The invention provides an image processing method and equipment. The method comprises the following steps of judging whether the length and width of a target object acquired by zooming an image to be processed according to a given factor are integers; if yes, then zooming according to the given factor to get the target image; otherwise, acquiring the target image by means of a linear interpolation method according to a first zoom image and a second zoom image, wherein the first zoom image and the second zoom image are integral images. The integral images are images acquired by zooming images to be processed according to a standard factor and having a length and a width being integers. The standard factor is a zooming factor corresponding to the integral images. A first factor is any standard factor smaller than the given factor but with an interval from the given factor located within a first preset value. A second factor is any standard factor larger than the given factor but with an interval from the given factor located within a second preset value. By means of the provided method and equipment, distortion after image zooming can be alleviated.
