What are the specific performances and differences of backlight compensation, strong light suppression and wide motion in cameras? thank you

Backlight compensation: when the person's back is facing the light, the facial image is very tight. Backlight compensation can adjust and enhance the brightness of face image to some extent, and improve the image effect;

Strong light suppression: when the headlights of the vehicle are turned on at night, the camera is overexposed and the picture is all white. Strong light suppression can shield the strong light source in the picture and make the whole picture achieve better results.

Wide dynamic: Generally, there is an optimal illumination range for camera imaging, beyond which the imaging effect will be poor, while the camera with wide dynamic function has a larger range.
