1. An image processing method, comprising:
obtaining N images, wherein the N images have a same quantity of pixels and a same pixel location arrangement, each of the N images include images of a target object, N is an integer greater than 1, and the N images are obtained from N consecutive video frames in a raw video;
obtaining, based on feature values of pixels located at a same location in the N images, a reference value of the corresponding location;
determining a target pixel of each location, from pixels at the same location in each of the N images, based on the reference value of the location; and
generating a target image based on the target pixel of each location, the target image comprising at least two images of the target object from the N images, at least one of the images of the target object in the target image being superposed, such that the target image displays the target object in two different locations or positions at two different times.
