170 dB Dynamic Range

This setup can saturate any sensor! (IEEE 2020 Compliant)

The image sensor sector is booming, especially in new markets such as autonomous cars. Such applications require higher performance — for example, a very high dynamic range. However, obtaining repeatable and rigorous measurements of these new capabilities is very complex.

The image sensor sector is experiencing significant growth, particularly in emerging markets such as autonomous vehicles. Such applications require higher performance, for example, a very high dynamic range. However, obtaining repeatable and rigorous measurements of these new capabilities is a complex process.

We at DXOMARK follow these improvements by participating in scientific committees such as IEEE and ISO. In close collaboration with the industry and the 2020 committee, we have developed a dynamic range measurement setup that can measure 150dB or higher in one frame, thus meeting the requirements of the standard.

Our 170dB setup consists of 4 light panels whose intensity and spectrum can be controlled separately. High-quality test patterns complement the light panels and allow for high-precision measurements. The brightest panel can reach 1.5 million cd/m², saturating all sensors currently on the market.

General specifications:

Size: 1200 x 1200 x 800 mm
Power supply: 100–240 V, 50–60Hz
Total maximum power: 1800 W
Reference: DRP2020_001

Measurement descriptions

Observed & real relative luminance:

To check lens limitations due to glare, this metric shows the sensor linear response compared to the true luminance of the chart.

Contrast-to-noise ratio (CNR):

CNR is computed on all successive patches in the image captured by the camera, and is compared with the limit under which the camera cannot see (0 dB).

Tonal contrast gain (TCG):

TCG measures the contrast fidelity. In the case of nonlinear images, this metric is a better indicator about the quality of contrast reproduction.
