An image processing method includes a position/orientation acquisition step of acquiring a position and orientation of a viewpoint, a virtual image creation step of creating a virtual image on the basis of the position and orientation of the viewpoint, and a holding step of holding an environment mapping image. In addition, an image extraction step extracts a mapping image area rotated according to a viewpoint rotation component about an axis in a line-of-sight direction from the environment mapping image on the basis of the line-of-sight direction of the viewpoint and the viewpoint rotation component about the axis in the line-of sight direction, and an environment mapping step executes environment mapping processing for the virtual image created in the virtual image creation step by using an image included in the mapping image area extracted in the image extraction step.
