1. A method for regulating the brightness of target zone lighting means (14a, 14b) illuminating an interior target zone (16a, 16b) in an interior space (10), comprising the following steps:
optically mapping (S1) at least part of the interior space (10) onto an image (20) of the interior space by spatially resolved brightness sensor means (18), wherein the image (20) of the interior space includes at least two interior image zones (22a, 22b, 22c, 22d),
determining (S2) a current N-dimensional brightness value vector the ith component of which each corresponds to current integrated brightness values of the ith interior image zone (22a, 22b, 22c, 22d), wherein t is the current time, wherein the dimension N is greater than or equal to 2 and the index i runs over at least one subset of the set of interior image zones (22a, 22b, 22c, 22d),
determining (S3) a target zone brightness regulation value from the scalar product of the current brightness value vector and an N-dimensional target zone calibration vector associated with an interior target zone (16a, 16b),
regulating (S4) the target zone brightness regulation value to a target zone brightness set value by adjusting the respective illumination intensity of the target zone lighting means (14a, 14b).
