    • The present invention relates to a method for illuminating a scene having an average lighting setting, the method comprising the steps of receive scene information from an image sensor (110) comprising a plurality of pixels, determine chromaticity coordinates for the scene based on the scene information, and determine, based on the chromaticity coordinates, control values used for driving the at least two differently colored light sources (L 1 , L 2 , L 3 ), thereby allowing for illumination of the scene without essentially changing the average lighting setting of the scene. The present invention provides for the possibility to in a more precise way match the average lighting setting of the scene, wherein it is possible to produced light that assure a more natural rendering of illuminated objects in the scene. In comparison to the prior art, for light sources which have spectra far from the black body curve, the chromaticity coordinates are a better representation of the color of ambient light illuminating the scene than when using the correlated color temperature. The present invention also relates to a corresponding illumination device (100).
    • 本发明涉及一种用于照明具有平均照明设置的场景的方法,所述方法包括以下步骤:从包括多个像素的图像传感器(110)接收场景信息,确定色度坐标 针对基于场景信息的场景,并且基于色度坐标确定用于驱动至少两个不同颜色的光源(L 1,L 2,...,L)的控制值, >,L <3>),从而允许对场景进行照明而基本上不改变场景的平均照明设置。 本发明提供了以更精确的方式匹配场景的平均照明设置的可能性,其中可以产生确保场景中照明对象更自然地呈现的光。 与现有技术相比,对于具有远离黑体曲线的光谱的光源,与使用相关色温相比,色度坐标是照亮场景的环境光的颜色的更好表示。 本发明还涉及相应的照明装置(100)。
