  • Patent number: 10130248
    Abstract: A method by which fundus photographs that are corrected for scattered light can be realised by using a digital fundus camera. The fundus is illuminated and a photograph of the fundus is realized. The photographed area is greater than the illuminated are. The scattered light intensity is determined and is used for correction. Measurement points for determining the scattered light intensity are defined in the non-illuminated area. Values of the scattered light intensity determined at the measurement points are averaged. Average-scattered light intensity thus determined is subtracted from the intensity values of the photograph to correct the photograph.
