A method includes: capturing at least two frames of first images at a same exposure time using a first camera, and capturing at least two frames of second images at different exposure times using a second camera, where a capturing time of the first images and a capturing time of the second images are the same; determining a first reference image from the at least two frames of first images; performing moving target detection on an image other than the first reference image in the at least two frames of first images according to the first reference image to obtain a local motion magnitude that is of the image other than the first reference image in the at least two frames of first images and that is relative to the first reference image; and performing image fusion on the second images according to the local motion magnitude.
