Abstract
The present disclosure discloses an image enhancement method and device. The method comprises: performing logarithm related processing on a grayscale value matrix Y of an original image to obtain a logarithmic matrix L_LOG; quantizing the logarithmic matrix L_LOG to obtain a quantized matrix Y_RE; and obtaining an enhanced image of the original image according to the quantized matrix Y_RE, wherein quantizing the logarithmic matrix L_LOG comprises: when the logarithmic matrix L_LOG is quantized to be within a grayscale range of a certain depth, causing a zero point of the logarithmic matrix L_LOG to be close to an average value of the grayscale value matrix Y.
