The present invention provides a display control method and a display control device capable of detecting a position and an orientation of an apparatus by a simple structure and controlling a display of a displayed image based on the detected position and orientation of the apparatus with ease. Two cameras are mounted on the apparatus. A user holds the apparatus in the hand, captures, by a first camera, a first image including the face of the user, and captures, by a second camera, a second image including a scene opposite to the user. A display control unit extracts features of the face from the first image and extracts scene feature points from the second image. Then, the display control unit compares the extracted results with reference graphics and the like, and calculates a user-to-apparatus distance ro and angles thetao, phio which indicate a direction to the apparatus, and controls the display of the displayed image based on the calculated distance ro and angles thetao, phio.
