Abstract:
1. An image processing device comprising: an imaging section equipped with an image sensor; and a processor which is operable as: a detecting section which detects an augmented reality marker from within an actual image captured in the image sensor; a recognizing section which recognizes the augmented reality marker detected by the detecting section; an imaging direction identifying section which identifies an imaging direction when the recognizing section recognizes the augmented reality marker, wherein the imaging direction identifying section identifies the imaging direction by calculating the imaging direction from a location, size, and position of the augmented reality marker from within the actual image, the imaging direction being a direction from the position of the augmented reality marker within the actual image toward the image sensor; a rotation angle calculating section which calculates an angle between the imaging direction and a reference direction of the augmented reality marker, wherein the calculated angle serves as a rotation angle; and a display control section which controls and performs a superimposed display of a virtual object on a display according to at least a first display mode and second display mode, wherein in the first display mode, the display control section controls and performs a superimposed display of the virtual object so that the virtual object is directed toward a predetermined direction based on the reference direction of the augmented reality marker, without reference to the calculated imaging direction and rotation angle, and in the second display mode, the display control section controls and performs a superimposed display of the virtual object so as to rotate the virtual object by the calculated rotation angle from the reference direction of the augmented reality marker so that a predetermined direction of the virtual object is directed toward the imaging direction.
