A display control apparatus obtains coordinate information indicating a specific coordinate on a display surface that a user activity is detected, determines whether a first image to be drawn at a position indicated by the coordinate information, at least partly overlaps a second image to be displayed together with the first image, and changes order information stored in a memory so as to cause the first image layer to be superimposed on the second image layer based on a determination indicating that the first image at least partly overlaps the second image.
