The embodiment of the invention provides an image processing method and device. The method comprises the following steps that the terminal equipment performs brightness matching processing on each original brightness value of a second image in a brightness color space by utilizing a proportion between an original brightness mean value of a first image in the brightness color space and an originalbrightness mean value of the second image in the brightness color space to obtain a second image after brightness matching processing, and then replaces each color value of the second image in the brightness color space after brightness matching processing with the color value of the first image in the brightness color space to obtain a second image after color matching with the first image. The color matching degree between images with different characteristics can be improved, and meanwhile, the calculation complexity is reduced, so that the fusion is facilitated to obtain a high-quality image. 本申请实施例提供了一种图像处理方法及装置。
