The invention relates to a method and a system for regulating the brightness of target zone lighting means that illuminate an interior target zone of an interior. The method comprises the following steps: optically mapping at least part of the interior to an interior image by means of spatially resolved brightness sensor means; determining a present brightness value vector, the components α(t) of which correspond to present integrated brightness values of an i-th interior image zone; determining a target zone brightness control value from the scalar product of the present brightness value vector and a target zone calibration vector associated with an interior target zone; and regulating the target zone brightness control value to a target zone brightness setpoint value by adapting the illumination intensity of the target zone lighting means.
