Abstract: In order to solve the problem of the photo response non-uniformity (PRNU) for
High Dynamic Range (HDR) video system, this paper discusses the causes of the problem and the
common solution, and then proposed a new non-uniformity correction approach based on the
reference source for HDR video system. This approach use high-pass filter to calibration image in
Frequency domain to get the correction matrix of one level light conditions at first. And then
performs an inverse Fourier transform to the spatial domain. Finally calculate the difference
between the correction matrix and the target image to obtain the corrected results. The
experimental result indicates that the approach has good effect on dealing with non-uniformity
of the HDR images and the definition has been greatly improved. © (2013) Trans Tech
