A sensor unit (100) for ascertaining control data for use in a daylight-dependent light-controlling device comprises an image sensor (10) for acquiring digital image data as well as a controller (20) for analyzing the image data and creating a brightness signal representing the daylight. The controller (20) is designed such that when creating the brightness signal, same gives more weight to those image regions of the image data acquired by the image sensor which are more greatly influenced by the daylight. |
