  • Adaptive generation of a high dynamic range image of a scene, on the basis of a plurality of images obtained by non-destructive reading of an image sensor
    Patent number: 10924687
    Abstract: High dynamic range (HDR) images are generated on the basis of a plurality of images obtained by non-destructive reading of an image sensor, called NDRO images. An HDR image generation method includes: the determination of a criterion of desired quality for the HDR image; at least two non-destructive readings of the sensor delivering at least two successive NDRO images; the selection, as a function of the criterion of desired quality, of the first and of the last NDRO image to be used to generate the HDR image; the generation of the HDR image on the basis of information extracted from a series of successive NDRO images starting with the first and terminating with the last NDRO image to be used; the storage of a single image at one and the same time throughout the entire HDR generation phase.
