| Abstract: | In order to improve the visual effect of low illumination video,a hybrid algorithm was proposed,which included the Logarithmic Image Processing(LIP)-based enhancement algorithm and the improved bi-direction balancing algorithm.The number of processing frames was reduced by using the inter-frame cross-correlation to improve the processing speed.Experimental results show that the proposed algorithm can obtain more satisfactory results. |

| Keywords: | video enhancement contrast enhancement low illumination cross-correlation |
