The Contrast Chart is specifically designed to meet the requirements of the IEEE P2020 standard for automotive imaging systems. It enables accurate and repeatable measurements of Contrast Transfer Accuracy (CTA) (formerly known as Contrast Detection Probability (CDP)) and Contrast Signal-to-Noise Ratio (CSNR) across the image field under controlled laboratory conditions.
Engineered for high precision and durability, this chart is ideal for R&D teams and automotive camera manufacturers seeking to validate and benchmark ADAS and in-cabin imaging performance in line with industry standards.
General specifications:
- Size: 960 x 640 x 117 mm
- 3 slides of 310 x 310 mm
- Material: Aluminum & PVC
- Reference: CPI_0001
Measurement descriptions
These two contrast performance indicators assess a camera system’s ability to detect and differentiate between varying levels of contrast. The metrics ensure that the device can distinguish contrast at any luminance level and under various intensity and contrast conditions, ultimately generating a performance curve.
Contrast Transfer Accuracy (CTA):
It measures how faithfully the contrast between a pair of patches in the captured image matches the reference scene. It quantifies the system’s ability to preserve contrast accurately. A CTA value close to 1 indicates a high level of fidelity to the original scene contrast.
Contrast Signal-to-Noise Ratio (CSNR):
It evaluates the system’s ability to detect contrast in the presence of noise. It reflects how well the camera can distinguish between two patches despite noise. A higher CSNR indicates a stronger signal relative to noise, meaning the contrast is more clearly perceived by the camera.
