Abstract: Methods, systems, and devices for image processing are described. The method includes capturing from a sensor a first image frame using an initial exposure length, calculating, based on a clipping status of a set of one or more pixels of the first image frame, a predicted exposure length and a hedged exposure length, where the predicted exposure length is different from the hedged exposure length by at least a threshold, capturing from the sensor a first array of pixels using the predicted exposure length and a second array of pixels using the hedged exposure length, capturing from the sensor a second image frame using a converged exposure length, where the converged exposure length is based on a comparison of a saturation of the first array of pixels to a saturation of the second array of pixels, and outputting the second image frame.
