HDR multi-function light box

The human eye can perceive a wide dynamic range (100dB), and effortlessly observe bright and dark scenes at the same time, which is difficult for ordinary Sensors to achieve in one exposure. Generally, under strong light or backlighting and other relatively low brightness conditions, the camera image will appear particularly bright or particularly dark. The bright area is due to overexposure, and the dark area is due to underexposure, which seriously affects the image quality.

Sports cameras, security cameras or automotive cameras have strong and weak light contrast and motion scene capture in the actual application environment, so pay more attention to the imaging quality of their cameras in wide dynamic scenes, usually collecting high dynamic (high light ratio) static outdoors Or sports scenes, to judge whether the camera produces motion artifacts, how sharp or lost details, etc.~

Based on the test requirements of high dynamic scenes, how to achieve a high dynamic scene of 0～120dB that can be simulated outdoors in the laboratory?

HDR multifunctional light box

The HDR multifunctional light box is used to test the motion imaging effect of the camera in the HDR environment, evaluate the recognition effect of the camera on the HDR scene, and realize the simulation of a wide dynamic range (0～120dB). The equipment includes a light source control system, a motion system and an ambient light feedback system.

The whole system is divided into two parts: the strong light system and the low light system, separated by an 18% gray light barrier in the middle. Each side has a separate controllable lighting system, which supports test cards for linear motion and rotary motion.

The light box is equipped with an illuminance color temperature sensor, which can automatically adjust the color temperature and illuminance on both sides in a closed loop. It can not only test the wide dynamic effect of the camera, the contrast effect under different color temperature illuminance, but also test and observe the screen of the mobile phone or tablet computer, and adaptively adjust the effect of color and contrast under the condition of external color temperature and illuminance changes. Many different test items can be integrated.
