Abstract

An illumination measuring device for panoramic picture taking has a first photoelectric illumination intensity receiver which diffusely determines light falling in a first measuring region and illuminating a first panoramic portion, at least one further photoelectric illumination intensity receiver which diffusely determines light falling in a second measuring region and illuminating a further panoramic portion, and an evaluating unit determining a deviation of an illumination intensity determined by the further illumination intensity receiver from an illumination intensity determined by the first illumination intensity receiver.
