Abstract: A method includes obtaining a first image of a to-be-photographed object based on an input received by way of a user interface, the first image being obtained using a terminal having a lens in a first position. The method also includes detecting a moiré pattern on the first image. The method further includes automatically moving the lens from the first position to a second position on a plane perpendicular to an optical axis of the lens. The method additionally includes obtaining at least one second image of the to-be-photographed object one or more of with the lens in the second position or between the first position and the second position. The method also includes restoring a detected moiré pattern region of the first image based on the at least one second image to generate a restored image. The method further includes outputting the restored image to a display.
