Abstract
A method for capturing a high-dynamic-range image includes: (i) storing a plurality of pixel values representing a first image captured by an image sensor that includes a pixel array, each pixel value having been generated by a respective pixel of a pixel subarray of the pixel array, each pixel being set to one of Nfirst exposure values, N≥1; (ii) determining an exposure-count Nbased on the plurality of pixel values; (iii) setting each pixel to one of a second plurality of exposure values, Nin number, such that, for each of the second plurality of exposure values, at least one pixel is set to that exposure value, one of the second plurality of exposure values differing from each of the Nfirst exposure values by more than a threshold value; and after setting (iv), capturing a second image with the image sensor.
