Abstract
Systems and methods are disclosed that address the need for adaptive exposure within high dynamic range (HDR) images. Solutions can leverage recent advances in the use of virtual reality (VR) headsets and Augmented Reality (AR) displays equipped with infrared (IR) eye tracking devices. A gaze vector determined by the eye tracking device identifies one or more fixation points on the image that corresponds to an area where there exists a faulty exposure. The exposure around the fixation point can be adaptively corrected using image processing techniques. Using spatial adaptive exposure, the resulting image, a type of foveated image, can be rendered on a low dynamic range (LDR) display with sufficient detail.
