Abstract
A method for converting a standard dynamic range (SDR) sequence into a high dynamic range (HDR) sequence is described. The method includes determining (S) successive shots in the SDR sequence by cut detection, detecting (S) if the SDR sequence comprises a sub-sequence of at least two successive short shots having a duration lower than D, said subsequence comprising at least one bright shot having a luminance and a size greater than Land SZrespectively, and mapping (S) the luminance range of bright shots of the detected subsequence from the low dynamic range to a first high dynamic range and mapping the other shots of the SDR sequence from the standard dynamic range to a second high dynamic range in order to generate the HDR sequence, the first high dynamic range having a maximal value Llower than that of the second high dynamic range L.
