The paper proposes image enhancement by multi-scale Retinex for signal depth of field which has the character of low contrast,little of available message and low of differentiability.According to the character of signal depth of field,multi-scale Retinex adopts multi-scale Gaussian filter filtering with original picture in space based on average standard deviation.At last,the paper deals with pictures by gray level equalization,the outcomes show that this method plays well.
