Abstract: The invention relates to a method for acquiring an image by an imager (20) comprising a matrix of pixels configured to generate an electric response when exposed to an incident light flux travelling through an optical path (21) in which is arranged a wavefront correction element (22), comprising the following steps: 1) initiating the exposure of the pixels to the incident light flux; 2) for a plurality of iterations during the exposure: 2.1) non-destructive reading of the electric responses of pixels of a region of interest; 2.2) determining an evolution of the spatial distribution of pixels in logarithmic mode previous iteration with respect to the previous iteration; 2.3) based on said evolution, establishing a command for the wavefront correction element (22) in order to correct the wavefront; 2.4) configuring the wavefront correction element, 3) reading the electric responses of the pixels resulting in an image.

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.
