensional texture analysis: 16 grayscale blocks are used for linearization calibration
‌Dual MTF verification‌: 4 slanted edges synchronously compare texture and edge MTF data
‌High-precision positioning‌: Fiducial marks ensure repeatable test area alignment
Graphic Size:400×533mm,Chart Size:500×600mm
Supported by RIQA Camera Image Evaluation Software
