Abstract
A method for calculating a current illumination level of a target scene capable of quantitatively evaluating an illumination level in a scene through a camera, and a method for automatically adjusting an illumination level of the target scene capable of automatically performing a constant light control over a scene, and a camera, capable of quantitatively evaluating the illumination level in the scene and a smart illumination control system are provided. The smart illumination control system is capable of quantitatively evaluating the illumination level in the scene and automatically adjusting an illumination brightness, a color temperature, a color or a contrast in the scene to realize a constant control over a light environment. In addition, by setting the illumination level on a setting terminal, an illumination product also performs a light-supplementing automatically for the camera to realize a constant light control over a shooting.
