Compact approach for high dynamic range imaging in mobile digital camera

摘要

This paper describes about compact approach for high dynamic range imaging in the mobile camera. The dynamic range of real world is much larger than that of the mobile sensor. So it's almost impossible to make high dynamic image with just one shot. This paper focuses on the small number of frames for high dynamic range imaging synthesis and the complexity of algorithm. With only one short and long exposure frames we calculate radiance map in the Bayer domain, process tone mapping with multi-layer decomposition method and compensate for motion artifacts for moving objects.
