Abstract: The embodiment of the present application provides an image processing method and device, and relates to the technical field of image processing. The method includes: obtaining a to-be-processed image; obtaining a first image that is obtained by performing resolution reduction processing on the to-be-processed image; performing image processing on the first image to obtain a second image; and increasing a resolution of the second image to a preset resolution as an image processing result. Applying the solution provided in the embodiments of the present application for image processing can reduce the requirements on image resolution in an image processing process.
