Abstract
A method determines a pixel value in a high dynamic range image from two images of different brightness by obtaining corresponding input pixel intensities from the two images, determining combination weights, and calculating the pixel value in the high dynamic range image as a weighted average of the input pixel intensities. Another method determines a pixel value in a high dynamic range image from more than two images by forming pairs of corresponding input pixel intensities, determining relative combination weights for the input pixels intensities for each pair, applying a normalization condition to determine absolute combination weights, and calculating the pixel value in the high dynamic range image as a weighted average of the input pixel intensities. Systems for generating high dynamic range image generation from two or more input images include a processor, a memory, a combination weight module, and a pixel value calculation module.
