| Zusammenfassung: | The invention provides an image processing method and device. The method comprises the steps that an original brightness image of an original image is decomposed into N orders by wavelet transform; for each decomposed image, the corresponding frequency of each pixel in the decomposed image is adjusted according to a frequency adjustment threshold corresponding to the decomposed image, wherein the frequency higher than the frequency adjustment threshold is adjusted lower, and the frequency lower than the frequency adjustment threshold is adjusted higher; according to each decomposed image obtained after frequency adjustment, an adjusted brightness image corresponding to the original image is reconstructed; according to the original image, the original brightness image and the adjusted brightness image, a processed image corresponding to the original image is determined. The image processing method and device can reproduce image details and enhance details in areas with less prominent details, and can enhance t |
