methods and apparatuses for generating a low dynamic range image for a high dynamic range scene . in one aspect , a method to generate a low dynamic range image from a high dynamic range image , includes : determining one or more regions of the high dynamic range image containing pixels having values that are outside a first range and inside a second range ; computing a weight distribution from the one or more regions ; and generating the low dynamic range image from the high dynamic range image using the weight distribution . in another aspect , a method of image processing , includes : detecting one or more regions in a first image of a high dynamic range scene according to a threshold to generate a mask ; and blending the first image and a second image of the scene to generate a third image using the mask .
