Image processing technologies and acquisition methods and apparatus are provided. A method comprises obtaining at least two images of different image quality of a target scene, and combining, according to data characteristics of the at least two images, the at least two images locally to obtain a target image. In a method and apparatus of the embodiments of the present application, local combination is performed on at least two images of different image quality according to data characteristics of the images, so that the dynamic range and/or signal-to-noise ratio can be improved locally on the basis of presenting image details as fully as possible, that is, the image quality can be improved according to requirements.
