High Dynamic Range Color Imaging with a Camera Based on Piece- wise Color Characterization

摘要

In this paper, we put forward a new method of multiple exposures high dynamic range color imaging with a RGB camera based on a piecewise color characterization model. The construction of the piecewise color characte rization model, and the method of images capturing, the color tone mapping and the images combination based on this piecewise color characterization model were introduced. By using an ordinary color camera NikonD70s, we demonstrate our new method can obtain desired high dynamic range images with standard color information.
