The image data is inverted, treated by a digital lighting process, the subsequently inverted again. This allows the set of data image to be treated for dynamic range compression of detail in both the dark regions and the light regions by the same algorithm. In other words, the process applied to the dark regions can be performed by a correction algorithm and the process applied to the light regions performed by the same algorithm, but with the image data negated before and after the correction algorithm is applied."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Highlight recovery using digital lighting module","description":"The described methods and corresponding apparatus are for use in highlight recovery in a set of image data.
