Abstract: This application provides an image processing method and an electronic device. The method includes: obtaining a first image and a second image that are acquired at a same acquisition moment, where the first image is obtained by using a first photographing unit to acquire an image in a first acquisition region, and the second image is obtained by using a second photographing unit to acquire an image in a second acquisition region, where a parameter of the first photographing unit and a parameter of the second photographing unit are the same, and there is an overlapping acquisition region between the first acquisition region and the second acquisition region; and determining, according to the first image and the second image, whether the first photographing unit and the second photographing unit are normal.
