Method and lighting system for individually controlling illumination of a plurality of sub-areas commonly constituting an overall illumination area of a controllable light source. An environment sensor senses an environment at least corresponding to the overall illumination area and generates a representation thereof. A processing unit analyses the representation for determining objects and/or regions in the representation. The processing unit further sets a setting value for the at least one lighting parameter for each of the plurality of sub-areas depending on the determined object and/or regions, and a controlling unit controls light emission of the controllable light source according to the determined values for each of the plurality of sub-areas.
