Claim:
A method of controlling a lighting of a room in accordance with an image projected by a projector onto a dedicated projection screen, which method comprises: controlling, at a control unit that is autonomous from the projector, a plurality of lighting devices in a lighting arrangement in the room; measuring a number of characteristic features of the projected image on or behind the projection screen using a plurality of sensors coupled with the control unit to measure luminous intensity and color; adjusting, by the control unit, the lighting devices of the room based at least in part on the measured characteristic features; projecting in an area surrounding the projection screen with light of a color and luminous intensity matching adjacent areas at the edges of the projected image; wherein a number of zones of a surrounding area of the projection screen are illuminated individually by one of the lighting devices on the basis of the measured features; wherein said measurements of the characteristic features are performed in specific measuring areas at the edges of the projection screen and the zones of the surrounding area adjacent to the specific measuring areas are illuminated on the basis of the measurements at the specific areas; wherein, in a first phase, the room lighting is off, and measurement of the characteristic features of the image is performed, and wherein, in a second phase, the room lighting is on, and measurement of characteristic features of the room lighting is performed, and wherein an adjustment of the room lighting is carried out on the basis of the measurements performed in both first and second phases.
