    • 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 (L1, L2, L3), 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亮具有平均照明设置的场景的方法,该方法包括以下步骤:从包括多个像素的图像传感器(110)接收场景信息,基于场景信息确定场景的色度坐标 ,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(L1,L2,L3)的控制值,从而允许场景的照明,而不会基本上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亮物体更自然的渲染的光。 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的表示。 本发明还涉及相应的照明装置(100)。

    • Method, device and system for generating a light control parameter for controlling light (20), e.g. ambient light, in response to an audio signal (A). The audio signal (A) is analyzed in order to extract a temporal evolution of semantic content of the audio signal (A). A light control parameter is then generated according to the temporal evolution of semantic content of the audio signal (A), either on-line or off-line. This enables generating light that is perceptually aligned with the audio signal, e.g. music. In a preferred embodiment spatial properties of the audio signal (A) are extracted, and separate light control parameters are generated for controlling light sources spatially positioned according to the spatial properties of the audio signal, e.g. for stereo or surround sound systems where light sources are positioned near each loudspeaker. Such embodiment enables spatial correspondence between light and audio. In another preferred embodiment semantically distinct temporal sections of a sequence of the audio signal (A) are determined, e.g. sections of a piece of music, and wherein the light control parameter is generated to reflect these sections of the audio signal (A). Such embodiment enables temporal changes in light that follow perceived changes in e.g. a piece of music. Applications of the described method is e.g. within home entertainment systems, theatres, jukeboxes, bars, restaurants, cinemas and discotheques.

    • The invention relates to a method of controlling a temporal variation of light emitted by an illumination system. The light emitted by the illumination system varies from light having a start color point (14) to light having a target color point (12). The start and target color point are defined in a first color space (XYZ, RGBvid, RGBill), which is perceptually non-uniform. The method according to the invention converts the start and target color point from the first color space to a second color space (Lab, Lch), which is more uniform to the human visual system than the first color space. The method further comprises a step of generating an intermediate color point (34, I1, , I2) located on a transition-path (p, p′) within the second color space, an intermediate distance (d) between the start color point in the second color space and the intermediate color point in the second color space not being larger than a threshold distance (26). The method further comprises converting the intermediate color point from the second color space back to the first color space, and subsequently altering the light emitted by the illumination system (65) from the start color point to the intermediate color point. The invention further relates to an illumination system and a display device.
