SYSTEM AND METHOD FOR PROCESSING INPUT IMAGES BEFORE GENERATING A HIGH DYNAMIC RANGE IMAGE

摘要

An image processing system serves the purpose of generating a high dynamic range image from a first image and a second image. The system comprises a first displacement estimator (22) adapted to estimate a displacement of image content between a reference image derived from the first image and an image to be warped derived from the second image. Moreover it comprises a first warping unit (23) adapted to compensate the estimated displacement by warping the image to be warped resulting in a first warped image. Moreover, the system comprises a first error detector (24) adapted to detect geometric warping errors within the first warped image and a first error compensator (25) adapted to compensate the estimated geometric warping errors within the first warped image resulting in a first error corrected image. Also the system comprises a high dynamic range calculator adapted to calculate the high-dynamic range image based upon the first error corrected image and the reference image.
