Abstract
Systems, methods, and non-transitory media are provided for automatic exposure control. An example method can include receiving pixel values captured by a photosensor pixel array (PPA) of an image sensor, wherein one or more pixel values from the pixel values correspond to one or more sensitivity-biased photosensor (SBP) pixels in the PPA and one or more saturated pixel values from the pixel values correspond to one or more other photosensor pixels in the PPA; determining, based on the one or more pixel values, an actual pixel value for the one or more pixel values and/or the one or more saturated pixel values; determining an adjustment factor for at least one of the pixel values based on the actual pixel value and a target exposure value; and based on the adjustment factor, correcting an exposure setting associated with the image sensor and/or at least one of the pixel values.
