Wide Dynamic Features
- Apr 07, 2018 -

When a high-luminance area under shadow light irradiation and shadows, areas with relatively low relative brightness such as backlighting exist in the image at the same time, the image output by the camera will cause the bright area to become white due to overexposure, and the dark area becomes black due to underexposure , seriously affecting image quality. Wide dynamics is the technique applied to make particularly bright parts and particularly dark parts of the scene visible at the same time. Wide dynamics exposes two times at the same time, one at a time and one at a slow time. The synthesis is then performed so that bright and dark objects on the screen can be seen at the same time. The wide dynamic technology application scene is similar to the backlight compensation. The wide dynamic technology uses two exposures of the sensor to obtain two images that can be seen in the foreground and the background, and then performs image superposition. The wide dynamic is not suitable for the scene of fast moving objects.
