The paper proposes a novel method to correct the temporal inconsistency in exposure of video sequences captured from CMOS cameras. The temporal exposure consistency is improved by avoiding significant change in histogram over frames. This is done by histogram equalization where the target histogram is the temporal low-pass filtered result from the previous frames' histogram. Simulations on different video sequences verify the effectiveness of the algorithm.
