An image can be captured as a captured image at a capture exposure. The exposure of a current iteration of the image can be changed by at least a fraction of an exposure value. A changed exposure image can be captured at the changed exposure value. A difference between an exposure data metric of the current iteration of the changed exposure image and an exposure data metric of a previous iteration of the image can be ascertained. The difference between the exposure data metric of the current iteration of the changed exposure image and the exposure data metric of the previous iteration of the image can be compared to a difference threshold. Changing the exposure value, capturing the changed exposure image, ascertaining the difference, and comparing the difference can be repeated when the difference between the exposure data metric of the current iteration of the changed exposure image and the exposure data metric of the previous iteration of the image exceeds the difference threshold."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for auto exposure value detection for high dynamic range imaging","description":"A method and apparatus for auto exposure value detection for High Dynamic Range (HDR) Imaging.
