  • Image processing method for producing a high dynamic range image of a scene
    Patent number: 11882367
    Abstract: An image processing method comprises: performing a spectral analysis of a HDR image (220) to determine whether the HDR image (220) comprises spectral components indicative of a lighting of the scene by a modulated light source; analysing meta-data associated with a set of component images (221) for the HDR image to determine a difference between meta-data for one component image of the set and meta-data for at least one other component image of the set, any difference being indicative of an artefact caused by illumination of the scene by a modulated light source; combining a result of the spectral analysis and the meta-data analysis to provide an indication that illumination of the scene by a modulated light source is causing a visible artefact in at least one of the HDR images; and changing a HDR operating mode of the image processing system (200) accordingly.
